FAQs

In a network there is a server which stores, processes and distributes information; on the other hand there is a "client" which refers to a device which connects to the server to access information.

To use the warning mail function, it is necessary to have access to a SMTP/POP server.If you have an Internet connection, use the mail server of your Internet service provider or some other means to access a mail server. If you have a mail server on your company LAN, there may be specific instructions and settings for sending mail. Please ask the network administrator at your company for details.

When using a TR-7wf/nw device with T&D WebStorage Service, it is not necessary to make SMTP server settings to send warning report mail from the WebStorage Server.

POP3before is one method used for the sending and receiving of mail.
A mail server uses two types of protocol to send and receive mail. Generally when mail is sent it uses an SMTP server and when receiving mail uses a POP server.
Normally, the sending and receiving of mail are done separately. However, recently in an effort to fight Spam mail a new type of mail server, referred to as POP3before, has been developed.

The way it works is that after logging in with your Login ID and password to the POP server you can then have access to the SMTP server for a certain length of time in order to send mail.

POP3before is controlled by the administrator of your company LAN or by your provider and unfortunately there is nothing that you can do to cancel it.

If you wish to use the warning mail function, please make sure to use a mail server that complies with normal SMTP / POP specifications.

Indoor partition walls, ceilings, metal, and other obstacles can shorten the radio transmission range compared to an environment where radio waves can travel in a straight line from the Remote Unit to the Base Unit without any obstacles.

Radio waves also pass through and around obstacles leaking from gaps or spaces. Hence the transmission range depends on the building construction and contents of the rooms. Therefore, it is difficult to say what the transmission range will be when using in an indoor environment.

The wireless radio frequency output during communication in the RTR-500 and RTR-7 Series are about 10mW; about the same as a low power transceiver.

Output for the RTR-5 Series is just one-tenth of that or 1mW.Hence no effect will occur on nearby devices or equipment.
Moreover, the devices are registered with the proper authority and comply with local regulations (FCC or CE); there should be no interference with communication of other nearby devices.

Yes, high output wireless devices or other electronic devices which put out high levels of noise in close proximity will have an effect on communication.

RTR-500, RTR-7 and RTR-5 Series are all designed with a retry function that will resend a communication that was not successfully completed.

Moreover, in the RTR-7 Series, if noise or other trouble is detected before communication is carried out, the base unit will automatically search out a unaffected frequency channel to carry out communication.
Note however that even with these features successful communication can not be guaranteed.

If two or more wireless loggers from the same series are used in separate logging systems it may cause interference.

The RTR-500, RTR-7 and RTR-5 Series are all designed with a multiple number of frequency channels for communication between the Base and Remote Units. If interference occurs or you think it may occur, it is possible to change the frequency channels to alleviate that problem.

For the RTR-500 Series and the RTR-5 Series it is possible to make frequency channel settings when registering loggers as Remote Units to a Base Unit.
In the RTR-7 Series, the Base Unit has a function to auto-search for unused channels whereby settings can be made.

In almost all of our data loggers there is no feature allowing you to clear data in and by itself.By stopping and restarting recording, all data will automatically be cleared.

In the MCR-4V and MCR-4TC it is possible to delete all recorded data from both the unit itself and via PC software.

Use in such an environment should be avoided; the exposure to gas will cause corrosion.

No, it cannot be used in a vacuum.

T&D data loggers basically come in two model types. Some models can record up to 8000 readings before becoming full and other models can record up to 16.000 readings before becoming full.

The amount of time that a logger can continuously record will be determined by the number of readings it can record and also by the recording interval at which it is set to record.
Below is a chart showing the longest amount of time each of the types of loggers can record before becoming full.
Please use this data as an estimate when deciding which type of logger to purchase.

IP64 is a rating for everyday use; meaning it is splash resistant.Therefore splashes of water from a sink or rain will not be a problem, but it cannot be guaranteed for use while submersed in water.

The unit itself can be submersed in cold or hot water for a short time without water entering the unit. But if for example it was in hot water of 60℃ and then moved to cold water of 0℃, the internal pressure of the logger would drop and water may seep into the case.
If you wish to measure and record the temperature in water, please place only the sensor in the water.

Yes, the battery life changes with various factors such as the measuring environment, frequency of communication, recording interval, and quality of the battery being used.

Your batteries may run out faster than stated in the spec or manual depending on the actual operating environment and conditions of use.
Please regard the estimated battery life as a reference.

For wireless data loggers, battery life is calculated based on the assumption that recorded data is downloaded via wireless communication once a day.

Monitoring current readings, for example, that requires frequent wireless data transmission, will shorten the battery life.

For non-wireless data loggers, the basic assumption used is a 10-sec (or longer) recording interval and transmission frequency of 4 times a month.

Yes, recording in the data logger is not affected by communication with the PC.
Measurement and recording will continue during communication.

If the installation has failed first please check to make sure that the version of the software you used is compatible with Windows 7.
If it was compatible but still the PC did not recognize the driver, please see the link below and try reinstalling the USB driver.

Reinstalling USB Driver on Windows 7

Because the temperature durability range for the humidity sensor is lower and both the temperature and humidity sensors are inside one case, the possible measurement range becomes narrower.

An adjustment function for temperature measurements is available in the following models. (As of March 2016)

- TR-51S/52S
- TR-51i/52i/55i
- RTR-51A/52A/53A/52Pt
- RTR-501/502/503/505/507/574/576
- TR-71U/72U
- TR-71Ui/72Ui
- TR-71wf/72wf
- TR-71nw/72nw
- TR-73U
- TR-74Ui
- TR-76Ui
- TR-77Ui
- TR-71W/72W
- TR-701AW/702AW
- TR-701NW/702NW
- RTR-61

There is no adjustment function available for any models other than stated above.

Even if a measurement goes above or below the range noted in the specifications it will appear on the display and will be recorded, but the measurement is not guaranteed to be accurate above or below the stated range.

Yes, thermocouple sensors can be used with the following loggers: MCR-4TC, RTR-505-TC and TR-55i-TC. We do not handle or sell thermocouple sensors, so please purchase elsewhere.

In general it stands for a condition in which there is a lag in response exhibited when reacting to changes in external forces so that although the conditions have been met for the affected body to return to its original state it does not for some time.

Capacitance type humidity sensors (HHA-3151, HHB-3101) used in our High Precision Wide Range Temperature and Humidity Data Loggers will exhibit hysteresis upon returning to normal from very high humidity. Differences of ±1.5%RH may occur.

Moreover, when used in high temperature and high humidity environments (50℃/75%, 60℃/50%, 70℃/35%, and 80℃/25%) sensor hysteresis may become even larger and exceed ±1.5%RH. Note that under certain circumstances, it may take several days to return to normal.

The circuitry in the device has been designed to withstand the effects of changes in the surrounding environment and changes in electrical properties; therefore the precision of the measurements does not degrade over time.

Although the sensor element of the temperature sensor does not experience loss of precision due to use over time, due to external factors, such as build up of water, losses in precision will occur.

If you find that measurements are becoming less and less precise, we suggest changing the sensor.
Humidity sensors will also lose precision due to water and dust buildup.

This is an estimate of response time based on JIS standards.
It is the amount of time it takes for the 63.2% of the temperature measurement to be reached.

The maximum length and compatible extension cables vary depending upon which logger is being used.

Up to 3 meters of extension cables can be used per sensor/module.

【RTR-503, RTR-72, RTR-53/53A】

Extension cables cannot be used with these models.

The fluororesin part of the fluoropolymer coated sensor and the stainless protection tube of the stainless protection sensor are submersible and can be used in water applications. Other sensors cannot be submerged in water.

Basically, our waterproof sensor lineup can be broken down into three categories.
Please make a choice depending upon your individual needs.

1: Sensor tip (stainless protection tube) is waterproof but cable is not.
The following fall into this category: TR-0306, TR-0406, TR-0506, TR-0706.
These are optional sensors for TR-71wf/71nw, TR-73U, TR-71Ui/72Ui, TR-71U/72U, TR-701NW/701AW and TR-71W/72W.

2: Sensor tip (stainless protection tube) is waterproof and cable is rated for short term immersion (IPX7).
The following three kinds fall into this category:
a) TR-1220 and TR-1320
These are optional sensors for TR-71wf/71nw, TR-71Ui, TR-701NW/701AW, TR-71W and TR-71U.

b) TR-5220, TR-5320, and TR-5420
These are optional sensors for RTR-502, TR-52i, TR-52(S), RTR-52/52A and RTR-71.

c) TR-81XX
This is an optional sensor for RTR-505-Pt, TR-55i-Pt, TR-81 and RTR-52Pt. The Pt sensors can be ordered with tip (stainless protection tube) lengths from 50mm to 2000mm. (L-types included)

*Immersion proof (IPX7) means the object can be put into water of up to 1m in depth for 30 minutes without intrusion. Therefore the part which is rated for short term immersion can not be used continuously immersed in water.

3: From tip to cable connector is rated for continuous immersion (IPX8).
The following fall into this category: TR-5106 and TR-5530
These are optional sensors for RTR-502, TR-52i, TR-52(S), RTR-52 and RTR-71. (including L type)

It is possible only for platinum resistance sensors used with logger models TR45, RTR-502Pt, TR-55i-Pt, TR-81 and RTR-52Pt and thermocouple sensors used with TR45, MCR-4TC, RTR-505-TC and TR-55i-TC loggers. For all other products it is necessary to use T&D designed thermistor sensors.
Other manufacturer's thermistor sensors are not compatible with T&D products.

The sensor area is 3-5mm from the tip.
This is common for all external temperature sensors.

Attached to our older model temp-humidity sensors (TR-3100/TR-3110/TR-3220) are two stickers: a wetness detection sticker and a temperature detection sticker.
Note that only one sticker (a temperature detection sticker) is attached to our newer model temp-humidity sensors (TR-3310/THA-3001/THA-3151/HHA-3151/HHB-3101).
If any of the stickers shows abnormality, you should replace the sensor immediately.

If it is pink it is normal.
If the sensor was used under high temperature conditions the sticker color will change as shown in the picture to the right.

For the following devices it is possible to use T&D's cloud service and/or software to automatically upload/collect current readings at a set interval and then view in graph form. Shortest possible intervals and methods for auto data upload/collection vary depending on the device, therefore please check the user's manual or HELP in the software for details.
