Battery Installation and Replacement

When the battery is inserted, recording will start automatically with the default or previous settings.
Default Settings
Recording Mode Endless
Recording Interval 10 minutes
Recording Start Method Immediate Start
Sensor Mode (RTR505B) Undefined

You can check if the battery needs replacement by looking at the LCD screen of the Remote Unit, have a warning email sent, or by viewing the T&D WebStorage Service Data View page, Windows Software or Mobile App screen.

When you install or replace the battery, follow the precautions below to keep the waterproof performance of the Remote Unit.

  • Do not remove the battery tube casing from the supplied battery. When using a CR2 lithium battery, the tube is not necessary.
  • If dirt or scratches are present on the rubber packing, water resistance will be reduced. To maintain waterproof capacity, when changing the battery also change the rubber packing and the drying agent (Optional Maintenance Set: TR-00P1).
  • Be sure to completely close the cover. Make sure not to over tighten the screws.
    Appropriate Tightening Torque: 20 to 30N・㎝ (2 to 3Kgf・㎝)
  • Make sure to use the proper type and size screwdriver. (Phillips head #1 screwdriver is recommended.)
  • If a new battery has been installed and recording does not immediately start, nothing appears in the display or any other such malfunction, please remove the battery, check to make sure plus and minus are correct and re-insert the battery.
  • When using for the first time, it may take a few seconds after inserting the battery to start recording; this is not a malfunction.
  • If + (plus) and − (minus) are mistaken, or if the battery terminals + and − are shorted, the recorded data that is stored in the unit will be lost.

About Lithium Batteries

  • When using an LS14250 type lithium battery, even though a new battery has been inserted the [] indicator may remain on for a short time. This is due to a special characteristic of the battery. Note that the longer the battery has been in storage the longer the amount of time, from 10 minutes to about 1 hour, the battery warning mark will remain on. If during that time the Base Unit is used to get the current status of the Remote Unit, the remaining battery level will show that the battery level is low.
  • Please store the LS14250 in a place that is 20°C or less.
  • The estimated battery life of the Lithium Battery LS14250 is about ten months if recorded data is downloaded once a day or the monitoring occurs once every 10 minutes.
  • When using lithium batteries other than LS14250 produced by SAFT, such as CR2, product specifications cannot be guaranteed nor can the performance of some functions, such as the battery warning function.
  • Please avoid using the CR2 in the following situations:
    Using the unit in an environment below 0°C or above 60°C
    Exposing the CR2 to continuous vibration such as in transportation
  • When using a CR2 lithium battery, the tube is not necessary.
  • To maintain waterproof capacity, when changing batteries also change the rubber packing and the drying agent (silica gel). When using a CR2 lithium battery, please purchase the optional Maintenance Set (TR-00P1) to replace the rubber packing and silica gel.

Operating Environment

  • Even if the device has enough battery power to operate under normal temperature, communication may not be possible in low temperature conditions.
  • Avoid long-term use in environments of 60°C or higher, as the unit itself and the parts inside will deteriorate more rapidly.
  • Use in high and low temperature environments will result in a shortening of the battery life as shown below.
    −20°C: one half of life compared to normal temperatures
    −30°C: one third of life compared to normal temperatures
    60°C: one half of life compared to normal temperatures

Precautions Regarding the Sensors and Input Modules

Make sure that the sensor or module is completely inserted until you hear a "click" sound.

Temperature Sensor TR-5106 (for RTR502B)

  • Do not bend or press the last 5cm to the tip of the sensor, as this may damage it.
  • Do not cut or process the cable.
  • If the FEP coating on the sensor and/or the cable has a defect or tear, the waterproof capacity will be lost. Inspect it before operation.
  • Insert the sensor tip to at least 5㎝ or more to obtain an accurate temperature measurement.
  • Use the sensor within its resistance range.

Temp-Humidity Sensor TR-3310 (for RTR503B) / High Precision Temp-Humidity Sensor SHB-3101 (for RTR507B)

  • This sensor is not water resistant.
  • Do not expose to condensation, dampness, corrosive gases or organic solvents. If the sensor gets wet, immediately remove the sensor from the unit and wipe it with a clean cloth as soon as possible. Then allow the sensor to dry in normal room temperature before using it again.
  • Do not expose the sensor to a strong impact. This may adversely affect measurement accuracy and cause damage or malfunction.
  • Continued use may cause a decrease in the sensor's accuracy and sensitivity even under normal operational conditions. Periodic calibration may be required.
  • When the sensor is not to be used for a long period of time, please store it at normal temperature and humidity.
  • When the SHB-3101 is continually used in environments with temperatures above 60°C, accuracy of humidity measurements will decrease over time. Also, humidity cannot be measured at temperatures below −20°C.
  • The TR-3310 has a temperature detection sticker attached to the sensor. If the color changes from light pink (normal) to red, replace with a new sensor.
TR-3310 Temperature Detection Sticker

Thermocouple Module TCM-3010 (for RTR505B)

Insert the miniature thermocouple connector, aligning as shown on the input module. When inserting a sensor into an input module, make sure to match the plus and minus signs on the sensor connector to those on the module.

  • The data logger detects disconnection about every 40 seconds, causing it to display an incorrect temperature directly after a connector is removed.
  • Make sure that the thermocouple type (K, J, T, or S) of the sensor to be connected to the input module, and the sensor type to be displayed on the LCD screen of the data logger are the same. If they are different, change the sensor type using the software or app.
  • Measurement range is in no way a guarantee of the sensor heat-durability range. Please check the heat-durability range of the sensor being used.
  • "Err" will appear in the display of the data logger when a sensor has not been connected, has been disconnected or a wire has been broken.
  • When you wish to use a different type of input module or cable, it is first necessary to initialize the Remote Unit and redo the Remote Unit registration and sensor settings before connecting the new one.

PT Module PTM-3010 (for RTR505B)

  1. Loosen the screws of the terminal block.
  2. Slide the sensor cable terminals through the input module protective cover.
  3. Insert terminals A and B according to the diagram shown on the terminal block and re-tighten the screws.
    In the case of a 4-wire sensor, one of the A wires will be left disconnected.

    Protective Cover
  • Make sure that the sensor type (100Ω/1000Ω) to be connected to the input module, and the sensor type to be displayed on the LCD screen of the data logger are the same. If they are different, change the sensor type using the software or app.
  • Make sure to correctly connect the lead wires according to the diagram shown on the terminal block, and securely tighten the screws to the terminal block.
  • The two "B" terminals have no polarity.
  • Measurement range is in no way a guarantee of the sensor heat-durability range. Please check the heat-durability range of the sensor being used.
  • "Err" will appear in the display of the data logger when a sensor has not been connected, has been disconnected or a wire has been broken.
  • When you wish to use a different type of input module or cable, it is first necessary to initialize the Remote Unit and redo the Remote Unit registration and sensor settings before connecting the new one.

4-20mA Module AIM-3010 (for RTR505B)

Use a tool such as a screwdriver to press down on the terminal button and insert the wire through the hole.
When removing, do not forcibly pull on the wire, but push down on the button as done when installing and gently pull the wire out of the hole.

It is possible to connect a different high impedance device such as a voltage meter to the empty terminals of the module.

  • Do not apply electric current exceeding the input current range. Doing so may damage the input module, causing heat or fire to occur.
  • When you wish to use a different type of input module or cable, it is first necessary to initialize the Remote Unit and redo the Remote Unit registration and sensor settings before connecting the new one.

Voltage Module VIM-3010 (for RTR505B)

Use a tool such as a screwdriver to press down on the terminal button and insert the wire through the hole.
When removing, do not forcibly pull on the wire, but push down on the button as done when installing and gently pull the wire out of the hole.

  • It is not possible to measure negative voltage with this module.
  • When you remove the lead wires from the VIM-3010, core wires will be exposed; be careful of electrical shocks and/or short circuits.
  • When the signal source output impedance is high, a gain error will occur due to the change in input impedance.
    Voltage to be input to "Preheat" should be 20V or lower. Inputting a higher voltage may cause damage to the input module.
  • When the preheat function is not being used, do not connect anything to the "Preheat IN" or "Preheat OUT".
    When using the preheat function, it is necessary that the output signal GND (−) and the power GND (−) are connected together.
  • The LCD refresh interval for the data logger is basically from 1 to 10 seconds, but when using the preheat function the LCD display will be refreshed based on the recording interval set in the data logger.
  • When you wish to use a different type of input module or cable, it is first necessary to initialize the Remote Unit and redo the Remote Unit registration and sensor settings before connecting the new one.

Pulse Input Cable PIC-3150 (for RTR505B)

When connecting the cable to the measurement object, in order to wire properly make sure to match the terminal polarities (RD+, BK−).

  • When you wish to use a different type of input cable or module, it is first necessary to initialize the Remote Unit and redo the Remote Unit registration and sensor settings before connecting the new one.

[OL] will appear if a measurement exceeds the measurement range.

Display Range Exceeded

When measuring voltage in mV range, the measurement in the LCD display will flash if it exceeds the display range of the device.

Measurement Adjustment Function

Adjustment Tools

Using the software Adjustment Tools, it is possible to make adjustments to Remote Unit measurements.

Adjustment for differences will be carried out using an adjustment equation of Y=aX+b; where X is the pre-adjusted reading (Current Reading) and Y is the post-adjusted reading.

1 Point Adjustment
Use this to adjust all measurements with the same offset.
2 Point Adjustment
Use this to adjust measurements in a wide range or when adjustment cannot be carried out using only one point.

T&D Website > Software/Apps > Adjustment Tools Download

 IMPORTANT
  • We cannot guarantee that after carrying out adjustment of the measurement, accuracy will improve for all measuring ranges.
  • When making adjustments to Voltage or 4-20mA, it is recommended to use a point closest to "zero" for adjustment.
  • Adjustment function is set in the sensor/input module, and the settings will remain even if the Remote Unit is initialized. To initialize the adjustment settings, use the Adjustment Tools.
  • When a sensor is replaced, it is necessary to re-make any desired adjustment settings before using the new sensor.
  • If you want to make adjustments to a sensor that has already been adjusted, initialize the setting first.

Device Initialization
