Announcing the New Multi Channel Voltage Recorder: MCR-4V

Date Issued: October 15, 2013

T&D Multichannel Recorder MCR-4V is a 4-channel battery operated voltage data logger. Up to 4 units can be coupled together, making it possible to simultaneously measure and record up to 16 channels.
Quick and precise measurements are made possible with a shortest recording interval of 2 msec, and a minimum voltage resolution of 10 µV.
Besides using a USB connection to directly send recorded data to a PC, it is possible to use an SD card to transfer data from a logger to a PC. Data can also be viewed and checked on the handy LCD display.

Features

Capable of 4-channel measurements and recording with a single unit
Simultaneous measurement and recording for up to 4 units (16 channels) by coupling units.
Runs on 2 AA Alkaline Batteries
Minimum Resolution of 10µV and Input Range of ±±24V
Recording Interval as short as 2 msec
Use of SD Memory Card for Data Transfer to PC
Logging Capacity of 480,000 data readings
Scale and Unit Conversion for each channel
Electrical Isolation between channels
Use of Trend Graph for Checking Data in Real Time

Application Examples

Measure and record data for control devices and measurement instruments in factories
Record signals from actinometers, anemoscopes, rain sensors and CO2 meters
Record output signals from a variety of sensors and analyzers
Measure voltage in electrical circuits

1 : When "Auto" is selected, measurement range will be automatically changed according to the voltage being measured. 2 : If the logging capacity is not filled at the end of one recording session, the logger can record up to 30 times. 3 : A memory card can be used to transfer recroded data from a logger to a PC. However, measurement data cannot be directly recorded into a memory card. 4 : Battery life varies depending upon the frequency of communication, wireless LAN environment, ambient temperature, recording interval, and battery performance. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life.
