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
