TandD 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.

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


Coupling allows for up to 16 Channels to be Recorded Simultaneously

By coupling four units together, it is possible to simultaneously record up to 16 channels.

When the bodies of multiple units are connected, the MCR-4V at the far left side will be automatically designated as the Master and all other connected MCR-4V units will be designated as Slaves.

Group operations such as the starting and stopping recording for the connected units can only be performed via the Master. Upon the start of a group recording, the main recording settings (Recording Mode, Recording Method, 50-60Hz Filter, Recording Interval, and Recording Channel Settings) will be temporarily copied to all connected Slaves.

Runs on 2 AA Alkaline Batteries
As MCR-4V is battery operated, it is possible to measure and record even when electricity is unavailable. USB power can also be used.
Recording Interval as short as 2 msec / Resolution of 10 µV

Quick and precise measurements are made possible with a shortest recording interval of 2 msec and a minimum voltage resolution 10 µV. Select from two methods to record data: instantaneous value or average value.

The shortest possible recording interval depends upon the number of channels being used.

Logging Capacity of 480,000 Data Readings
When recording with one channel, up to 480,000 data readings can be recorded; perfect for recording over long periods of time.
Use of SD Memory Card for Easy Data Transfer to PC

Besides using a USB connection to directly send recorded data to a PC, it is possible to use an SD memory card to transfer data from a logger to a PC.

Operation Confirmed SD Memory Cards

  Manufacturer Manufacturer Part No. Memory Size Class
Lexar LSD32GCTBNA400 32 GB 10
  • SDXC memory cards cannot be used.
  • To prevent data loss in Endless mode, it is possible to make settings to automatically export the data to be overwritten to the SD memory card each time the internal memory reaches full.
Use of Trend Graph for Checking Data in Real Time

It is possible to view data as it is measured in real time on the LCD display.

Electrical Isolation between Channels
Channel isolation makes it possible to measure signals of different potentials.
Scale and Unit Conversion
It is not only possible to view voltage measurements as they are, but also change the scale and unit of measurement for each channel for recording and viewing.
Easy Touch Panel Operation
Designed with an easy-to-use touch panel for carrying out operations such as changing various settings.
Handy Preheat Function

Save battery power by using this function to supply power only to the sensor that is being used for recording.

  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 measurement interval and 50-60 Hz filter setting. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life.
