Description

The TandD MCR-4V is a four channel battery operated voltage data logger. Up to 4 units can be coupled together making it possible to 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.

Using a USB connection, recorded data can be sent directly to a PC, or a SD card (not supplied) can be used. Data can also be viewed and checked on the handy LCD display.

The logger also features a handy preheat function – save battery power by supplying power only to the sensor that is being used for recording.

The MCR-4V is convenient for measuring voltage in electrical circuits, control devices and measurement instruments in factories, recording signals from actinometers, anemoscopes, rain sensors and CO2 meters. The unit can record output signals from a variety of sensors and analyzers.

  • *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.
