Description

MCR series loggers are 4-channel battery-operated loggers. The MCR-4V is a voltage logger which can measure up to 24V.

With multi-channels and a large internal memory (up to 480,000 readings per unit), the MCR-4V is perfect for measuring voltage and current signals at various spots for long periods of time. Moreover, by using an SD card and the “Auto Data Export” feature recording can be carried out, even when using short recording intervals, over longer extended periods of time.

MCR-4V loggers can operate on battery or USB power. Data can be checked on-site from the loggers’ LCD trend graph. Data downloaded to your PC can be viewed and analyzed with our Windows-compatible software “T&D Graph.” It is possible to connect up to four loggers, including T&D’s MCR-4TC temperature data loggers, allowing for up to 16 channels of data. This coupled with the fact that the loggers are equipped with an SD memory card slot means they are perfect for use in various experiments with large quantities of data and for tracking frequent changes in voltage and current.

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.
