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.
|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.
|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.
|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.
|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.
