The CVM is a high-precision 1 channel voltage measurement module and the base module for various expansion boards. Communication and power supply via USB. Furthermore, the PC ground is galvanically isolated from the analog ground.
Voltages in the range 0 V to + 26 V with 4 mV resolution with a typical accuracy of +/- 0.02 % at 23°C can be measured.
There are 2 operation modes: 1st query voltage, 2nd cyclic auto transmit voltage. Other operation modes, such as voltage monitoring (error on request) and a master-slave mode for multiple modules to synchronize mode 1+2, are available as optional modes.
The CVM can be equipped with up to 4 expansion modules.
