VL-DCVC – Voltage & Current Inputs, Range Programmable
Besides the on-board thermistor channel, the VL-DCVC logger has seven external voltage and
current channels. The first four external channels are used to measure single-ended voltage
maximum of 20 VDC and the remaining three external channels are used to measure single-
