The metering inputs (MEXM-1 only) can be configured independently for any of the following input voltage ranges: ±2.5V, ±5V, ±10V, ±25V and ±50V. The voltage range selection is controlled through the DavLink software.
Caution: Do not exceed the voltage scale limits set for each metering input to prevent saturation of the internal amplifier.
Metering inputs are bipolar and have a minimum input impedance of 1M Ω . A detailed schematic is given in the image below.
