Wiring: Voltage and current measurement

Wire the voltage inputs of the channel voltage in parallel using the corresponding shunt

resistor when measuring current. Bridge the channel input terminals with the adjacent

connector terminals.

Example: You configure channel 0 for current measurement by bridging terminals 22 and 2,

and terminals 23 to 3.

At the channel configured for current measurements, connect the shunt resistor to the

adjacent channel terminals in order to achieve the specified precision.

①
