Current Measurement with Current Clamp Sensor
& Shunt Resistor
SR9800
Voltage/Current Transformer Output
When a current clamp sensor CP1800 is connected to the system
multimeter (mA/A input) via shunt resistor SR9800 (see Accesso-
ries, section 10.5) , all current displays appear with the correct
value in accordance with the selected transformation ratio. The
only prerequisite is that the current sensor is equipped with at least
one of the below listed transformation ratios, and that the ratio has
been previously selected in the following menu (
