Chapter 6 Proper Measurement
6.1 Wiring method
JK9306 series instruments provide four test wiring input terminals, namely high voltage end, low
voltage end, high current end, and low current end.
Because the voltage and current are floating inputs, there can be multiple combinations of test
wiring methods, and different applications can be connected to the corresponding test circuit.
Here are two recommended wiring methods for the measurement circuit.
Tip: Considering that the presence of distributed capacitance may affect the test, in order to
reduce the impact of distributed capacitance on the test circuit, it is recommended to make the
current test terminal as close as possible to the ground of the input source, that is, the current
terminal is connected to the Low-end.
