• A: Compared to measurement input range, higher measuring voltage needs a multiplier and
lower measuring voltage needs a shunts.
• Connect the separated power supply each.
• (-) terminal of the power and (-) terminal of measurement input are shorted.
In case of using same power supply, measurement error or overcurrent may occur.

• B: When measuring higher current than measurement input, use a shunt for DC current and
a current transformet (C.T) for AC current.
