Current Measurement For Multi-meter

ES237 has 3 automatic current measurement modes for multimeter. The following table

summarizes the Full-Scale range of each mode. When ES237 operates in the current measurement

modes for multi-meter, it takes high input from pin IVS, low input from pin SGND and reference

voltage from calibration scheme.

Current Measurement For Clamp-meter

ES237 has 2 automatic and 4 manual current measurement modes for Clampmeter. The following

table summarizes the Full-Scale range of each mode. When ES237 operate in the automatic modes

and the manual mode1~4, it takes high input from CLAMPin pin, low input from SGND and

reference voltage from VR_CLAMP.
