1.2 Current Measurement

1.2.1 For multi-meter application

ES51927 has 2 automatic and 1 manual current measurement modes for multi-

meter. The following table summarizes the full-scale range of each mode. When

ES51927 operates in the current measurement modes for multi-meter, it takes

high input from pin IVSH or IVSL, low input from pin SGND and reference

voltage from pin VR.

1.2.2 For clamp meter application

ES51927 has 2 automatic and 4 manual current measurement modes for Clamp

meter. The following table summarizes the full-scale range of each mode. When

ES51927 operate in the automatic mode1&2, it takes high input from

IVSH/IVSL (higher range/lower range), low input from SGND and reference

voltage from VR. When ES51927 operate in the manual mode1~4, it takes high

input from ADP, low input from SGND and reference voltage from VA+ & VA-.
