ES51932
22,000 Counts Auto DMM
1.4 Current measurement for clampmeter
ES51932 has 2 automatic and 4 manual current measurement modes for clampmeter.
The following table summarizes the full-scale range of each mode. When ES51932
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
ES51932 operates in the manual mode1~4, It takes high input from ADP, low input
from SGND and reference voltage from VA+ and VA-.

Note:
1. Connect VBAR to V- will disable the “µ2” / ”m2” symbol on LCD panel.
2. In DC current modes for clampmeter, ES51932 provides Zero function for offset removing.
