1.4. Current Measurement For Multi-meter
ES235 has 3 automatic current measurement modes for multimeter. The following table
summarizes the Full-Scale range of each mode. When ES235 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.

Note:
1. Connect VBAR to V- will disable the “µ₂” / ”m₂” symbol on LCD panel.
2. Connect SEL1 to V+(or Floated) or V- (or DGND) will set maximum readings of input for Automatic3 mode.

1.5. Current Measurement For Clamp-meter
ES235 has 2 automatic and 4 manual current measurement modes for Clampmeter. The following
table summarizes the Full-Scale range of each mode. When ES235 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.
