2.Above specification from 22nF to 2.2uF ranges are specified under REL mode. The
reading is calibrated to zero by relative function, when input is floating.
Function Description
1. Operating Modes
1.1 Voltage Measurement
A re-configurable voltage divider automatically provides a suitable range in voltage
measurement mode. The following table summarizes the full-scale ranges in each
configuration.

Note:
1. 220.00mV range is independent and manual mode. The input pin is different from other voltage
ranges.
2. If VST is set to V- level, the auto range mode will start from 220.00V range. 2.2000V – 22.000V
ranges only exist in manual mode.
