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.

660.0mV range only exists in manual mode when VST pin is kept floating or DGND.
If VST is set to V- level, the auto range mode will start from 660.0V range. 660.0mV – 66.00V
ranges only exist in manual mode.

1.1.1 CE selection
ES51967 has a CE selection feature archived by configuring a CESEL pin. If pin
CESEL is connected to V-, ES51967 will have a 610.0V overflow level in DC and AC
660.0V ranges. And the 1000V range will not occur anymore. If pin CESEL is
connected to DGND or floating, the ES51967 will have a 1010V overflow level in DC
1000V range and have a 1010V overflow level in AC 1000V range. The meter will
Show OL when the measuring signal reaches the overflow level. The configuration of
CESEL is listed below.
