async perform_zero_calibration(mode=None, auto=None, set_range=None, integration_time=None)

This enables the zero check and sets the mode and range before every measurement.

Parameters:

modestr | None

Mode of measurement, CURR, CHAR, VOLT, RES

autobool | None

Whether or not in auto range

set_rangefloat | None

async start_scan(group_id=None)

Start storing values in the Keithley electrometer’s buffer.

Parameters:
