Description
CALibration Subsystem:
ACAL:
Prepare 2182 for ACAL.
Perform full ACAL (100V and 10mV).
Perform low level ACAL (10mV only).
Exit ACAL (see Note).
Read the internal temperature (in °C) at the time
of the last ACAL.
SENSe Subsystem:
Measure the present internal temperature (in ˚C).
SYSTem Subsystem:
Enable or disable Front Autozero.
SYSTem Subsystem:
Enable or disable Autozero.
SYSTem Subsystem:
Enable or disable line cycle synchronization.
SENSe Subsystem:
Enable or disable Low Charge Injection Mode for
Channel 2 (see "Pumpout current (low charge injection
mode)" for details).
