CALibration Subsystem

CALibration Subsystem
The CALibration command subsystem is used to zero and calibrate the U2040 X-Series.
The numeric suffix of the CALibration command (CALibration1) refers to Channel A.
Zeroing and calibration of the U2040 X-Series is recommended:
– When a 5°C change in temperature occurs
– When connection to the U2040 X-Series is established
– Every 24 hours
– Prior to measuring low-level signals.
The following CALibration commands are overlapped commands:
– CAL:ALL
– CAL:AUTO
– CAL:ZERO:AUTO
– An overlapped command allows the U2040 X-Series to continue parsing and executing
subsequent commands1 while it is still executing.
