CALibration Command Subsystem
The CALibration command subsystem is used to zero and calibrate the U8480
Series.
The numeric suffix of the CALibration command (CALibration1) refers to Channel
A.
– Zeroing and calibration of the U8480-Series is recommended:
–When a 5
°C change in temperature occurs
– When connection to the U8480-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 U8480 Series to continue parsing and
executing subsequent commands while it is still executing.
