0 CALibrating This is a summary bit for the Operation CALibrating Register.
• SET: At beginning of zeroing (CALibration:ZERO:AUTO ONCE) and at the
beginning of calibration (CALibration:AUTO ONCE). Also for the compound
command/query CALibration[:ALL]?, this bit is set when sensor zeroing
begins.
• CLEARED: At the end of zeroing or calibration.
4 MEASuring This is a summary bit for the Operation MEASuring Register.
• SET: When the power meter is taking a measurement.
• CLEARED: When the measurement is finished.
5Waiting for
TRIGger
This is a summary bit for the Operation TRIGger Register.
• SET: When the power meter enters the “wait for trigger” state.
• CLEARED: When the power meter enters the “idle” state.
10 SENSe This is a summary bit for the Operation SENSe Register.
• SET: When the power meter is reading data from the power sensor’s EEPROM.
• CLEARED: When the power meter is not reading data from the power sensor’s
EEPROM.
