Calibrating and Verifying Performance
Chapter 4
CALibration:TEMPerature?
CALibration:TEMPerature?
performs the temperature-related calibration
procedures. Calibration is performed assuming the mainframe is in these conditions:
no modules loaded, mainframe at a steady state temperature in a constant
temperature environment (fan switch set to FULL for at least ten minutes). This
means that this command should always be issued through the RS-232 interface.
Calibrations performed are:
•
Calculated A/D offset and gain for each temperature sensor. Externally
measured temperature previously reported to the enhanced monitor through
CAL:VAL:TEMP are used for these calculations. Flag any sensor varying
more than ±2 degree off expected.
Returned Data
Comments
•
It is advisable to make the calibration value measurement and provide it to the
enhanced monitor via CAL:VAL:TEMP immediately prior to using this
command. Old values will be used otherwise. If you want the calibration
routine to calculate a temperature calibration value you MUST send a
CAL:VAL:TEMP -1 before every calibration command.
•
The calibration value (reported to the enhanced monitor with
CAL:VAL:TEMP) has a default value that will be used by the calibration
routine if no value is ever measured and reported to the enhanced monitor. See
CAL:VAL:TEMP for details.
Error Conditions
The following table lists the most common error conditions and causes. Error
numbers and corresponding messages can be found using SYSTem:ERRor? query.
Reset Condition
Calibration is not affected by reset. However, if a *RST is issued while a calibration
is occurring the calibration will be aborted.
