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.

+0 indicates a satisfactory calibration.
+1057 to 1069: bad front sensor in slot [result-1057]
+1070 to 1082: bad middle sensor in slot [result-1070]
+1083 to 1095: bad rear sensor in slot [result-1083]
•
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.

Calibration is not affected by reset. However, if a *RST is issued while a calibration
is occurring the calibration will be aborted.
CALibration:ALL?, CALibration:VALue:TEMPERature

Description
Probable Cause
The mainframe's power is off or command sent through
VXI commander.
Calibration was aborted by a device clear event or *RST
