Calibration Mode Screen Softkeys
The following screen softkeys are active:-
Special
Accesses the Special Calibration menu so that you can perform the 'Chse
DAC' (Characterise Digital-to-Analog Converter) calibration operation,
which must be performed immediately before carrying out routine
recalibration of the Model 9100.
COLD
The Reference Junctions used in the Thermocouple Temperature function
JUNC
are housed in an external module, whose internal temperature is monitored
CALIB
automatically by the 9100. This facility permits the monitor circuitry to be
calibrated, while in use. The calibration is performed by measuring the
temperature of the reference junctions externally, then entering the measured
value via the front panel, or remotely via the IEEE-488 bus.
Factory
Accesses 'factory-set' calibration operations which can only be entered
use only
by a special password. These calibration operations only need to be
performed when the instrument is manufactured, or after certain types of
repair have been carried out on it.
STD CAL
Accesses the user control screens for routine external calibration of each
Model 9100 function which can be calibrated.
