Calibrating the Model 9100 at Target Values
10.3.4.1
The Calibration Screen
Pressing a Factor keys on the 'target selection' screen presents the 'Calibration' screen. The
resultant screen for Factor 1 of the DC Voltage,
±
0.32001V to
±
3.20000V hardware
configuration is shown below, using the default target value of -3.00000V. Note that the
output value of 1.00000V remains displayed, (this appeared on first entering Cal mode, and
was then used to place the 9100 into the correct hardware configuration). A smaller-sized
version of the selected factor's target value appears in the lower left corner:

OUTPUT CONTROL VALUE
CAUTION! Do not press the CALIB softkey while using the Calibrate screen unless
you are sure that you wish to perform an authorized recalibration of the selected hardware
configuration at the selected target value. To prevent accidental calibrations taking place
due to inadvertent use of the CALIB key, and for your own safety, it is best to carry out
all hardware configuration, target value selection and initial use of the calibrate screen
with the 9100 output OFF. If you accidentally press the CALIB key, or attempt a
calibration without first turning the 9100 output on, the following error message will be
shown:
Output must be ON for CAL
Under output-off conditions, the existing, stored calibration corrections will remain
unchanged.
