NOTE: The correct load must be connected, even
if nominals are being loaded. Otherwise, the
VBASE check can cause a fault in RUN mode.
After a fully calibrated mode is entered, making a
change to any one calibration point will cause all
of the other points in that mode which have not
yet been checked to be declared uncalibrated.
Those points must then be calibrated prior to
returning the unit to service. This precaution is
taken on the assumption that if some part of the
circuitry has changed enough to justify adjust-
ment of one calibration point, then it is likely that
the other points have been affected as well.
4.6.2.3 Calibration Limits and Validity Tests
Each calibration value is based upon a VBase and
Waveform drive value to set the output power.
When the unit is calibrated, the VBase or
Waveform value requested for the mode is adjust-
ed for the correct power output at that calibration
point. The VBase or Waveform is tested to be
within +25% of a nominal value. If the value is
within the range, the calibration value is stored as
calibrated, otherwise, it remains uncalibrated. At
the same time, a separate VBase and Waveform
average voltage is taken and stored to correspond
with each calibrated point for failure analysis.
If a PAd calibration point is out of range, due
either to a circuit fault or connection of an incor-
rect resistor to the return electrode terminals,
both PAd calibration points will be declared
uncalibrated. Attempts to store an out of range
value in this mode will result in a Key Error alarm
tone.
When the “STORE” Key is pressed to exit a
Calibration mode, the unit first checks for any
uncalibrated points in that mode. If any exist,
then an Err 10.X code is displayed where the “X”
corresponds to the mode that is not calibrated.
See Appendix A. The values of all of the points
remain as they were at the time of exit, eliminat-
ing the need to repeat the adjustments that were
already made.
Pressing the “STORE” Key again will restore the
menu, and the menu display for the partly cali-
brated mode will flash. The calibrated and uncal-
ibrated status for all points in that mode is pre-
served while in CAL Mode, so that when the
mode is reentered, it is necessary only to calibrate
the flashing points to fully calibrate that mode.
Because the VBase or Waveform drive values
increase steadily with increasing output power for
