As with the zero point, if the external
reference matches the default span value,
simply press ent. Otherwise, key in the
current value of the external reference, then
press ent. After pressing ent, the display
reading should immediately adjust to reflect
the new calibration point. Pressing esc
instead of ent at this point aborts the
operation and returns the operator to the
calibration prompt.
9. Steps 4 - 8 are required only once. They
may be repeated as often as necessary
while in calibration, but only the most
recent point will be saved on completion
of calibration.
10. To permanently store the results of the
calibration press ent, and the unit will
prompt Enter to accept Calibration.
Simply press ent again to save the
