Permanent Storage of Calibration Constants
The procedures given in the preceding paragraphs will
temporarily store calibration constants in internal RAM
memory and will be lost when the instrument is turned
off. For calibration to be permanent, you must perform
NVRAM storage. Once all points have been calibrated,
press PROGRAM SELECT to exit the calibration program.
Assuming that the calibration jumper is in the enable posi-
tion, calibration constants will be stored in NVRAM, and
the following message will be displayed briefly:
Stor
Also, constants for uncalibrated ranges are derived at this
point.
If the calibration jumper is in the disable position, NVRAM
storage will not take place, and the following message will
be displayed briefly:
Out
Only changed constants are affected with uncalibrated
ranges unaffected. The new calibration constants will be
used by the instrument until power is turned off. Tem-
porary calibration is denoted by the flashing exponent
decimal points.
