APPLICATIONS
Permanent Storage of Calibration Constants Also, constants for uncalibrated ranges are derived at this
point.
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 If the calibration jumper is in the disable position, NVRAM
off. For calibration to be permanent, you must perform
storage will not take place, and the following message will
NVRAM storage. Once all points have been calibrated, be displayed briefly:
press PROGRAM SELECT to exit the calibration program.
Assuming that the calibration jumper is in the enable posi- Out
tion (paragraph 5.3.1), calibration constants will be stored
in NVRAM, and the following message will be displayed
briefly:
Only changed constants are affected with uncalibrated
ranges unaffected. The new calibration constants will be
star used by the instrument until power is turned off. Tem-
porary calibration is denoted by the flashing exponent
decimal points.
