CALibration:STORe < type >
constants into Flash Memory (Electrically Erasable Programmable Read Only
Memory). When type=ADC, the module stores its A/D calibration constants as well
as constants generated from *CAL?/CAL:SETup into Flash Memory. When
type=TARE, the module stores the most recently measured CAL:TARE channel
offsets into Flash Memory.
Note
The HP E1415's Flash Memory has a finite lifetime of approximately ten
thousand write cycles (unlimited read cycles). While executing CAL:STOR
once every day would not exceed the lifetime of the Flash Memory for
approximately 27 years, an application that stored constants many times
each day would unnecessarily shorten the Flash Memory's lifetime. See
Comments below.

•
The Flash Memory Protect jumper (JM2201) must be set to the enable position
before executing this command (See "Disabling Flash Memory Access
(optional)" on page 25.).
•
Channel offsets are compensated by the CAL:TARE command even when not
stored in the Flash Memory. There is no need to use the CAL:STORE TARE
command for channels which are re-calibrated frequently.
