Notes

(1): The calibration password allows only calibrations, while

the general password allows everything (including calibra-

tion). Obviously, the general password and the calibration

password cannot be viewed among other items when the

“SETUP” key is pressed without entering the right general

password. The instrument is sold with a “0000” general pass-

word.

(2): When a wrong setup value is confirmed, the instrument

does not skip to the next setup item, but remains in the cur-

rent item displaying a blinking “WRONG” indicator till the

parameter value is changed by the user (the same thing hap-

pens also for the setup code selection).

(3): See the “Temperature compensation” subsection for more

details on how the Automatic temperature compensation and

Manual temperature compensation work.
