Passcode
The " Passcode " function can be used to change the passcode as
well as to activate or de-activate the menu function block.
The " lock " function is used to prevent access to the Multi-PID 2’s
sensitive options. Sensitive options are those which can affect the
Multi-PID 2’s readings. If any of these functions is selected when the
instrument is locked, the Multi-PID 2 will prompt you to unlock the
instrument before you can access the functions.
The " unlock " function is used to obtain access to the Multi-PID 2’s
sensitive options.
The " change " function can be used to change the set passcode.
The unit always has a passcode in force. When shipped from the fac-
tory, the code is 0000.

you cannot remember your passcode once the instrument is lok-

contents. Unlocking the instrument without a password is
accomplished by doing a reset or “cold start”. To do the reset,
hold the middle-upper key while turning the instrument on with
the on/off key.
