Setting the password
General notes:
The multifunction meter can be protected against unintentional changes by setting a 3-digit
password. By using the password unwanted programming access can also be prevented.
If the 3-digit numerical password is set the setup mode can only be accessed when the password
is entered and confirmed by pressing the T3 (OPT) key. If the password is correct the setup menu
is displayed.
If the password is incorrect the device returns to display mode.
The factory preset is …000ˆ. If the password is set to …000ˆ the MFA 2001 does not request a
password and jumps directly to the setup menu.
For your attention !
If the user password is lost (except …000ˆ) the device can only be reset by the manufacturer.
Setup:
Activate the setup menu („PAS ADJUST…) by pressing the T3 key (OPT).
The setting „000.… is displayed with the first digit flashing.
With the T1 ( ‡ )
key the value can be increased starting at …0ˆ through to …9ˆ. To access a lower
value press the T1 ( ‡
)
key past …9ˆ to start again with …0ˆ.
Press the T2 ( ‚ ) key to access the next digit. The digit starts flashing. To change the value press
T1 ( ‡ )
key.
The process is completed by pressing T3 (OPT) key. The setup menu is displayed.
Store the set parameters in the flash memory by pressing T4 and exit setup mode.
