PARAMETER SETTINGS

• Once the parameter code (and password if

needed) has been entered, the current
value of the selected parameter will be
displayed on the primary LCD and the
parameter code on the secondary one. The parameter or a part of it
will blink (e.g. only the hour blinks if time has been selected).

• Enter the new value using the arrow keys.

• If there is another part of the parameter to be set (e.g. minutes

for the time), press DISPLAY to gain access and then enter the
new value using the arrow keys.

• Press CFM to confirm the value.
• If the entered value is not acceptable, the "WRONG" indication

will be displayed for a few seconds and then the meter will ask for
a correct value.

• If the confirmed value is accepted, the meter will pass to the next

parameter (asking for the password if it is protected).

Note: If (ALT+) SETUP are pressed before parameter value confir-

mation, the meter will not update the parameter and after
escaping will ask for a new setup code.

The following table lists the setup codes along with the description of the
specific setup items, their valid values and the factory settings (default):

parameter using the

key.

display "PAS" and the password must be entered to proceed.
Otherwise, the current parameter value will be displayed.

PASSWORD PROTECTION

Setting of time, date and calibration alarm time-out are password
protected and the user will be asked to enter the password to change
these parameters. After code confirmation the upper LCD will display
"0000".
• If password is set to 0000 (factory setting), just press CFM to

confirm.

• If password is set to a value different from 0000, enter the

password with the up and down arrow keys and then press CFM
to confirm.

• If the password is not correct, the meter displays the "WRONG"

indication and asks for the password again.

• If the password is correct, the meter provides access to the

parameter.
