Note While in the setup mode, if no activity is performed for about
5 minutes after entering the setup mode, the mode is auto-
matically exited and the instrument returns to the previous
mode.
The below table lists the setup codes along with the description of
the specific setup items, their valid values and whether the item is
present for ORP mode.
Titles in Italic character (e.g.. “SETPOINT 1 “) represent different
subgroups within the same group. The subgroup name (e.g..
“Set1”) is showed when entering the first item of the sub-
group. To scroll through subgroups, use the key.
Depending on the device model, some of the below items or
item values may not be available.

Otherwise, if a numeric value has to be entered for the
item, use the
æ or key to change the value of the blink-
ing digit and the key to cycle through the number’s
digits.
• Once a value is set, press the CFM key to confirm. The
instrument will turn to the next item and the new item’s
value will be displayed on the primary LCD.
• If a wrong value is confirmed, the
WRONG indicator starts blinking,
the new value is not accepted and
the instrument will not switch to the
next item until a correct value will
be confirmed.
• Instead of selecting the item manually, it is possible to cycle
through all the items of a selected group by pressing re-
peatedly CFM key. The procedure to modify the item’s value
is the same described above.
If the last item of the group is reached, by pressing the
CFM key again the primary display will show the group
name and it will be possible to change the group by press-
ing the
æ or key.
Note At any time for exiting the setup mode press the SETUP key. If
no modification has been confirmed, no setup item is
changed.
