At start-up the display will show all
the used segments for a few seconds
(or while the button is held), followed
by the percentage indication of the
remaining battery life.

• After a few seconds “

Cond

” message

appears, the “ ” and “

WAIT

” tags will

blink on the LCD if probe is connected
to inform the user that the probe is in
auto-conditioning (automatic polarization)
mode.

• When this message disappears, the probe

is polarized and the instrument can be
calibrated.

• The meter is now ready to operate.

• If the probe is disconnected or broken, the

meter will display “

----

” and “

NO Probe

tag blinking. In this situation only SETUP
menu is available.

The auto-off feature turns the instrument off
after a set period (default 20 min) with no
button pressed to save battery life. To set
another period or to disable this feature, see SETUP menu on page 17.
The auto-off backlight feature turns the backlight off after a set period
(default 1 min) with no buttons pressed. To set another period or to
disable this feature, see SETUP menu on page 17.

PROBE POLARIZATION

The probe is under polarization with a fixed voltage of approximately
800 mV.
Probe polarization is essential for stable measurements with the same
recurring degree of accuracy.
