765 Laboratory pH Meter
6
Operation
More detailed information on the indicated elec-
trode condition and the individual parameter evalu-
ations is given in chapter ”Diagnostics level” (see
Pg. 21).
Sensoface
®
was specially designed for monitoring
pH electrodes. Since ORP electrodes have com-
pletely different characteristics, they provoke
invalid Sensoface
®
displays. Therefore, you should
disable Sensoface
®
for ORP measurements.
Sensoface
®
display can also be degraded when
you use a pH simulator.
Power-on and start-up
Mains supply
The pH meter is designed for 230 VAC supply
(Option 363: 115 V AC). Connect the power input of
the pH meter to a mains outlet using the included
power cord.
If the pH meter is disconnected from mains, clock
and calibration timer are not affected (reserve
power approx. 1 year). Settings, calibration and
diagnostics data remain permanently stored.
Electrode connection
The pH meter can be combined with commercial
electrodes: with nominal zero at pH 7 and with
• standard coaxial plug to DIN 19 262 and/or
• 4 mm banana plug.
For special electrodes with differing specifications,
we offer Option 346 (nominal zero and slope of
electrode user defined).
