[Or. pH] = overrange pH
[Or. mV] = overrange mV
[Or. µS]
= overrange µS
[Or. MS]
= overrange mS
[Or. OhM] = overrange Ω
[Or. °C] = Overrange °C
[Or.PPt] = overrange ppt (TDS)
[Or.SAL]
= overrange salinity
[no dAtA]
= data-logging memory empty
[not.CAL]
= calibration procedure interrupted
[Err.SLP]
= slope not within 80...120 %
[Err.pHo] = ISO pH not within 6...8 pH
[Err.cc]
= cell constant not within 70...130% of the nominal value
[Err.CAL]
= calibration error
[Err.COd]
= invalid code
[Err.COM]
= general communication error
[Err.MEM] = fatal memory error; have your instrument serviced!
[ILLEGAL] = an unauthorised person has failed to repair the unit; warranty is
elapsed from now on!
The pH electrode should be connected to the coaxial pH connector. The mV
electrode should be connected to the coaxial mV connector. If separate electrodes
are used, connect the reference electrodes to the REF. terminals. Connect a
conductivity cell to the coaxial EC input. Automatic temperature compensation and
temperature measurements are possible by plugging a Pt1000 thermocompensator
into the °C terminals. Without compensator, the manual temperature compensation
is automatically switched on.
A recorder can be connected to the red (+) and black (-) REC terminals. Use only
laboratory recorders with a high input impedance!
A standard RS232 output terminal (DP9) is provided for interfacing the instrument
with a printer or computer (using the optional AK2310 cable). Data is sent in the
ASCII code at a BAUD rate of 150...4800 bps (8 bit, no parity, 1 stopbit).
