3.3. Cell cables
Compensation of the cable length
To minimize the effect of the cable resistance in a conductivity measurement, the cable length is compensa-
ted by the 4-wire system. With the Pt 1000 temperature sensor, the cable resistance has little importance.
However, in order to reduce the resistance of the conductor to a half, 2 cables have been connected to
the ends of the sensor.

3.4. Protective wiring of switching contacts
Relay contacts are subjected to electrical erosion.
Especially with inductive and capacitive loads, the service life of the contacts will be reduced.
For suppression of sparks and arcing, components such as RC combinations, nonlinear resistors, series
resistors and diodes should be used.

4.2. Setting up
Connect the si629 C to mains. At power up the first time only the following screens will appear:
The instrument is already measuring conductivity, with the following factory settings:
• Temperature coefficient 2% / °C.
• Cell constant C=1 cm-1.
• Reference temperature, RT, at 25°C.
• Relay 1, limit activated at 1000 µS/cm, and deactivated at 800 µS/cm (measuring salinity, activated
at 1 mg/l and deactivated at 0.8 mg/l).
• Relay 2, cleaning during 3 sec each hour, with 5 sec of post-cleaning time.
• Alarm relay, activation after 10 min of reading out of limits.
• Current output 4 mA = 200 µS/cm, 20 mA = 2000 µS/cm (measuring salinity
4 mA = 0.2 mg/l, 20 mA = 2 mg/l).
• Current output with the instrument in “Hold” mode, 21mA.
• Data Logger deactivated.

When being in the gray zone, the instru-
ment is in hold state:
• Limit and cleaning relays are open.
(Alarm OFF).
• According to the configuration the cu-
rrent output is frozen at 21 mA or at the
mA corresponding to the last measured

to carry out the test.
To quit the hold state it is necessary to re-
