4. Operation
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.
To modify this configuration see page 17.
