MEASUREMENT

5.1

Display in Measurement mode

When the controller is initially powered on, it automatically enters into the Measurement mode after
the large dual LCD displays all segments briefly.
The upper display shows the measured Conductivity value, while the lower display shows the
temperature value. Annunciators at the right side of the display indicate whether the controller is set
for µS or mS measurement. Similarly annunciators or icons at the top or left side of the display shows
the current status of controller, e.g. "HOLD", "SETUP", "MEAS", "CAL", "READY", etc.
5.1.1

Check electrode performance

To read current electrode slope and offset values without changing them:
1) Press the CAL key followed by the ENTER key without adjusting the security code (leave code at
"000"). The upper display shows the condition of the probe. The lower display reading shows the
temperature reading.
Note: If security code is changed to a value other than "000", pressing the ENTER key will return
to the Measurement mode, without displaying electrode information.
2) Press the ENTER key a second time to return to Measurement mode.
5.1.2

Checking set points

To read current set point values without changing them:
•
Press the RELAY Selection (Rel A / Rel B) key. The upper display shows the set point for
Relay A; the lower display shows "SP1".
•
After two seconds the upper display shows the set-point value for Relay B; the lower
display shows "SP2".
•
After an additional two seconds, the controller returns to the Measurement mode.
