Below set-point control operation

Short the SET SELECT/COM connectors with

a jumper wire. The set contact relay will

close if the measured value is lower than

the set-point value and the SET ON LED

will be lit.

ALARM

Press the ∆AL key and the display will show the set tolerance for the

alarm.

Use a small screwdriver to adjust

the trimmer ∆AL until the de-

sired tolerance is displayed.

Example: If the set value is 200

µS/cm and a ∆Alarm of 50 µS/

cm is set, an alarm is activated

every time the measured value

is higher than 250 µS/cm or

lower than 150 µS/cm.
