1 4mA or 0% calibration switch:
This switch calibrates 0% or 4mA level and
it also trims 4.0mA value in association with
switch 3 (decrease) and 4 (increase)
2 20mA or 100% calibration switch:
This switch calibrates 100% or 20mA level and
it also trims 20.0mA value in association with
switch 3 (decrease) and 4 (increase)
3 Digital Trim (decrease) Switch
4 Digital Trim (increase) Switch
Switch#4 also act as diagnostic switch
5 Range Switch select for 1500pF to 4200pF
1500pF is required for oil and water up to
2500mm probe. 4200pF is required for water
above 2500mm probe
Shown on the left is typical ON and OFF positions of
the DIP switches.
Always use a small screw driver to turn ON/OFF the
switches using pen and other method may damage the
switches.
