Troubleshooting: Pointek CLS500
If you are unable to change settings:
•
Check that keylock level (menu 1F) is set to 0: the display should read PL = 0.
•
Check that menu 01 is set appropriately: If Pv = 1, changes can only be made via
HART.
If you can change settings:
•
Reset menu 12 to factory settings: press both buttons, and the display should
read FAC A when buttons are released.
If the LCD displays a negative reading, typically around 100 pF, this often indicates a short
circuit in the probe assembly:
•
Check the enclosure and make sure no water has got in.
•
Check that all the connections in the probe assembly are solid.
