To Next PageTo Next PageWhat to do if LED readouts are blank on Polatrak Measuring Instruments?
If the LED readouts are blank, verify the switch position (Forward: on, Rear: off). Also, check if the batteries are dead and replace them if necessary. In case the pressure housing is flooded, use a backup unit and return the faulty unit to Polatrak.
Why are the readings not steady on my Polatrak CP-Gun?
Unsteady readings on your Polatrak Measuring Instruments can be caused by several factors. First, check if the voltmeter batteries are low and replace them. Second, ensure good structure contact by re-stabbing to improve the connection.
What to do if both electrodes are reading low on Polatrak Measuring Instruments?
If both electrodes are reading low, the tip wire might be damaged. To resolve this, remove the probe element housing, unplug the tip wire, remove the nose cone, and inspect the tip wire. As a temporary fix, repair it with ScotchKote and order a replacement nose cone.
What to do if one reading suddenly reads less negative on Polatrak CP-Gun Measuring Instruments?
If one reading suddenly reads less negative, it could be due to a flooded connector. Inspect and check the connectors.
