Charge Sensor (CRG-BTA)
Troubleshooting
Confirm that the proper setting is chosen on the sensor box.
- Primary Test: After initial power up or whenever changing range setting, press the Reset button for a few seconds with the leads shorted together just to make sure all charge is depleted from the internal capacitor.
- Secondary Test: Are the readings imprecise? Be careful when handling the leads or you may alter the readings with stray charge. Refer to the sensor booklet for more tips on the proper handling and use of this sensor.
Note: This sensor was manufactured with three sensitivity settings until the last week of May, 2018. Since then, a model with only two sensitivity settings has been the shipping model. See SPECIFICATIONS.
