Why aren't holidays being detected with SPY 790 Security Sensors at the required voltage?
If the testing documentation requires a specific voltage, use that setting. Environmental conditions like humidity and temperature affect the voltage needed to spark across a holiday. Calibrate the SPY Security Sensors in the field daily or as conditions change to ensure accurate holiday detection.
What to do if I need to check the pipeline with SPY 790 Security Sensors but the pipe is wet or it is raining?
Holiday detection with SPY Security Sensors cannot be done in the rain because it will conduct back to ground, causing false readings. While light moisture might allow for use, it's highly recommended to ensure the pipe is dry and clean before testing. Prioritize safety and use appropriate safety equipment in wet conditions to prevent electric shock.
Why does my SPY 790 holiday detector turn off while in-use?
If your SPY Security Sensors holiday detector turns off while in use, it might be due to low battery voltage. Ensure the battery is fully charged before use. You can also test with a second, charged battery to see if the issue persists. For more in-depth troubleshooting, refer to the Battery Troubleshooting section.
How to fix SPY Security Sensors that will not detect holidays?
If your SPY Security Sensors holiday detector is not detecting holidays, perform a field calibration to adjust for environmental factors. Use the NACE equation to set the minimum voltage. Pass the detector over a known holiday, increasing the voltage until it's detected. Note that the maximum voltage depends on the coating manufacturer, typically ranging from 400 to 1000 Volts/mil for new coatings. Also ensure ground cable and electrode wand are correctly inserted.
