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.
How to verify the detector voltage of SPY 790 Security Sensors?
To verify the voltage of your SPY Security Sensors detector, do not use a regular multimeter as it can be damaged and isn't rated for high voltages. Instead, use a SPY JM, rated for 7 kV DC and 35 kV Peak (crescent) on Pulse DC, or a SPY PJM, which can measure up to 20 kV.
What to do if the battery doesn’t seem to be working well with SPY Security Sensors?
If the battery of your SPY Security Sensors doesn’t seem to be working well, use a multimeter to measure its voltage right after charging. It should read 13.0 Volts or higher. If it has been sitting for several hours, a voltage as low as 12.3 Volts is acceptable. If the voltage is lower than 12.0 Volts, the battery may need replacement. Try testing with a different charger if possible.
What to do if my SPY Security Sensors holiday detector turns off while in use?
If your SPY Security Sensors holiday detector turns off while in use, it might be because the battery voltage has dropped below the required level. Try charging or replacing the battery. You may also want to test the battery.
How to fix SPY 790 Security Sensors holiday detector that will not detect holidays?
If your SPY Security Sensors holiday detector is not detecting holidays, you can try the following: * Check Ground Connections * Adjust Travel Speed * Perform Field Calibration * Conduct Detection Testing * Set the Minimum Voltage * Check the Detector Ground Connection * Check the Electrode/Wand Connection
