- If the batteries are fine, try a different set of batteries.
- If the EMF450 still does not turn on, contact Extech customer support for assistance.
Issue: The EMF450 is not reading any EMF levels. Solution:
- Make sure that the EMF450 is in the correct mode. The EMF450 has three modes: AC, DC, and Frequency. Make sure that the mode switch is set to the correct mode for the type of EMF level you are trying to measure.
- If the EMF450 is in the correct mode, try moving it to a different location. Sometimes, EMF levels can be very low, and you may need to move the EMF450 closer to the source of the EMF to get a reading.
- If you are still not getting a reading, contact Extech customer support for assistance.
Issue: The EMF450 is giving inaccurate readings. Solution:
- Make sure that the EMF450 is calibrated properly. The EMF450 comes with a calibration certificate, which shows the correct readings for the EMF450. If the readings on your EMF450 are different from the readings on the calibration certificate, then the EMF450 may need to be recalibrated.
- If the EMF450 is calibrated properly, then try cleaning the sensor. The sensor on the EMF450 can become dirty over time, which can affect the accuracy of the readings. To clean the sensor, use a soft cloth and some rubbing alcohol.
- If you are still getting inaccurate readings, contact Extech customer support for assistance.
