Questions and answers
I can't get a reading on the amperage setting. Is it possible batteries or user error. Sending a picture. Maybe wrong setting. Ty
The UEi DL579 may not be providing a reading on the amperage setting due to one of the following reasons:
1. Incorrect Connection – Ensure the test leads are properly connected to the correct input terminals for measuring current.
2. Blown Fuse – The internal fuse may be blown, preventing current measurement.
3. Single Conductor Requirement – When using the clamp for AC amperage, only a single conductor should be inside the jaws.
4. Battery Issues – Weak or dead batteries could affect the meter’s functionality; replace them if necessary.
5. Selector Dial Position – Ensure the rotary selector dial is set to the correct amperage measurement mode.
If these steps do not resolve the issue, further inspection or repair may be needed.
