      I can’t get the ohm meter to give me meaningful readings in any of the ranges below 1 Mohm. If I connect the ohm and common terminals to a 4.7 kohm resistor I get correct readings on the manual 10 Mohm and 1 Mohm scales. On any of the lower scales the value bounces around, eventually resting at around -7.8 ohms. Autoranging just gets me to the bad value more quickly. It doesn’t work any better for other resistor values. Volt and ammeter readings are fine.

      My meter is one of the versions that arrived with a dead battery, so I put in a new one. I did my best to deburr the connector, but I wonder if this is the cause of the problem. Otherwise I am using the latest iOS app. Any help appreciated.

      Well, I’ll answer my own question. The battery in the bad holder is down to .6 volts. I’ll give it a good deburring when I have time and inspect it with the microscope to be sure.

      Hi PJ,

      Glad you found the battery contact issue but I don’t think that would explain the behavior in the low resistance ranges. That sounds like a hardware defect. Email hello@moosh.im and we can try to work out a replacement.

      Could it have been a poorly seated input pin? After replacing the batteries, it is working normally again. I can’t think of anything else related to taking it apart that would fix it, except the batteries or poor contact with the ohms pin. I had tried a reboot previously and that didn’t fix it. If it acts up again, I will contact for a replacement.

      Sounds good, glad it’s working :)
