Hey all,
I started a thread in the Test Equipment forum that's evolved into a troubleshooting exercise. If anyone has any experience or insight with the Fluke 8808a or rebranded models of the same ilk, I'd appreciate any help you might be able to provide.
Here is the original thread:
https://www.eevblog.com/forum/testgear/fluke-8808a-question/Here is a summary of the behavior:
With a 9V battery fresh out of the box, here are the readings in each range (meter set to "slow"):
200mV: ~139.75mV
2V: 1.568V
20V: 4.59V
200V: 8.245V
750V: 8.25V
My Fluke 175 reads 9.15V from the same battery using the same probes.
The same deal for AC (Ranges are the same) with the probes mashed into an AC outlet:
200mV: ~55.18mV
2V: 0.48744V
20V: 0L (yay!)
200V: ~107.695V
750V: 109.52
My Fluke 175 reads 118.2V in the same outlet using the same probes.
I think this meter isn't measuring right at all. What started this all is the fact that it won't auto-range, which is apparent when I choose DCV, probe a 9V meter and it reads ~139mV without clicking or reporting 0L.
Voltage readings using my Fluke 175 while measuring a 9.17V battery:
I have the option of just returning it for a full refund, but now I feel like I'm on a quest. I'm sure you all know what that's like.
