Drok dc 0-300V 200A – Highly Inaccurate Amp Readings

Forgive me for posting again, but I am unable to email the requested files. I have the DROK DC 0-300V 200A STN LCD Display Digital Multimeter Panel with Hall Sensor, SKU 2001712003. I have hooked the meter up according to the supplied directions, making sure to zero out the amp readings with NO LOAD. However, using a 13.8 volt power supply, that puts out a maximum of 12 amps, the meter shows wild readings up to 90+ amps. This is impossible as the load I’m using is only capable of pulling a maximum of 10 amps and the power supply is only capable of producing 12 amps. I’m assuming I purchased a faulty meter? Any suggestions would be great.

Image 1 shows the correct readings with very little load:

Image 2 shows the incorrect readings when a load of 10 amps is applied (It shows around 110 amps!!!):

Hello Eric,

From your picture, we find voltage reading also change  along with current various. Did you try to check the actual curent with other meter ?

Or would you like to test other load?

Best regards.

Yes. I have a non-panel type amp/volt meter and I checked. That meter showed 13.8 volts and 9.5 amps being used. I have tried your meter with two different power supplies, the one in the picture and a server power supply, but doesn’t work. Today, I hooked up a separate power supply for the meter, just in case there was some type of feedback, and it was still doing the same thing.

With that said, I do think that your suggestion wasn’t the most helpful. Commonsense tells me that a 12 amp power supply, with a 15 amp fuse, is incapable of producing 100+ amps. In addition, a 10 amp radio would literally explode of it pulled 100+ amps.

So, if you have any helpful suggestions, I’m all ears. Otherwise, I’ll return the product and go with a different company.

I purchased one of these DC0-300 200A LCD digital voltage amperage meters with the Hall effect sensor but have no operating instructions. Can you send me a PDF file that shows how to setup and program this unit to monitor a 200AH battery bank?
