The meter that I received was not the same as advertised. Only had current adjustment pot! The meter read voltage and current but the current reading was off by 1 amp at 12 volts (Fluke amp meter). When I tried to adjust using a pot adjusting screwdriver the meter went to reading a dim 32 volts and one amp no mater what voltage was applied! Have tried to contact seller but no response. So much for customer service.

Really surprised for the money. Needed to make a quick and dirty power supply and used this meter for it. Voltage is right on the money…Scope says 14.25 volts and meter shows 14.2. Close enough for me!Have only tested the current to a few amps so far but is also right on the money. The only thing I’d say about that part is that it’s a little slow on the sensing side and takes a second to settle in on the current reading.Good value otherwise and works exactly as intended and as I needed!
