🔍 Measure with Confidence: Your Go-To Gauge for Precision!
The DROK® 0.28'' LED 4 Digit Digital Voltmeter Ammeter Gauge is a high-performance measurement tool designed for accurate voltage and current readings. With a measurement range of DC 0-33V and 0-3A, it features a dual display for simultaneous monitoring, voltage compensation for precise results, and operates on a power supply of DC 3.5-28V. Ideal for both professional and DIY applications, this meter is a must-have for anyone serious about their electrical measurements.

Very nice, inexpensive mA & VDC digital meter
I'm using the meter to measure a 4-20 mA loop. This meter works within my requirements. (I checked it via a Fluke 87. This meter was within 0.02mA.) For my go/no-go testing, this was a very good alternative to the very pricey Fluke. As other users have stated, the wiring diagram/connection diagram leaves something to be desired.

inexpensive and accurate
seems accurate, nice display. it can be very challenging to make this work. there is no diagram given and no examples. I'm reasonably good with these type of things but it took me a few tries to get it to work in my circuit

Beware
No instructions. Impossible to know if it’s connected properly.

Fairly accurate, no calibration
Tested up to 3A on a resistive load. The current measurement accuracy is quite good, being only +\- 0.005 A (5mA) different from my multimeters. The voltage measurement is less good, being anywhere from 0.05V (50mV) to 0.08 (80mV) higher than either of my two multimeters. The rated accuracy is 10mv, so that’s not great. A calibration or adjustment option would have been nice to set this, but no such option seems to exist. It has a push button, but it’s not clear what it does and pressing it doesn’t seem to do anything.

V/I small meters give continuous battery status
This meter combo was ideal to monitor the battery that powers my telescope during viewing sessions. When the voltage approaches 10.5 V I know I only have about 15 minutes before ‘shutdown’. The current meter let’s me know if all is well with the electronics, motor drives, dew heaters, etc.

These seem to work fine.
