As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example:
ABS plastic contains styrene
PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
electrolytic capacitors can contain Ethylene glycol
Brass can contain Lead
flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
Aluminum alloys can contain Chromium
To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
This is a great little panel meter, which I bought for a bench top power supply. It works good, except when there is appreciable noise on the power supply. I ran into this when testing the MPJA Boost Converter, 34904 PS. This converter generated a large amount of noise on the output, > 0.5VRMS at 15.4VDC @5.5A. For some reason the noise caused the panel meter display to blank. For this reason I gave it a 4 rating.
When tested with a good i.e. low noise 12.3VDC power supply, the display worked fine.

very low ohm sense resistor
The sense resistor for the current is on the order of .01 ohms so even at 10 amps there will not be an appreciable voltage drop. I wish this meter functionality came in a case that mounts in a round hole.
Works well, can be calibrated
I bought two units and compared their readings to a Fluke 3.5 digit multimeter. The readings were close, but I was able to adjust them to match the Fluke. The adjustments are two small potentiometers near the connector. The one labeled VR adjusts voltage and IR adjusts current. The only down side is that the display doesnt light up for input voltages less than 4.5 volts, but that is clearly stated in the specifications. I like this meter and recommend it.
