Otherwise the meter will be burned out. Package Included: 2* 0.28" Digital Voltmeter Ammeter DC 100V 10A Blue + Red Dual LED Display 2* Set of two wires

Review: Good Little Meter - These are great little meters. I have 4 of them that I used to moniter power supply outputs and they work great,
Review: Poor documentation. Works well when all is corrected. - I am an electrical engineer with extensive experience in digital electronics. I used two of these meters to replace defective analog meters in a power supply. I found the connection diagram easy to use but both meters in the 2-pack are showing incorrect voltage and current readings. After much searching for documentation I discovered that when connected to a power supply using that power supply to power the display that the thin black wire must be left unconnected. With that fix the two calibration adjustments worked.
