DSN-VC288 DC 100V 10A Volt Amp Meter Dual Digital Display Module With BLUE RED LED Display VC288 DC 100V 10A Voltmeter Amperemeter With Cables
Due to the aging of the device and change of ambient temperature. The error becomes larger when measuring small current. Solution: When there is no load, short-circuit 2 pads of KEY and then power on, the module will automatically do zero calibration, after that shut off the module and cut the short circuit point.
The error becomes larger in whole measurement range Solution: When connecting load(half of the range is best), keep adjusting R7 until it displays the same value with the more advanced calibration source.
