In this video, I have reviewed the DS-VC288 panel mount voltmeter/Ammeter using the Siglent SDM3045X benchtop multimeter. The VC288 meter did not present acceptable readings, especially in the current measurement. It uses an LM358 Opamp which is not suitable for this purpose and it does not show a linear behavior. The SDM3045X multimeter was used as a reference. I have tested the voltage and current readings separately.
