Hi Support-Team.

I have this item:
<h1 id=”title” class=”a-size-large a-spacing-none”><span id=”productTitle” class=”a-size-large product-title-word-break”>Charge-Discharge Multi Meter, DROK 0-120V 100A DC Voltmeter Coulometer, Mobile Phone APP Control LCD Battery Monitor Volt Amp Temp Power Capacity Timing Monitor for RV, Boat, E-Bike</span></h1>
It did work correctly for a few months, but after a while the red VCC voltage signal to the current shunt amplifier alternates between two voltages. This causes the signal from the shunt to vary as VCC varies. This leads the meter to show two different incorrect current values as the voltage goes up and down. It spends about 3.6 seconds at 5.6v, then 7 seconds at 6.0v, then repeats this pattern forever.

Help! What is this VCC signal supposed to be? Why is it alternating like this?

I have reset the settings on the meter, no change in behavior.

Hello,

Sorry, we are not sure the  VCC voltage signal you mean. Do you mean the votlage reading changes between two values?

If possible, could you please show how it is by video?
