Meter Voltmeter DC 0-5V, 0-15V Dual Scale
This meter is designed to measure DC voltage.
Before measuring, please make sure this meter is put on a horizontal flat and screw ZERO-ADJUST knob to make the pointer to ZERO point unless the pointer is originally at ZERO point.
Choose the proper measuring range, be sure the voltage to be tested is not more than the range settled on the meter.
Connect this meter parallelly into circuit. Make sure the positive and negative terminal are connected correctly.
Read voltage value from the analog meter.
