to the circuit and you should never verify the continuity of an object that is placed on a
conductive surface.
Safely Using the DVM-

Never use any DVM that is damaged or its probes are damaged.

Never measure voltages or amperages if it is raining or you are standing in water.

Always verify if power is applied to the test subject with a known good Voltage Checker
before you test it with your DVM.

Never measure continuity with power applied to the circuit.

Never hold a wire with power onto the probe with your fingers.

Never use both hands to measure a voltage, use a self sustaining connection like an clip to
maintain one of the probe’s connections and then use one hand with the other probe.

Never connect the AC Amp Clip to a powered circuit, always remove power, connect the
clip, and then turn the power on to measure amperage.

Never use a DC Amp meter function to measure AC amperage.

Always replace batteries and fuses with those specified by the manufacturer.

If your DVM gets wet, DO NOT USE IT!!
It is important that you understand what type and voltage you should expect. If you do not set your
voltmeter correctly, it will not read correctly. It is important that it is put in the correct measurement
mode you are intending to verify. Many times you can see what power is being supplied to a device or
refer to its label to verify how to set your meter.
