6.4.5. Making Measurements
Understanding Phantom Readings
In some DC and AC voltage ranges, when the probes are not connected to any circuit, the display might show a
"phantom" reading. This is normal. The meter's high input sensitivity produces a wandering effect. When you connect
the probes to a circuit, accurate readings appear.
Measuring High-Voltage circuits
When you use the meter to check a high voltage circuit, do not try to position both probes at once. Instead, clamp
one probe to the neutral or ground lead of the circuit (usually a bare, green, or white of the in AC wiring circuits) using
insulated slip-on alligator clips. Then probe for voltages with the other probe. This helps prevent you from accidentally
touching a hot wire because you need to concentrate on only one test probe.
WARNING! Never clamp onto a hot wire (usually red, black or blue in AC wiring circuits). If you clamp onto a hot wire
and touch the other probe, you could receive a shock.
AC/DC Voltage Measurement
Warning: Do not try to measure a voltage greater than 1000 Volts DC or 750 Volts AC. You might damage your meter
and expose yourself to a severe shock hazard.
Note: "OL" is displayed on the display when more than the maximum voltage (DC 1000/AC 750 Volts) is supplied. If
this happens, DISCONNECT THE PROBES IMMEDIATELY.
