Measuring High Voltages - Radio Shack 22-218 Owner's Manual

Measuring High Voltages

When you measure voltage in a high-voltage circuit, do not try
to position both probes at once. Clamp one of the probes to
the circuit's neutral or ground lead using a Radio Shack insu-
lated slip-on alligator clip (Cat. No. 270-354). Then probe for
voltages with the other probe. This helps prevent you from ac-
cidentally touching a hot wire.
