8. When using the jaws to take a measurement, center a single conductor of a cable in the jaws and perpendicular to the jaws
to avoid false readings. When two or more conductors are in the jaws when an AC reading is taken, current flows in each
wire tend to cancel each other. Off center wires produce lower readings.
9. For reliable measurements, replace battery when the low battery symbol appears on display. See MAINTENANCE
instructions to replace battery.
10. Set function selector to OFF when not in use to conserve battery power.
3.2 VOLTAGE MEASUREMENTS (
Use these instructions for AC and DC measurements).
CAUTION
Never try to measure voltages greater than 750V AC or 1000V DC.
1. Select AC or DC voltage and range. lf range is unknown, start with the highest range. Set function selector to
V=
for DC
measurements or to
V ~
for AC measurements.
2. Plug red test lead to VOLT plug, black test lead to COM plug.
3. Connect black test lead to common of circuit, red lead to point being measured at this circuit.
4. Value at display is actual level being measured, + assumed, - (negative) shown. In AUTO mode only: decimal point is
correctly located for best resolution.
