5. Read the voltage on the black DC scales.
If the range doubler switch is in the V-A/2 position, be sure
to divide the range switch setting by 2 and read on the
appropriate scale.
6. For voltages between 250 and 1000, set the range switch
to 250 & 1000 and plug the red lead into @ DC 1000V jack.
For voltages between 250 and 500, set the range doubler
switch to V-A/2. (The range is then 500 volts.)
For voltages between 500 and 1000, set the range doubler
switch to V-0-A. (The range is then 1000 volts.)

Making Measurements
Note: The @ DC 1000V jack is for use only with DC Netitral dr
voltages of 250 to 1000V. USE EXTREME CARE WHEN Ground wire ‘Hot” wire
USING THESE HIGH-VOLTAGE RANGES.
Test unit
Hints: When you use the tester to probe for a voltage in a [woo %
high voltage circuit, we recommend that you do not try to oe
position both of the probes at once. Instead, you should
clamp one of the leads to the neutral or ground lead of the
circuit (usually a bare, green or white lead in AC wiring circuit)
using our Insulated Slip-On Alligator Clips (Cat. No. 270-354),
and then probe for voltages with the other probe. This helps
to prevent you from accidentally touching a “hot’’ wire, since
you need only concentrate on one test probe. Never clamp
on to a “hot” wire, (usually red, black or blue in AC wiring
circuit), since if you did so and then touched the other probe
connected to the meter, you could receive an electric shock.
