For maximum safety, avoid touching the Instrument or the test leads while the
power is on in the circuit being measured.

Set the function switch to AC.
Set the range switch to one of the six voltage range positions marked 2.5V,
10V, 25V, 100V, 250V or 500V. When in doubt about the approximate voltage
in the circuit being measured, always use a sufficiently high voltage range as
a protection to the Instrument. If the voltage is within a lower range, the
switch then may be set to a lower range to obtain a more accurate reading.
Plug the black test lead into the –COMMON jack and the red test lead into the
+jack.
Be sure the power is off in the circuit being measured and all the capacitors
have been discharged.
Connect the test lead across the voltage source with the black lead on the
ground side.
Turn on the power in the circuit being measured and read the voltage on the
red scale marked AC.
For the 0-2.5V range, read the value directly on the red scale marked 2.5V
AC. For the 10V, 25V, 50V, 100V, 250V and 500V ranges, read the red scale
marked AC and use the black figures immediately above the scale. For the
10V and 250V ranges, read directly using the 0-10 and 0-250 figures respec-
tively. For the 500V range, read directly on the 0-50 figures and multiply the
reading by 10. For the 100V range, read the 0-10 figures directly and multiply
the reading by 10. For the 25V range, use the 0-250 figures and divide by 10.
Turn power off, disconnect the test leads and return the range switch to the
OFF/TRANSIT position.
Set the function switch to AC.
Set the range switch to 1000V (dual position with 500V).
Plug the black test lead into the –COMMON jack and the red test lead into the
1000V jack.
