HOW
TO
MEASURE
AC
VOLTAGES
[-] Plug the black test lead into the jack marked -COM. Plug
the red test lead into the jack marked VOA.
(] Set the upper slide switch to AC.
(] Rotate the selector switch to the ACV range which will pro-
vide a reading at the right hand side of the scale.
[| Clip the black test lead to one terminal of the voltage to be
measured and the red test lead to the other.
NOTE:
For
high
voltages,
follow
the
same
precautions
as
noted
in
the
section
on
'HOW
TO
MEASURE
DC
VOLTAGES".
Use the RED
AC
scales for voltage
readings
of 2, 4 and 8
volts. The BLACK
scales are used for voltage readings of 16
through 4000 volts.
For readings of 0-2 volts, set the selector switch to 4 and the
scale multiplier switch to aie Read on the RED
0-2 AC scale,
— each division being equal to .1 volt.
For readings of 0-4 volts, set the selector switch to 4 and the
scale multiplier switch to VA. Read on the RED
0-4 AC scale,
each division being equal to .2 of a volt.
For readings of 0-8 volts, set the selector switch to 16 and the
seale multiplier switch to ee Read on the RED
0-8 AC scale.,
—each
division being equal to .2 of a volt.
For readings of 0-16 volts, set the selector switch to 16 and the
scale multiplier switch to VA. Read on the BLACK
0-16 AC
scale, —
each division being equal to .4 of a volt.
For readings of 0-40 volts, set the selector switch to 80 and the
scale multiplier switch to ™. Read on the BLACK
0-400 AC
scale, —- each division being equal to 1 volt.
For readings of 0-80 volts, set the selector switch to 80 and the
scale multiplier switch to VA. Read on the BLACK
0-80 AC
scale, — each division being equal to 2 volts.
For readings of 0-200 volts, set the selector switch to 400 and
the scale multiplier switch to ". Read on the BLACK
0-200
AC scale, — each division being equal to 5 volts.
For readings of 0-400 volts, set the selector switch to 400 and
the scale multiplier switch to =. Read on the BLACK 0-400
AC scale, — each division being equal to 10 volts.
4000
For readings of 0-800 volts, set the selector switch to 1600 and
scale, — each division being equal to 20 volts.
4000
For readings of 0-1600 volts, set the selector switch to 1600 and
the scale multiplier switch to VA. Read on the BLACK 0-16 AC
scale, — each division being equal to 40 volts.
4000
For readings of 0-2000 volts, set the selector switch to 1600 and
4KV
jack marked AC. Read on the BLACK
0-200 AC scale, —
each
division being equal to 50 volts.
4000
For readings of 0-4000 volts, set the selector switch to 1600 and
the scale multiplier switch to VA. Place the red test lead into
4KV
the jack marked AC. Read on the BLACK
0-400 AC scale, —
each division being equal to 100 volts.
