Execute and
verify steps 2
through 8 of Table
4-2,
using the procedure
described in step
2.
4-29. Continuity Test
4-00. Use the following procedure
to verify
proper operation of the continuity function:
1.
Select the
f!
function
and
2
kH
range.
2.
Connect
the test leads to the
COMMON
and
V/fl terminals.
3.
Depress
the
AC/
DC
switch to activate the audible
tone.
4.
Momentarily short the
test
leads together
and
observe that the tone sounds.
WARNING
THE LOCAL
LINE
VOLTAGE
IS
USED
IN
THE FOLLOWING
STEP. BE
CAREFUL
NOT TO
TOUCH
THE PROBE
TIPS
WITH FINGERS OR ALLOW
THE
120V
AC RECEPTACLE TO BECOME
SHORTED.
5.
At
a
convienient 120
VAC
receptacle, insert test leads as
if
to
measure
line
voltage.
A
series
of beeps
at a rate of
approximately
5 to
10
per
second
indicates
proper operation of the pulse stretcher
circuit.
4-31.

Use
the following
procedure
to
check the accuracy
and
overall operation of the dc
voltage ranges.
