OPERATING INSTRUCTIONS
Set the function switch at +D.C.
Connect the black test lead in the COMMON-
jack and the red lead in the 50 UAMPS jack.
Set the range switch at 50 UAMPS (50 V.).
Open the circuit in which the current is to
be measured, Connect the meter in series
with it, the red lead toward the positive
side, and the black test lead to the negative.
Turn on the power in the circuit which is to
be measured, Observe the meter. Т? the
pointer is deflected to the left, the current
polarity is reversed. Turn off the power and
reverse the leads (the function switch is not
in circuit on this range). Turn on power.
Read the current directly on the black D.C.
arc. Use the 0-50 figures. The current value
is shown in microamperes.
Turn off the circuit power. Remove the test
leads and restore the circuit continuity.
