Simpson 2 Series - Adjust Pointer for Zero

Operating Instructions
ADJUST POINTER FOR ZERO
Before any measurements are made, check to see that the
pointer indicates zero when the meter is in its operating
position. If the pointer is off zero, adjust the screw located
in
the
phenolic
case
below
the
center
of
the
meter
scale,
as
shown
in
Figure
1.
Use
a
small
screwdriver
to
turn
this
screw slowly clockwise or counterclockwise until the
pointer is exactly over the zero mark at the left side of
the scale.
D.C. VOLTAGE MEASUREMENTS,
0-250 MILLIVOLT RANGE ONLY
. Set the function switch at +D.C.
Connect the black test lead in the COMMON - jack and
the red test lead in the SO&AMPS jack.
. Set the range switch at 50 HhAMPS (common position
with 50 V.).
Connect the black test lead to the negative side of the
circuit to be measured, and the red test lead to the
positive side of the circuit.
. Turn on power. If meter deflects to left of zero, turn
off power and reverse the test lead connections. Then
turn on power again.
. Read the voltage on the black arc marked D.C., and use
the figures marked 0— 250; read directly in millivolts.
Turn off power in the circuit which is being measured
before disconnecting meter leads.
