Simpson 260 - Measuring Resistances

OPERATING INSTRUCTIONS
Set the range switch at the desired resist-
ance range position and the function switch
at either -D.C. or *D.C.
Connect the black test lead in the COMMON-
jack and the red test lead in the + jack.
Clip the contact ends of the test leads to-
gether to produce zero resistance.
Observe the meter indication. It should
read on zero at the right hand end of the
OHMS arc at the top of the scale.
If the pointer does not read zero, set f on
the line with the ZERO OHMS control. If this
cannot be done, one or more batteries need
to be replaced.
When the zero has been adjusted, unclip the
shorted test leads; the ohmmeter circuit is
now ready to measure resistance,
MEASURING RESISTANCES
1.

3.
To measure resistance, proceed as follows:
Set the range switch in one of the resistance
range positions.
Use R x 1 for resistance readings from
O to 200 ohms.
Use R x 100 for resistance readings from
200 to 20,000 ohms.
Use R x 10,000 for resistance readings
above 20,000 ohms.
Set the function switch at either -D.C. or
* D.C.
Connect the black test lead in the COMMON-
jack and the red test lead in the + jack.
