DC/AC VOLTAGE MEASUREMENTS
WARNING:
Maximum input for DC V is 600, and for AC V is
600. Do not attempt to take any voltage measurement that
exceeds the limits. Exceeding the limits could cause electrical
shock and damage to the
meter.

1.
Set the rotary switch at V and move the sliding switch to DC.
2.
Insert the test leads into the input jack.
3.
Connect the test prods of the test leads in PARALLEL to the
circuit to be measured.
4.
Read the measured value from the LCD display.

STARTER DRAW TEST
STARTER SETUP
1.
Check with manufacture’s proper procedure to disable ignition if
needed. Improper methods could cause damage to vehicles that
are computer controlled.
2.
Determine the manufactures Starter Draw specifications. If not
available use the following chart as a guide.
3.
Select DC 200 Amp and zero the DM-46 by pressing the yellow
button.
4.
Press the MAX/MIN button twice and make sure the display reads
HOLD MAX.
5.
Clamp the DM-46 around the positive conductor leading to the
starter (See illustration above). Make sure the small arrow inside
the clamp is pointing in the direction of the current towards the
starter. Also make sure the DM-46 is clear of any moving belts,
fan blades or anything that might damage the meter.
6.
Crank the engine for 3 to 5 seconds.
7.
Read the DM-46 and compare with manufactures specifications.
8.
High Amp reading indicates a faulty starter or engine timing
that would put an extra load upon the starter. Possible starter
problems are shorted windings, bent armature, broken housing or
bad bearings.
