WARNING: TO AVOID THE RISK OF
ELECTRICAL SHOCK AND INSTRUMENT
DAMAGE, INPUT VOLTAGES MUST NOT
EXCEED 600V DC OR AC RMS. DO NOT
ATTEMPT TO TAKE ANY UNKNOWN
VOLTAGE MEASUREMENT THAT MAY BE IN
EXCESS OF 600V DC OR AC RMS.
NOTE:
When taking voltage measurements, this
Meter must be connected in PARALLEL
with the circuit, or circuit element under
test.
• To measure voltage:
• Select the Voltage (V or
rotary switch.
• Press the DC/AC button to select AC or
DC.
Insert:
• Black lead in COM jack.
• Red lead in RPM, VΩ jack.
-Touch the Black probe to the negative (–)
circuit or to ground.
-Touch the Red probe to the circuit coming
from the power source.

Accuracy:
A measurement range determines the
highest value the Meter can measure.
Most Meter functions have more than one
range.
Being in the right measurement range is
very important when measuring.
Selection of a lower range will move the
decimal point one place and increase the
accuracy of the reading. An
display means the range is too low; select
the next higher range.
Analog Bar Graph:
The bar graph is easier to read when the
data causes the digital display to rapidly
change. It is also useful for trend setting or
directional data.
Resistance Measurements.
Resistance is measured in Ohms (Ω) and
the values can greatly vary from a few
Milliohms (mΩ) for contact resistance to
billions of ohms for insulators. The Meter
can measure down to about 0.1 Ohms and
measure as high as 40 MΩ.
WARNING: TURN OFF POWER AND
DISCHARGE ALL CAPACITORS ON CIRCUIT
TO BE TESTED BEFORE ATTEMPTING
INCIRCUIT RESISTANCE MEASUREMENTS.
ACCURATE MEASUREMENT
POSSIBLE IF EXTERNAL OR RESIDUAL
VOLTAGE IS PRESENT.
NOTE: The resistance in the test leads
can affect accuracy in the 400Ω range.
Short the leads together and subtract the
test lead resistance from the resistance
measurements.
To measure resistance:
• Select the Resistance (Ω) setting with the
