FOR YOUR SAFETY
1) Use extreme caution when checking electrical circuits.
2)
WARNING Do not stand in wet or damp work areas
!
when working with electricity. Wear rubber soled boots or
shoes.
3)
WARNING Do not apply more voltage or current than
!
the set range of the multitester will allow.
4)
WARNING Do not touch the metal probes of the test
!
leads when making a measurement.
5)
!
WARNING Replace worn test leads. Do not use test
leads with broken or tattered insulation.
6) Discharge a capacitor before measuring it.
7) Remove the test leads from the circuit being measured as
soon as the test is completed. Never reset the
function/range switch to another range while the leads are
still in contact with a circuit.
8) Do not measure voltage when the function/range switch is
set on the resistance (ohms) or the current (mA) settings.
Do not measure current when the tester is set on the
resistance range. Do not measure AC voltage when the
tester is set on DC voltage or DCmA. Setting the tester on
the incorrect function may burn out some of the internal
circuitry and may pose a safety hazard.
OPERATING SUGGESTIONS
1) Set the function/range switch to the proper position before
making a measurement. When the voltage or current is
not known, it MUST be determined that the capacity of the
selected range will handle the amount of voltage or cur-
rent in the circuit (see #3 under "For Your Safety").
2) Avoid placing the tester in areas where vibration, dust or
dirt are present. Do not store the tester in excessively hot,
humid or damp places. This tester is a sensitive measur-
ing device and should be treated with the same regard as
other electrical and electronic devices.
3) When the tester is not in use, switch it OFF to keep the
batteries from discharging.
4) Do not transport the tester using the test leads as a carry-
– 3 –
ing strap.
5) Do not immerse the tester in water or solvents. To clean
the housing use a damp cloth with a minimal amount of
mild soap.
NOTE: With any measurement made by this tester, there will
be some fluctuation of the digital display. This is due to the
testers' sampling method. This unit samples at a rate of two
times per second, thus the fluctuation of the readout.
DC VOLTAGE MEASUREMENT
1) Set the function/range switch to the DC voltage range.
2) If the polarity of the circuit to be tested is known, touch the
black test lead to the neutral side. If the polarity is
unknown, touch the test leads to opposite sides of the cir-
cuit. If the test leads are reversed, the "(-)" indicator will
appear on the display. Reverse the test leads for proper
polarity and read the value indicated on the display.
Common DC Voltage Measurements
Automotive Batteries
Set function/range switch to the 20 DCV setting. First check
the quality of the battery terminal connector by touching the
red (+) test lead to the connector while touching the black (-)
test lead to any bare metal framework of the vehicle. The
tester should read 12 volts or higher with all of the vehicle
accessories turned off. If the display fluctuates rapidly, this
could indicate a bad terminal connection. Remove the termi-
nal connectors and clean both terminals and connectors thor-
oughly. For improved conductivity and corrosIon resistance,
