 Safety precautions
Safety
DANGER
 Engines produce carbon monoxide which
is odorless, causes slower reaction time,
and can lead to serious injury. When the
engine is operating, keep service areas
WELL VENTILATED or attach the vehicle
exhaust system to the shop exhaust
removal system.
 Set the parking brake and block the
wheels before testing or repairing the
vehicle. It is especially important to block
the wheels on front-wheel drive vehicles;
the parking brake does not hold the drive
wheels.
 Wear an eye shield when testing or
repairing vehicles.
Exceeding the limits of this meter is
dangerous. This will expose you to serious
or possibly fatal injury. Carefully read and
understand the cautions and the
specification limits of this meter.
 Voltage between any terminal and ground
must not exceed 600V DC or 600V AC.
 Use caution when measuring voltage above 25V DC or 25V AC.
 Circuit tested must be protected by a 20A fuse or circuit breaker.
 Do not use the meter if it has been damaged.
 Do not use the test leads if the insulation is damaged or if metal
is exposed.

Danger
 Avoid electrical shock: do not touch the test
leads, tips or the circuit being tested.
 Do not try a voltage measurement with the
test leads in the 20A or the mA terminal.
 When testing for the presence of voltage or current, make sure
the meter is functioning correctly. Take a reading of a known
voltage or current before accepting a zero reading.
 Choose the proper range and function for the measurement. Do
not try voltage or current measurements that may exceed the
ratings marked on the Function/Range switch or terminal.
 When measuring current, connect the meter in series with the
load.
 Never connect more than one set of test leads to the meter.

Disconnect the live test lead before disconnecting the common
test lead.
 The mA and the 20A terminals are protected by fuses. To avoid
possible injury or damage, use only in circuits limited to 400mA
or 20A for 30 seconds.

IMPORTANT

To maintain accuracy of the meter, replace the discharged
battery immediately when the symbol “BAT” appears on the
meter display.
 Avoid measuring error from outside interference. Keep the
meter away from spark plug or coil wires.
 Avoid damaging the meter when testing voltage. Disconnect
the test leads from the test points before changing functions.

Meter Functions – Resistance (Ω)
IMPORTANT: If you are testing
an application that has capacitors
in the circuit, be sure to turn the
power OFF on the test circuit and
discharge all capacitors. Accurate
measurement is not possible if
external or residual voltage is
present.
Select the Resistance “ Ω”

Note:
A “good” diode will read low in one
`direction and high in the other direction
when the probes are reversed (or vice
versa).

Meter Functions – Capacitance ( CAP )
IMPORTANT: Turn the power OFF to
the test circuit
select the Capacitance “ CAP “
function with the rotary switch and
mode button
Insert:
Black lead in COM terminal.
Red lead in V-Ω-RPM terminal
CAUTION: When checking in-circuit
capacitance, be sure
that the circuit has all power
removed and all capacitors are
fully discharged.
Touch the test lead probes across the
capacitance circuit to be tested.
Read the measured value from the
LCD display.
Note:
1. The bar graph is disabled in capacitance measurement mode.
However, since the measurement time of 4mF and 40mF
modes is quite long (3.75s and 7.5s respectively,
to be precise), the bar graph is instead used to
display the time required to accomplish the measurement.
2. In order to obtain an accurate reading,
a capacitor must be discharged before measurement begins. The meter has a
built-in discharge mode to automatically discharges the capacitor. In
discharge mode, the LCD displays “DIS.C”
3. Discharging through the chip is quite slow. We recommend the user to
discharge the capacitor with some other apparatus.
Meter Functions –Audible Continuity ( )
IMPORTANT: Turn the power
OFF on the test circuit
Select the Audible Continuity

Meter Functions- ms-PULSE (Pulse Width) &
ms- PERIOD (Period)
Pulse Width is the length of time an actuator is energized. For
example, fuel injectors are activated by an electronic pulse from
the Engine Control Module (ECM).
This pulse generates a magnetic field that pulls the injectors nozzle
valve open.
The pulse ends and the injector nozzle is closed.
This open to close time is the Pulse Width and is measured in
milliseconds( ms).
The most common automotive application for measuring pulse
width is on fuel injectors.
You can also measure the pulse width of the fuel mixture control
solenoid and the idle air control motor.
Measuring Pulse Width on Port Fuel injectors is described on the
following page.

injector and the harness
connector.

ground at the fuel injector or the
negative (-) vehicle battery post.
Red test probe to the fuel
injector solenoid driver input on
the jumper cable.
Start the engine. A pulse width in
milliseconds should be read.
Note: Initially, the unit will read
“OL”, then readings will descend
and stabilize to the actual pulse
width. If “OL” remains,
re-check your connections.

turn it over and connect again.
Note:
 Position the inductive pick-up as far away from the distributor and the
exhaust manifold as possible.
 Position the inductive pick-up to within six inches of the spark plug or move
it to another plug wire if no reading or an erratic reading is received.
