1.1 PERSONAL PRECAUTIONS
√When using this multimeter, please observe all normal safety rules
concerning:
Protection against the dangers of electrical current.
Protection of the meter against misuse.
√Full compliance with safety standards can only be guaranteed if
used with the test leads supplied. If necessary, they must be
replaced with genuine The test leads supplied with the same
electronic ratings.
Failure to do so will invalidate the warranty.
× DO NOT use leads if damaged or if the wire is bared in any way.
×DO NOT use the meter if it has been damaged.
1.2 GENERAL SAFETY INSTRUCTIONS
WARNING! USE EXTREME CAUTION when working with high
voltages.
√Familiarise yourself with the application and limitations of the
multimeter as well as the potential hazards.
IF IN ANY DOUBT CONSULT A QUALIFIED ELECTRICIAN.
1. SAFETY INSTRUCTIONS
IMPORTANT: PLEASE READ THESE INSTRUCTIONS
CAREFULLY. NOTE THE SAFE OPERATIONAL
REQUIREMENTS, WARNINGS & CAUTIONS. USE THE
PRODUCT CORRECTLY AND WITH CARE FOR THE
PURPOSE FOR WHICH IT IS INTENDED. FAILURE TO DO
SO MAY CAUSE DAMAGE AND/OR PERSONAL INJURY
AND WILL INVALIDATE THE WARRANTY. PLEASE KEEP
THESE INSTRUCTIONS SAFE FOR FUTURE USE.

√
Before commencing testing, follow instructions below and select
the correct input sockets, function and range on the multimeter.
√
When the meter is connected to a circuit, do not touch any unused
meter terminals.
√
When the magnitude of the value to be measured is unknown
beforehand, set the range selector to the highest value available.
√
Before rotating the range selector to change functions, disconnect
test probes from the circuit under test.
WARNING! Never perform resistance, transistor, diode or
continuity measurements on live circuits.
√
Always take care when working with voltages above 35V DC or 25V
AC rms. These voltages are considered a shock hazard.
√
Always keep fingers behind the probe barriers whilst measuring
and DO NOT use when hands are wet.
×
DO NOT touch the test leads, tips or the circuit being tested.
√
Choose the proper range and function for the required
measurement. Do not try voltage or current measurements that
may exceed the ratings marked on the Function/Range switch.
√
When testing for the presence of a voltage or current, make sure
the meter is functioning correctly. Take a reading of a known voltage
or current before accepting a zero reading.
×
DO NOT test voltages above 1000V DC or 750 AC rms the circuitry
of the multimeter will be destroyed.
WARNING! NEVER connect the multimeter to a voltage source /
live circuit when the rotary switch is set to any other function apart
from Voltage testing..
WARNING! Voltage checks on electrical outlets can be difficult and
misleading because of the uncertainty of connection to the
recessed electrical contacts. Other means should be used to
ensure that the terminals are not “live”.
√
Avoid damaging the meter when testing voltage. Disconnect the
test leads from the test points before changing functions.
×
DO NOT attempt a voltage measurement with the test leads in the
20A or the mA terminal.
√
ALWAYS discharge filter capacitors in power supplies and

3
disconnect the power when making resistance or diode tests.
× DO NOT use the multimeter in a potentially explosive atmosphere
or where flammable material is present.
√ ONLY operate the multimeter when the back cover is in place and
fastened securely.
√ If any abnormal readings are observed, the multimeter must be
checked out by an authorised technician.
√ ALWAYS turn off the multimeter and disconnect the test leads,
before opening the back cover to replace the fuse or battery.
√ When not in use, store the multimeter carefully in a safe, dry,
childproof location out of direct sunlight. If storing for a long period
of time, remove the battery. Storage temperature range: -15°C to
50°C.
Note: The warnings, cautions and instructions referred to in this manual
cannot cover all possible conditions and situations that may occur.
It must be understood that common sense and caution are factors
which cannot be built into this product, but must be applied by the
operator.
WARNING! Engines produce carbon monoxide which is odourless
and causes slower reaction time which could lead to serious injury.
An engine which is operating should be in a well ventilated area, or
the vehicle's exhaust should be connected to an adequate fume
removal system.
√When working on a vehicle which is being tested or repaired ensure
that the handbrake is on and the front wheels are chocked to avoid
the vehicle moving and causing injury.
√ Wear suitable eye protection when testing or repairing a vehicle.
√ When measuring current, connect the meter in series with the load.
√ 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 800mA or
20A for 30 seconds.
√ To maintain the accuracy of the meter, replace the discharged
battery immediately when the symbol ‘ ' appears on the meter
display.
√ Avoid measurement errors from outside interference. Keep the
meter away from spark plug and coil wires.
√ Exceeding the electrical limits of this meter is dangerous and
will expose you to serious or possibly fatal injury. Carefully
read and understand the specification limits of this meter
together with the warnings and cautions in this safety section.

5.12 ms-PULSE (Pulse Width) & ms- PERIOD (Period)
5.12.1 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 injector 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.
This exercise shows how to measure Pulse Width (ms) on Port
Fuel injectors.
5.12.2 Select the “ms-PULSE” function with the rotary switch.
5.12.3 Press the Trigger± button, the negative (-) trigger slope is
displayed on the display.
NOTE: The applied time for most fuel injectors is displayed on the
negative (-) slope.
5.12.4 Insert the black lead into the COM terminal.
5.12.5 Insert the red lead into the VΩHz terminal.
5.12.6 Connect jumper wires between the fuel injector and the harness
connector.
5.12.7 Touch the Black test
probe to a good ground at
the fuel injector or the
negative (-) vehicle battery
post.
Fig8

14
5.12.8 Touch the Red test probe to the fuel injector solenoid driver
input on the jumper cable.
5.12.9 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.
5.13 RPM and ×10RPM
5.13.1 Using the rotary switch, select either the RPM range or the
×10RPM range (1,000 to 12,000 RPM) and multiply the displayed
reading by ten to get actual RPM.
5.13.2 Press STROKE / DIS button to select through RPM for
4-stroke, RPM for 2-stroke and DIS ignitions.
5.13.3 Connect the inductive pickup leads to the meter.
5.13.4 Insert the black lead into the COM terminal.
5.13.5 Insert the red lead into the VΩHz terminal.
5.13.6 Open the inductive pickup and place it onto a spark plug
wire. If no reading is received, unhook the clamp, turn it over
and connect again.
Notes:
5.13.7 Position
the inductive
pick-up as far
away from the
distributor and
the exhaust
manifold as
possible.
5.13.8 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.

5-14 Non Contact AC Voltage (NCV) detection
5.14.1 Power on the meter, on any range, press and hold the
“NCV” key, the meter enters Non Contact AC Voltage (NCV)
detection, the NCV green LED light will light up.
5.14.2 Hold the Meter so that the mater’s top is vertically and
horizontally centered and contacting the conductor, when the live
voltage ≥ 90V AC rms, the NCV red LED light and green LED light
will light up alternately together with sound.
NOTE:
1. Even without LED indication, the voltage may still exist. Do not
rely on non-contact voltage detector to determine the presence of
voltage wire. Detection operation may be subject to socket design,
insulation thickness and different type and other factors.
2. When the meter input terminals presence voltage, due to the
influence of presence voltage, voltage sensing indicator may also
be bright.
3. Keep the meter away from electrical noise sources during the
tests, i.e., florescent lights, dimmable lights, motors, etc.. These
sources can trigger Non-Contact AC Voltage detection function
and invalidate the test.
