GENERAL SAFETY PRECAUTIONS.

 Wear safety eye protection that meets ANSI standards.
 Operate the vehicle to be tested in a well ventilated area. Exhaust gases are

poisonous. If necessary connect the vehicle exhaust to a fume extraction system.
 Place chocks in front of the drive wheels and never leave the vehicle unattended
whilst testing is in progress.
 Be extra cautious when working in close proximity to the ignition coil, distributor
cap, ignition wires and spark plugs. These components create hazardous voltages
when the engine is running.
 Ensure that the handbrake is on and the gearbox is in neutral or ‘Park’ for
automatic transmissions.

 Keepreextinguishersnearbythataresuitableforpetrol/chemical/electricalres.

 Keep the analyser clean and in good condition.
 Remain vigilant when using the code reader on, or near, machinery where there are

rotational parts such as belts, pulleys and fans.

 Removeillttingclothing.Removeties,watches,rings,andotherloosejewellery,

and contain and/or tie back long hair.

 Maintaincorrectbalanceandfooting.Ensuretheoorisnotslipperyandwear

non-slip shoes.

 Keep product surfaces clean and dry.
 The user shall ensure that test probes are correctly selected in order to prevent

danger. Probes shall be selected to ensure that adequate barriers guard against
inadvertent hand contact with live conductors under test and that probes have
minimal exposed probe tips. Where there is a risk of the probe tip short circuiting
with other live conductors under test, it is recommended that the exposed tip length
shall not exceed 4mm.
 DO NOT attempt to connect or disconnect any test equipment whilst the ignition
is on or the engine is running.
 DO NOT use the analyser if damage is suspected. If suspected damage occurs

 withthedevice,haveitinspectedbyqualiedservicepersonnelbeforeusingit

again.
 DO NOT get the analyser wet or use in damp or wet locations or areas where
there is condensation.

 DO NOT use the analyser for any purpose other than for which it is designed.
 DO NOT allow untrained persons to use analyser.
 DO NOTusetheanalyserwhenyouaretiredorundertheinuenceofalcohol,

drugs or intoxicating medication.

 DO NOT operate in a potentially explosive environment/atmosphere.
 WARNING: The warnings, cautions and instructions discussed in this instruction

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.

Thank you for purchasing a Sealey product. Manufactured to a high standard, this product will give you years of
trouble free performance, if these instructions are carefully followed and the product is correctly maintained.

must refer to an explanation in the Operating
Instructions to avoid personal injury or damage to
the meter.

This WARNING symbol indicates a potentially
hazardous situation, which if not avoided, could
result in death or serious injury.

This CAUTION symbol indicates a potentially
hazardous situation, which if not avoided, may
result in damage to the product.

This symbol advises the user that the terminal(s)
so marked must not be connected to a circuit point
at which the voltage with respect to earth ground
exceeds (in this case) 1000 VAC or VDC.

This symbol adjacent to one or more terminals
identifies them as being associated with ranges
that may, in normal use, be subjected to
particularly hazardous voltages. For maximum
safety, the meter and its test leads should not be

Frequency, Resistance,
Diode Test, Continuity

This meter has been designed for safe use, but must be operated with
caution. The rules listed below must be carefully followed for safe
operation.

1. NEVER apply voltage or current to the meter that exceeds the

specified maximum:

Input Protection Limits

Function Maximum Input
V DC or V AC 1000VDC/AC rms
mA AC/DC 500mA 1000V fast acting fuse

A AC/DC

Capacitance, Duty Cycle,

Temperature 1000VDC/AC rms
Surge Protection: 8kV peak per IEC 61010

2. USE EXTREME CAUTION when working with high voltages.

3. DO NOT meas ure voltage if t he voltage on the "COM" input jack
exceeds 1000V above earth ground.

4. NEVER connect the meter leads across a voltage source while
the function switch is in the current, resistance, or diode mode.
Doing so can damage the meter.

5. ALWAYS discharge filter capacitors in power supplies and
disconnect the power when making resistance or diode tests.

6. ALWAYS turn of f the power and disconnec t t he test leads before
opening the covers to replace the fuse or batteries.

for 30 seconds max every 15

1000VDC/AC rms

7. NEVER operate the meter unless the back cover and the battery
and fuse covers are in place and fastened securely.

If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be
impaired.

Operating Instructions

WARNING: Risk of electrocution. High-voltage circuits, both AC and
DC, are very dangerous and should be measured with great care.

1. ALWAYS turn the function switch to the OFF position when the
meter is not in use.

2. If “OL” appears in the display during a measurement, the value
exceeds the range you have selected. Change to a higher range.

DC VOLTAGE MEASUREMENTS

CAUTION: Do not measure DC voltages if a motor on the circuit

is being switched ON or OFF. Large voltage surges may occur
that can damage the meter.

1. Set the function switch to the green VDC
position.

2. Insert the black test lead banana plug into the
negative COM jack.
Insert the red test lead banana plug into the
positive V jack.

3. Touch the black test probe tip to the negative
side of the circuit.
Touch the red test probe tip to the positive
side of the circuit.

4. Read the voltage in the display.

AC VOLTAGE (FREQUENCY, DUTY CYCLE) MEASUREMENTS

WARNING: Risk of Electrocution. The probe tips may not be long

enough to contact the live parts inside some 240V outlets for
appliances because the contacts are recessed deep in the outlets.
As a result, the reading may show 0 volts when the outlet actually
has voltage on it. Make sure the probe tips are touching the metal
contacts inside the outlet before assuming that no voltage is
present.

CAUTION: Do not measure AC voltages if a motor on the circuit
is being switched ON or OFF. Large voltage surges may occur
that can damage the meter.

1. Set the function switch to the green
VAC/Hz/% position.

2. Insert the black test lead banana plug
into the negative COM jack.
Insert red test lead banana plug into the
positive V jack.

3. Touch the black test probe tip to the
neutral side of the circuit.
Touch the red test probe tip to the “hot”
side of the circuit.

4. Read the voltage in the main display and
the frequency in the right auxiliary
display

5. Press and hold the MODE button 2 second to indicate “Hz”.

6. Read the frequency in the main display.

7. Press the MODE button to indicate “%”.

8. Read the % of duty cycle in the main display.

9. Press EXIT for 2 seconds into the function of AC+DC. Test DC
and AC True Rms.
