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.

show the status of the insulation voltage for the item tested. Turning the function switch to off or pressing the EXIT button will exit fro m the testing procedure during the process.

POWER TOOLS AND SMAL L AP PLI ANCES

This test would also apply to other similar equipment that has a line cord. For double insulated power tools, the megohmmeter lead shown connected to the housing would be connected to some metal part lf the tool(e.g. chuck, blade). Note: The switch of the device must be in the “ON” position and the main power should be disconnected.

MOTORS

AC-Disconnect the motor from the line by disconnecting the wires at the motor terminals or by opening the main switch. If the main switch is used and the motor also has a starter then the starter must be held, by some means, in the “ON” position. In the latter case, the measured resistance will include the resistance of the motor, wire and all other components between the motor and the main switch. If a weakness is indicated, the motor and other components should be checked individually. If the motor is disconnected at the motor terminals, connect one megohmmeter lead to the grounded motor housing and the other lead to one of the motor leads. DC - Disconnect the m otor from the line. To test the brush rigging, field coils and armature

connect one megohmmeter lead to the grounded m otor housing and the other lead to the brush on the commutator. If the resistance measurement indicates a weakness, raise the brushes off the commutator and separately test the armature, field coils and brush rigging by connecting one megohmmeter lead to each of them individually, leaving the other connected to the grounded motor housing. The above also applies to DC Generators.

CABLES

Disconnect the cable from the line. Also disconnect opposite end to avoid errors due to leakage from other equipment. Check each conductor to ground and /or lead sheath by connecting one megohmmeter lead to a ground and /or lead sheather and the other megohmmeter lead to each of the conductors in turn. Check insulation resistance between conductors by connecting megohmmeter leads to conductors in pairs.

AUTORANGING/MANUAL RANGE SELECTION

3. HANDLE THE METER GENTLY AND CAREFULLY. Dropping it can damage the electronic parts or the case.

4. KEEP THE METER CLEAN. Wipe the case occasionally with a damp cloth. DO NOT use chemicals, cleaning solvents, or detergents.

5. USE ONLY NEW BATTERIES OF THE RECOMMENDED SIZE AND TYPE. Remove old batteries so they do not leak and damage the unit.

6. IF THE METER IS TO BE STORED FOR A LONG PERIOD OF TIME, the batteries should be removed to prevent damage to the unit.

BATTERY INSTALLATION

WARNING: To avoid electric shock, disconnect the test leads from

any source of voltage before removing the battery cover.

1. Turn power off and disconnect the test leads from the meter.

2. Open the rear battery cover by removing 4 screws using a cross head screwdriver.

3. Insert the batteries into battery holder, observing the correct polarity.

4. Put the battery cover back in place. Secure with the screws.

WARNING: To avoid electric shock, do not operate the meter until the battery cover is in place and fastened securely.

NOTE: If your meter does not work properly, check the fuses and

batteries to make sure that they are still good and that they are properly inserted.

REPLACING THE FUSES

WARNING: To avoid electric shock, disconnect the test leads from

any source of voltage before removing the meter cover.

1. Disconnect the test leads from the meter.

2. Remove the protective rubber holster.

3. Remove the battery cover (4 screws) and the batteries.

4. Remove the six screws securing the rear cover.

5. Gently remove the old fuse and install the new fuse into the holder.

6. Always use a fuse of the proper size and value (0.5A/1000V fast blow for the 400mA range, 10A/1000V fast blow for the 20A range.

7. Replace and secure the rear cover, battery and battery cover.

WARNING: To avoid electric shock, do not operate your meter until the fuse cover is in place and fastened securely.
