1. SAFETY
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
sealey leads 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.
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 600V Ac or Dc - 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 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 400mA or 20A for 30 seconds.
to maintain the accuracy of the meter, replace the discharged battery immediately when the symbol '
BAT' 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.
DO NOT EXCEED ThE LIMITS ShOWN IN ThE TABLE BELOW.

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. KEEP ThESE INSTRUCTIONS SAFE FOR FUTURE USE.
T
hank you for purchasing a Sealey product. Manufactured to a high standard, this product will, if used according to these instructions, and properly
maintained, give you years of trouble free performance.
t
he 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.
