Shock Hazard
1. SAFETY
1.1. PERSONAL PRECAUTIONS
9 When using this multimeter, please observe all normal safety rules concerning:
9 Protection against the dangers of electrical current.
9 Protection of the meter against misuse.
9 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 electrical ratings. Failure to do so will invalidate the warranty.
8 DO NOT use leads if damaged or if the wires are bared in any way.
1.2. GENERAL SAFETY INSTRUCTIONS
9 Familiarise yourself with the application and limitations of the multimeter as well as the potential hazards.
9 IF IN ANY DOUBT CONSULT A QUALIFIED ELECTRICIAN.
▲ USE EXTREME CAUTION when working with high voltages.
9 When the meter is connected to a circuit, DO NOT touch unused meter terminals.
9 When the magnitude of the value to be measured is unknown, set the range selector to the highest value available.
9 Before commencing testing, follow instructions below and select the correct input sockets, function and range on the multimeter.
9 Before rotating the rotary switch to change functions, disconnect the test leads from the circuit under test.
9 Take care when working with voltages above 35V DC or 25V AC rms. These voltages are considered a shock hazard. Keep fingers behind
the probe barriers whilst measuring.
8 DO NOT test voltages above 600V - the circuitry of the multimeter may 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! NEVER perform resistance, transistor, diode or continuity measurements on live circuits.
9 ALWAYS discharge lter capacitors in power supplies and disconnect the power when making resistance or diode tests.
WARNING! Voltage checks on electrical outlets can be dicult 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”.
8 DO NOT use the multimeter in a potentially explosive atmosphere.
9 NEVER operate the meter unless the back cover and the battery and fuse doors are in place and fastened securely.
9 If any abnormal readings are observed, the multimeter must be checked out by an authorised technician.
9 When not in use, store the multimeter carefully in a safe, dry, childproof location out of direct sunlight.
9 Storage temperature range -20°C to 60°C.
9 ALWAYS turn o the power and disconnect the test leads before opening the doors to replace the fuse or batteries.
9 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.
WARNING! NEVER apply voltage or current to the meter that exceeds the specified maximum as shown below:
Input Limits
Function Maximum Input
Amps AC 400A
Volts DC, Volts AC 600V DC / AC
Resistance, Diode, Continuity 250V DC / AC
▲ WARNING! USE EXTREME CAUTION when working with high voltages.
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! To avoid electric shock, disconnect the test leads from any source of voltage
before removing the battery cover.
1.3.1. Disconnect the test leads from the meter.
1.3.2. Open the battery cover by loosening the cover screw using a cross-head screwdriver.
1.3.3. Insert the battery into battery holder, observing the correct polarity.
1.3.4. Replace the battery cover. Secure with the screw.
WARNING! To avoid electric shock, DO NOT operate the meter until the battery cover is in place
and fastened securely.
NOTE! If the meter does not work properly, check the battery to make sure that it is still charged and that it
is properly inserted.
