1. SAFETY INSTRUCTIONS
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 electrical ratings. Failure to do so will invalidate the warranty.

DO NOT use leads if damaged or if the wires are bared in any way.
1.2 GENERAL SAFETY INSTRUCTIONS

Familiarise yourself with the application and limitations of the multimeter as well as the potential hazards.
IF IN ANY DOUBT CONSULT A QUALIFIED ELECTRICIAN.

When the meter is connected to a circuit, do not touch unused meter terminals.

When the magnitude of the value to be measured is unknown, set the range selector to the highest value available.

Before commencing testing, follow instructions below and select the correct input sockets, function and range on the multimeter.

Before rotating the rotary switch to change functions, disconnect the test leads from the circuit under test.

Take care when working with voltages above 60V DC or 30V AC rms. Keep fingers behind the probe barriers whilst measuring.

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.

DO NOT use the multimeter in a potentually explosive atmosphere.

Ensure that the rear cover is in place and fastened before using the multimeter.

Before attempting to insert transistors for testing, ensure that test leads have been disconnected.

Components should not be connected to the transistor socket or capacitor socket when taking voltage measurements with the test leads.

If any abnormal readings are observed, the multimeter must be checked out by an authorised technician.

When not in use, store the multimeter carefully in a safe, dry, childproof location out of direct sunlight. Storage temperature range -10°C to 50°C.
