1.1. PERSONAL PRECAUTIONS

! When using this meter, please observe all normal safety rules concerning:

Protection against the dangers of electric 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.

1.2. GENERAL SAFETY INSTRUCTIONS

! Familiarise yourself with the application and limitations of the meter as well as the potential hazards. IF IN ANY DOUBT CONSULT A QUALIFIED ELECTRICIAN.
! When the meter is linked to a measurement circuit, do not touch unused meter terminals.
! When the scale of the value to be measured is unknown set the selector to the highest range available.
! Before rotating the range selector to change functions, disconnect test leads from the circuit under test.
# WARNING! Never perform resistance measurements on live circuits.
! Always be careful when working with voltages above 60Vdc or 30Vac rms. Keep your fingers behind the probe barriers while measuring.
! When not in use, store the meter carefully in a safe, dry, childproof location. Storage temperature range -10

O

C to 50OC.

! Never apply voltage or current to the meter that exceeds the specified maximum.
