1. SAFETY
1.1. PERSONAL PRECAUTIONS
9 When using the analyser, please observe all normal safety rules concerning:
Protection of the analyser against misuse.
1.2. GENERAL SAFETY
Protection against the dangers of electric current.
9 Full compliance with safety standards can only be guaranteed if used with the test leads supplied. If necessary, these must be replaced
with genuine Sealey leads with the same electronic ratings. Failure to do so will invalidate the warranty.
88 88 DO NOT use leads if damaged or if the wire is bared in any way.
9 Familiarise yourself with the application and limitations of the analyser as well as the potential hazards. IF IN ANY DOUBT CONSULT A
QUALIFIED ELECTRICIAN.
9 When the analyser is linked to a measurement circuit, DO NOT touch unused analyser terminals.
9 When the scale of the value to be measured is unknown set the selector to the highest range available.
9 Before rotating the function dial to change functions, disconnect test leads from the circuit under test.
WARNING! Never perform resistance measurements on live circuits. Only measure on disconnected circuits.
9 Use caution when working with voltages above 60V DC or 30V AC. Keep fingers behind the probe barriers whilst measuring.
89 88 When not in use, store the analyser carefully in a safe, dry, childproof location. Storage temperature range -10°C to 50°C.
88 88 Never apply voltage or current to the analyser that exceeds the specified maximum.
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.
8 88 WARNING! DO NOT make current measurements on the 10A scale for longer than 15 seconds in every 15 minutes.
Exceeding 15 seconds may cause damage to the analyser and test leads.
