11 FUNCTION DIGITAL AUTOMOTIVE ANALYSER
MODEL NO: TA102
Thank 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.
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.
1. SAFETY
1.1. PERSONAL PRECAUTIONS
9When using the analyser, please observe all normal safety rules concerning:
Protection against the dangers of electric current.
Protection of the analyser against misuse.
9Full 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.
8888 DO NOT use leads if damaged or if the wire is bared in any way.
1.2. GENERAL SAFETY
9Familiarise yourself with the application and limitations of the analyser as well as the potential hazards. IF IN ANY DOUBT CONSULT A
QUALIFIED ELECTRICIAN.
9When the analyser is linked to a measurement circuit, DO NOT touch unused analyser terminals.
9When the scale of the value to be measured is unknown set the selector to the highest range available.
9Before 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.
9Use caution when working with voltages above 60V DC or 30V AC. Keep fingers behind the probe barriers whilst measuring.
8988 When not in use, store the analyser carefully in a safe, dry, childproof location. Storage temperature range -10°C to 50°C.
8888 Never apply voltage or current to the analyser that exceeds the specified maximum.
9The 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.
