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
9
When using this meter, please observe all normal safety rules concerning:
Protection against the dangers of electric current.
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 electronic ratings. failure to do so will invalidate the warranty.
8
do not
use leads if damaged or if the wire is bared in any way.
1.2.
general safety instruCtions
9
familiarise yourself with the applications, limitations and hazards of the meter.
if in any doubt consult a qualified electrician.
9
When the meter is linked to a measurement circuit,
do not
touch unused meter 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 range selector to change functions, disconnect test leads from the circuit under test.
Warning!
never perform resistance measurements on live circuits.
9
Always be careful when working with voltages above 60Vdc or 30Vac rms. Keep your fingers behind the probe guards while measuring.
9
When not in use, store the meter carefully in a safe, dry, childproof location. storage temperature range -10°c to 50°c
8
do not
apply voltage or current to the meter 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.
2. Per ieC1010 overvoltage installation Category
2.1.
overvoltage category i
equipment of overvoltage category i is equipment for connection to circuits in which measures are taken to limit the transient
overvoltages to an appropriate low level.
note – examples include protected electronic circuits.
2.2.
overvoltage category ii
Equipment of overvoltage category II is energy-consuming equipment to be supplied from the fixed installation.
note – examples include household, office, and laboratory appliances.
2.3.
overvoltage category iii
Equipment of overvoltage category III is equipment in fixed installations.
note – examples include switches in the fixed installation and some equipment for industrial use with permanent connection to the
fixed installation.
2.4.
overvoltage category iV
equipment of overvoltage category iV is for use at the origin of the installation.
note – examples include electricity meters and primary over-current protection equipment
