1. safety
1.1. personal precautions
When using this multimeter, please observe all normal safety rules concerning:
9
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
9
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.

general safety instructions

familiarise yourself with the application and limitations of the multimeter as well as the potential hazards.
9
if in AnY douBt consult A QuAlified electriciAn.
Warning! use eXtreme cAution when working with high voltages.
‰
When the meter is connected to a circuit, do not touch unused meter terminals.
9
When the magnitude of the value to be measured is unknown, set the range selector to the highest value available.
9
Before commencing testing, follow instructions below and select the correct input sockets, function and range on the multimeter.
9
Before rotating the rotary switch to change functions, disconnect the test leads from the circuit under test.
9
take care when working with voltages above 35V dc or 25V Ac rms. these voltages are considered a shock hazard.
9
Keep fingers behind the probe barriers whilst measuring.
9
do not test voltages above 600V - the circuitry of the multimeter may be destroyed.
8
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.
‰
ALWAYS discharge filter capacitors in power supplies and disconnect the power when making resistance or diode tests.
9
WArninG! Voltage checks on electrical outlets can be difficult and misleading because of the uncertainty of connection to the
‰
recessed electrical contacts. other means should be used to ensure that the terminals are not "live".
do not use the multimeter in a potentially explosive atmosphere.
8
do not operate the meter unless the back cover and the battery and fuse doors are in place and fastened securely.
if any abnormal readings are observed, the multimeter must be checked out by an authorised technician.
9
When not in use, store the multimeter carefully in a safe, dry, childproof location out of direct sunlight. storage temperature range -20°c
9
to 60°c.
AlWAYs turn off the power and disconnect the test leads before opening the doors to replace the fuse or batteries.
9
the user shall ensure that test probes are correctly selected in order to prevent danger. Probes shall be selected to ensure that
9
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.
note:the warnings, cautions and instructions referred to in this manual cannot cover all possible conditions and
situations that may occur. it must be understood that common sense and caution are factors which cannot be built into this product, but
must be applied by the operator.

multimeter - 11 function
model no:
this symbol adjacent to another symbol, terminal or operating device indicates that the operator must refer
to an explanation in the operating instructions to avoid personal injury or damage to the meter.
this WArninG symbol indicates a potentially hazardous situation, which if not avoided, could result in death
or serious injury.
this cAution symbol indicates a potentially hazardous situation, which if not avoided, may result damage
to the product.
This symbol, adjacent to one or more terminals identifies them as being associated with ranges that may,
in normal use, be subjected to particularly hazardous voltages. for maximum safety, the meter and its test
leads should not be handled when these terminals are energized.
this symbol indicates that a device is protected throughout by double insulation or reinforced insulation.
