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 multimeter, please observe all normal safety rules concerning:
Protection against the dangers of electrical current.
Protection of the meter against misuse.
9
Full compliance with safety standards can only be guaranteed if used with the test probes 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 application and limitations of the multimeter as well as the potential hazards.
IF IN ANY DOUBT CONSULT
A QUALIFIED ELECTRICIAN.
9
Before commencing testing, follow instructions below and select the correct input sockets, function and range on the multimeter.
9
When the meter is connected to a circuit,
Do not
touch any unused meter terminals.
9
When the magnitude of the value to be measured is unknown beforehand, set the range selector to the highest value available.
9
Before rotating the range selector to change functions, disconnect test probes from the circuit under test.
Warning! never perform resistance, transistor, diode or continuity measurements on live circuits.
9
Always take care when working with voltages above 60V dc or 30V ac rms. These voltages are considered harmful.
Warning! use eXtreme caution
when working with high voltages.
9
Always keep fingers behind the probe barriers whilst measuring and
Do not
use when hands are wet..
9
Before attempting to insert transistors for testing, ensure that the test probes have been disconnected.
9
Components should not be connected to the transistor socket when taking voltage measurements with the test probes.
8
Do not
test voltages above 600V ac or 1000V dc - the circuitry of the multimeter will be destroyed.
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.
9
alWays
discharge filter capacitors in power supplies and disconnect the power when making resistance or diode tests.
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”.
8
Do not
use the multimeter in a potentially explosive atmosphere or where flammable material is present.
9
only
operate the multimeter when the back cover is in place and fastened securely.
9
If any abnormal readings are observed, the multimeter must be checked out by an authorised technician.
9
alWays
turn off the multimeter and disconnect the test probes, before opening the back cover to replace the fuse or battery.
9
When not in use, store the multimeter carefully in a safe, dry, childproof location out of direct sunlight. If storing for a long period of time,
remove the battery. Storage temperature range: -20°C to 60°C.
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.
