Safety Regulations
1 Safety Regulations
•
Safety warnings and precautions must be read and understood before the
instrument is used. They must be observed during use. Operating
electrical devices implies that parts of the device carry dangerous
voltages. Disregarding warning notices may lead to serious physical
injury and material damage. For example: touching the key tips.
•
This measuring device is only to be installed and operated by qualified
personnel and according to the technical data in compliance with the safety
precautions and regulations set forth below. Additionally, the use of this
equipment requires compliance with all legal and safety regulations pertaining
to each specific application. Similar regulations apply to the use of accessories.
•
Test leads, prods and crocodile clips must be in good order; clean, and with no
broken or cracked insulation
•
Replacement fuses must be of correct size, type and rating
•
It can be assumed that safe operation is no longer possible if the device
•
-
shows visible damage,

Safety Regulations
The instrument has been designed to comply with IEC1010-2-032 Installation
Category (Overvoltage Category) III 600V Pollution degree 2 and
UL 3111-1. The instrument conforms with the EEC Low Voltage Directive
73/23/EEC and 93/68/EEC.
IEC 1010 is a safety standard which has the following features:
•
Installation categories I to IV relate the maximum working voltage to overvoltage
transients that can be expected in the measuring environment. For the
instrument, 600V CAT III, the maximum expected transients must not exceed
6kV peak.
•
In a pollution degree 2 environment the internal design of the instrument can
cope with transient conductivities due to condensation.
Safe operation of the instrument is the responsibility of the operator who
must be suitably qualified and/or authorised as defined above. Users of this
equipment and or their employees are reminded that Health and Safety
Legislation requires them to carry out valid risk assessments of all electrical
work, so as to identify potential sources of electrical danger and risk of
electrical injury such as from inadvertent short circuits. Where the
assessments show that the risk is significant, then the use of fused test leads
constructed in accordance with the HSE guidance note GS38 ‘Electrical Test
Equipment for use by Electricians’ is advised.
If the instrument is used in a manner not specified by the manufacturer, then the
protection provided by the equipment may be impaired.
Maximum Safe Voltage
Voltage:- 600V MAXIMUM AC RMS or DC between live conductor and ground.
600V MAXIMUM AC RMS or DC between V and COM terminals and a maximum
frequency of 1kHz.
Important Information
•

Upkeep and Maintanance
9 Upkeep and Maintenance
If the instrument is operated and handled properly it does not need specific
maintenance and service. Maintenance work must only be undertaken by trained
and qualified staff and during the warranty period only by authorized service
centres.
Recalibration
As an additional service we offer a regular inspection and calibration of your
instrument. Upon request and for a fee we can supply full test calibration certificates
Storage
In case the instrument is either not used or stored for a longer period, remove
batteries and keep them separately beforehand to avoid possible damage by
leaking battery electrolyte.
Service
This instrument has been manufactured and tested according to the latest
technological innovations and in compliance with the quality assurance system
DIN ISO 9001.
If there should still be reason for complaint please refer to your nearest service
centre, giving a detailed description of the defect by using the enclosed service
card and including a copy of the invoice or the delivery note. If the instrument is
operated as agreed we guarantee fault free function of the instrument for a period of
2 years years after the date of the first end-user purchase. This warranty does not
apply to any damage caused by improper treatment or operation or by
impermissible overload.
Packing
For shipping use the original packing only. The manufacturer doesn't accept any
claims for damage that might have occurred through inappropriate packing.
