DLRO2 and DLRO2X safety warnings
These safety warnings must be read and understood before the instrument is used. Retain for
future reference.
Warning: This instrument must be operated only by suitably trained and competent people.
Protection provided by the instrument may be impaired if it is not used in a manner specified
by the manufacturer.
Local Health and Safety Legislation requires users of this equipment and their employers to carry out
■
valid risk assessments of all electrical work to identify potential sources of electrical danger and risk
of electrical injury such as inadvertent short circuits. Where the assessments show that the risk is
significant then the use of fused test leads may be appropriate.
If battery power is lost during the test, then the user will no longer be warned that the load is being
■
discharged. The user must check by independent means that the load is discharged before breaking
connection.
Disconnect all test leads and switch the instrument OFF before opening the battery. Covers must be in
■
place before reconnecting the test leads.
Ensure every cell in the battery compartment is of identical type. Never mix rechargeable and non-
■
chargeable cells.
This product is not intrinsically safe. Do not use it in an explosive atmosphere.
■
Protection provided by the instrument may be impaired if it is not used in a manner specified by the
■
manufacturer.
The voltage warning function will operate only if the instrument is switched on and working correctly.
■
In the absence of an indication do not assume that there are no hazardous voltages
The voltage indicator and current discharge features must be regarded as additional safety features and
■
MUST not substitute the normal safe working practice which MUST
be followed.
The instrument must not be used if any part of it is damaged or if the terminal shutter is missing.
■
The circuit under test must be switched off, de-energized, securely isolated and proved dead before
■
test connections are made.
Circuit connections, exposed conductive parts and other metalwork of an installation or equipment
■
under test must not be touched during testing.
Only "Megger" approved test leads with right-angled instrument connectors must be used with this
■
instrument. Test leads must be at least 1 m in length and provide a total loop impedance ≥ 26 mΩ.
When inductive loads are measured it is essential that the current carrying leads are securely clamped
■
to the item being tested and that they are not removed before any stored charge has been discharged
at the end of the test. Failure to comply with these instructions might result in an arc being produced
which might be dangerous for the instrument and the operator.
All test leads, probes and crocodile clips must be in good order, clean, and with no broken or cracked
■
insulation.
Verify the integrity of the test leads before use.
The safe maximum limit of a measurement connection is that of the lowest rated component in the
■
measurement circuit formed by the instrument, test leads and any accessories.
Ensure that hands remain behind finger guards of probes and clips.
