SAFETY WARNINGS
These safety warnings must be read and understood before the instrument is used.
Whenever possible, circuits should be de-energised before testing.
If it is impossible to de-energise the circuit, (e.g. high voltage batteries cannot be switched off while their connections are tested) the user must
be aware of the dangers. The instrument terminals will become live when connected to the circuit. Therefore when used on hazardous voltages
custom Megger DH6, DH6-C test leads must be used.
Testing inductive circuits can be hazardous:
After testing an inductive load there will be an amount of energy stored in the inductance. This energy is released in the form of a discharge
current. Disconnecting an inductive load while current is still flowing will cause a high voltage arc, which is a danger to both the user and the item
under test.
Although the DLRO10 and DLRO10X are not designed as transformer ohmmeters the DLRO10 is fitted with a DISCHARGE lamp, marked ‘I’, which
indicates that current is flowing in the C1-C2 loop. This lamp will flash at end of a test on an inductive load while a discharge current is still flowing
and will stop flashing when the current has decayed to less than 1mA. DLRO10X uses a message on the display to achieve this.
For testing large inductive resistances the current carrying leads should be connected securely to the item under test before starting the test. It is
not recommended that duplex handspikes be used to carry out tests on inductive loads.
If inadvertently using the DH4 handspikes on an inductive load, the L1 lamp on the handspikes will flash amber while discharge current flows,
thereby duplicating the function of the ‘I’ lamp on the instrument. It is important to maintain contact until the L1 light stops flashing amber and
turns green indicating the end of the test.
This product is not intrinsically safe. Do not use in an explosive atmosphere.
This instrument contains a lithium-ion high energy battery pack.
Do not pierce, damage, disassemble or modify the battery.
The battery contains safety and protection devices, which if tampered with may cause the battery to generate heat, rupture or ignite.
If a battery module is suspected to contain a faulty battery cells - do not ship the faulty battery module, either separately or inside an instrument.
The instrument must be set to OFF and the lid must be installed and securely closed before the instrument is shipped.
Do not heat or dispose of the battery in a fire.
Do not subject the battery to strong impact, mechanical shock or excessive heat.
Do not short-circuit or reverse the polarity of the battery pack.
Please note. The neck strap is specifically designed to break if subjected to a strain of approximately 50 kg.
