Safety Warnings - Megger BM15 Guia Del Usuario

'Safety Warnings' and 'Working with Capacitive Loads' must be read and understood before the instrument is used. Safety precautions must
n
be observed during use.
The circuit under test must be switched off, de-energised and isolated before any test connections are made.
n
Circuit connections must not be touched during a test.
n
On completion of a test, decaying voltage across the terminals is indicated on the display. Capacitive load circuits must be discharged
n
to below 60 V before disconnecting the test leads.
Capacitive load circuits should be shorted with a shorting link after discharge.
n
Remove the test leads from the instrument before opening the battery compartment.
n
Test leads and crocodile clips must be in good order, clean and with no broken or cracked insulation.
n
The instrument should not be used if any part of it is damaged.
n
U.K. Safety Authorities recommend the use of fused test leads when measuring voltage on high energy systems. See 'Choice of Test Leads'.

CAT II
Measurement category II: Equipment
connected between the electrical outlets
and the user's equipment.
NOTE - The instruments must only be used by suitably trained and competent persons.
Users of this equipment and or their employers 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' should be used. See 'Choice of Test Leads'.
The measurement leads provided with the BM15/MJ15 are rated CAT O, and are to be used for connection to low voltage (<33V) circuits only. Potentially hazardous circuits must
be isolated and verified as safe using a suitably rated instrument before making any measurement connection using unrated leads. The CAT rating of the instrument is the same as
the lowest rated part in the measurement connection.
