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