GSAFETY WARNINGS
The following safety information must be observed to insure maximum personal safety during the operation at this meter:
n Do not use in wet environments
n Measurements beyond the maximum selected range must not be attempted.
n Extreme care must be taken when measuring above 50 V, especially on live bus-bars.
n To measure voltage, the instrument must not be switched to a current or resistance range, or to the diode check or buzzer position.
n Circuits must be de-energised and isolated before carrying out resistance tests.
n The rotary selector switch must only be turned after removing test connections.
n All external voltages must be disconnected from the instrument before removing the battery.
n Test leads and prods must be in good order, clean, and with no broken or cracked insulation.
n UK Safety Authorities recommend the use of fused test leads when measuring voltage on high energy systems.
n Replacement fuses must be of the correct type and rating.
n The instrument must not be used if any part of it is damaged.
n Check for correct instrument operation by testing a known voltage before and after use. Do not use if misleading results are obtained.
n Warnings and precautions must be read and understood before an instrument is used. They must be observed during the operation of this instrument.

Users of this equipment and/or their employers are reminded that National 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 inadvertent short circuits. Where the assessments
show that the risk is significant then the use of fused test leads may be appropriate.
NOTE
THE INSTRUMENT MUST ONLY BE USED BY SUITABLY TRAINED AND COMPETENT PERSONS.
