1. SAFETY WARNINGS

The following safety information must be observed to    
insure maximum personal safety during the operation          
of this meter:

•  Measurements beyond the maximum selected range must not be 

attempted.

•  Extreme care must be taken when measuring above 50 V, especially on 

live bus-bars.

•  To measure voltage, the instrument must not be switched to a current 

or resistance range, or to the diode check or buzzer position.

•  Circuits must be de-energized and isolated before carrying out 

resistance tests.

•  The rotary selector switch must only be turned after removing test 

connections.

•  External voltages must be disconnected from the instrument before 

removing the battery.

•  Test leads and prods must be in good order, clean, and with no broken 

or cracked insulation.

•  UK Safety Authorities recommend the use of fused test leads when 

measuring voltage on high energy systems.

•  Replacement fuses must be of the correct type and rating.
•  The instrument must not be used if any part of it isdamaged.
•  Warnings and precautions must be read and understood before an 

instrument is used. They must be observed during the operation of this 
instrument.
