SAFETY WARNINGS

 

The following safety information must be observed to insure 

maximum personal safety during the operation at 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-energised and isolated before 

carrying out resistance tests. 

  The rotary selector switch must only be turned 

after 

removing test connections. 

  All 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.
