Double insulation.

 

Application around and removal from uninsulated hazardous 

live conductors is permitted.

This symbol, adjacent to a terminal, indicates that, under 

normal use,hazardous voltages may be present.

This symbol, adjacent to another symbol or terminal, indicates 

the user must refer to the manual for further information.

1.1. lnternational Safety Symbols

•   Set the function switch OFF when the meter is not in use.

•   Do not exceed the maximum allowable input range of any function.

1.3. WARNINGS

1.2. SAFETY NOTES

•   Remove the battery if meter is to be stored for longer than 60 days.

•   Set function switch to the appropriate position before measuring.
•   When measuring volts do not switch to current resistance modes.
•   Do not measure current on a circuit whose voltage exceeds 600V.

•   Do not apply voltage to meter when resistance function is selected.

•   When changing ranges always disconnect the test leads from the circuit 

under test.

1.4. CAUTIONS

!

  Improper use of this meter can cause damage, shock, injury or death. 

Read and understand this user manual before operating the meter.

!

  Always remove the test leads before replacing the battery or fuses.

!

  Inspect the condition of the test leads and the meter itself for any 

damage before operating the meter. Repair or replace if damaged before 
use.

!

  Use great care when making measurements if the voltages are greater 

than 25VAC RMS or 35VDC. These voltages are considered a shock 
hazard.

!

  Always discharge capacitors and remove power from the device under 

test before performing Diode, Resistance or Continuity tests.

!

  Voltage checks on electrical outlets can be difficult and misleading 

because of the uncertainty of connection to the recessed electrical 
contacts. Other means should be used to ensure that the terminals are 
not "live".

!

  If the equipment is used in a manner not specified by the manufacturer, 

the protection provided by the equipment may be impaired.
