Other symbols 

While testing the insulation resistance, the symbol “

” flashes frequently if the voltage is over 

30 V. 

: While testing t

he insulation resistance, the symbol “

” flashes frequently and the buzzer 

warns continually if the outside voltage is over 30 V. T

he symbol “

” is indicated while LOΩ≤35Ω 

and the buzzer warns continuously. 

LOCK

: Push down the “LOCK” button while you are testing the insulation resistance. The meter 

will enter insulation resistance status and the symbol “

” is indicated. 

LOBAT

: The display shows “LOBAT” when the voltage drops below 7.5 V. 

HOLD

: The current value is held. 

V, 

MΩ, Ω

: The measured dimension units 

 

Operation  

 

Risk  of  electrocution.  High-voltage  circuits,  both  AC  and  DC,  are  very 

dangerous and should be measured with great care.

 

 
• ALWAYS turn the function switch to the OFF position when the meter is not in use. 
• If “OL” appears in the display during a measurement, the value exceeds the range you have 
selected. Change to a higher range. 

3.1 

DC Voltage Measurements 

 

Do not measure DC voltages if a motor on the circuit is being switched ON or 

OFF. Large voltage surges may occur that can damage the meter.

 

 

• Set the function switch to the green VDC

 

position.

 

• Insert the black test lead banana plug into the negative

 

COM 

  jack. Insert the red test lead banana plug into the positive V 
  jack. 
• Touch the black test probe tip to the negative

 

side of the 

  circuit. Touch the red test probe tip to the positive side of the 
  circuit. 
• Read the voltage in the display.
