OPERATION 

WARNING

: Risk of electrocution. 

High-voltage circuits, both AC and DC, 

are very dangerous and should be 

measured with great care. 

If  “1”  appears  in  the  display  during  a  measurement, 

the value exceeds the range you have 

selected. Change 

to a higher range.   

NOTE

:  On  some  low  AC  and  DC  voltage  ranges,  with  the 

test leads not connected to a device, the display may show a 

random,  changing  reading.  This  is  normal  and  is  caused  by 

the high-input sensitivity. The reading will stabilize and give 

a proper measurement when connected to a circuit. 

 

BACK LIGHT BUTTON

 

The 

BACK  LIGHT  BUTTON

  is  used to turn  the  back light on 

Only. To extend the battery life, The back light will be turned off   

automatically within around 3 seconds 

 

DC VOLTAGE MEASUREMENTS 

CAUTION: 

  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. 

1.

 

Set the function switch to the V DC position (“mV” will 

appear in the display). 

2.

 

Insert  the  black  test  lead  banana  plug  into  the  negative 

(COM)  jack  and  the  red  test  lead  banana  plug  into  the 

positive (V) jack. 

3.

 

Touch the test probe tips to the circuit under test. Be sure 

to observe the correct polarity (red lead to positive, black 

lead to negative). 

4.

 

Read  the  voltage  in  the  display.  The  display  will 

indicate  the  proper  decimal  point  and  value.  If  the 

polarity is reversed, the display will show (-) minus 

before the value.
