value  is  more  than  1  MΩ,  the  reading  takes  a  few  seconds  to  stabilize,  which  in  high 

resistance mode is normal.

 

2. When the input is open, the overload condition is displayed.

 

3. When measuring the on-line resistance, make sure that all the power of the circuit under 
test are turned off and all the capacitors are fully discharged.

 

4. Do not input voltage in the resistance range.

 

 

Diode test

 

1. Insert the black probe to "COM" and the red probe to "V/Ω"

 (note that the polarity of the 

red probe is "+"); 
2.  Put  the  range  switch  to  "    ".  Connect  the  black  probe  to  the  cathode  and  the  red 
probe to the anode. On the display will be shown the approximative forward voltage drop. 
 

Non-contact voltage detection (with NCV instruments)

 

1. Set the function range switch to the NCV range position. 
2. Close the instrument to > 100 VAC 
3.  When  the  instrument  distance  <  30  mm,  the  instrument  within  the  non-contact  voltage 
detection alarm will start to beep. 
 

Data retention function

 

Press the (right) key, then the measurement data will be locked, and will be easy to read and 
record. Then press the right button to reset the instrument to restore the measurement. 
 

Back-light display

 

Press the "left" button and the back-light will be turned on for about 10 seconds. 
 

Instrument maintenance

 

This instrument is a precision instrument, the user should not arbitrarily change the circuit. 

 
Note

1. Do not connect voltages above 500 VDC or 500 Vrms; 
2. Do not measure the voltage value 

when the range switch is in resistance mode "Ω";

 

3. Do not use the multimeter for testing when the battery is not installed or the back cover is 
not installed; 
4. Before replacing the battery of fuse, remove the test leads from the test point and turn off 
the power switch. 
 

Fuse replacement

 

When replacing the fuse, use the same fuse as the model type.
