7.4  Resistance Measurement

 

 

1.  Press the POWER button for a long time to turn on the instrument.  
2.  Press the D/Q/

Θ

/ESR button until “R” is displayed on the screen to select 

inductance measurement.  

3.  Insert  a  resistor  into  test  slots  or  connect  a  tested  resistor  through  a 

proper  test  accessory  (e.g.,  banana  plug-crocodile  clip  test  leads,  test 
fixture or SMD test tweezers). See figures 15 below.  

 

4.  Press  FREQ  button  until  the  desired  test  frequency  is  displayed  on 

screen.  

5.  Press the L/C/R/Z button to select the desired secondary parameter.  
6.  Read the readings on LCD for resistance measured values.  

 

NOTE: 

The meter uses an AC signal for

 

measurement of resistance, so what the test 

result shows is AC resistance property instead of DC resistance property.
