                                                              Figure 4. Insulation Resistance Measurement 

1.    According to testing request, tune the function switch to a suitable function 

2.    Connect the electrode of the tested object to the relative terminals of the tester 

3.    When testing a cable, connect “G’ terminal to the protection loop. 

4.    Press “TEST” button to get started the measurement. Read the display after the display stabilized. To make continuous 

measurement, turn the function switch to the right to lock. Turn the function switch to the left to unlock the continuous 
measurement. When pressing the “TEST” button, the high voltage indicator turns red, and the high voltage indication is 
displayed on the LCD. At the same time, the beeper alarms with “tick-tick” sound. If the tested insulation resistance is 5% 
less than the selected range of if there is short circuit, the beeper alarms with a “tick……” long sound.   

5.    Connect the red lead “E” to the circuit of the tested object, and black lead “L” to the ground terminal of the tested object. 

Lead “E” is required to be hung in the air. 

6.    If the LCD displays “1”, it indicates over range operation. Please choose a higher range to get reading. 

Caution 

1.    Pressing the “TEST” button, output terminal “E” will have high voltage output. Be careful to avoid electric shock. 

2.    Before testing, make sure to choose a correct voltage range. Make sure the LCD display is in accordance with selected 

voltage. 

3.  During M

 measurement, the ambient interference or insulation material instability may cause unstable readings. In this 

situation, connect terminal “G” to the shield terminal of the tested object to get stable readings. 

RESISTANCE AND CONTINUITY MEASUREMENT 

1.    Tune the function switch to range 2000

2.    Connect the read lead to “V/

” input terminal and black lead to “G” input terminal. 

3.    Connect the test leads across the tested circuit. The LCD will display the tested data. 

4.    If the tested resistance is less than approx.50

, the beeper alarms. 

Caution 

1.    If the tested resistance is over 2k

 or there is open circuit, the LCD displays “1”. 

2.    When testing a live resistor, to ensure safety, do not proceed testing until the tested circuit is completely powered off and 

all capacitors are fully discharged. 

3.    If testing results have considerable, it may be caused by other live components of the same circuit or by electric potential 

on the two ends of the resistor.
