7.9. Continuity Measurements

 

3. Use the MODE button to select continuity "   ". The display icons will 

change when the MODE button is pressed.

 

4. Touch the test probe tips across the circuit or component under test.

 

2. Set the function switch to the  

Ω

         position.

 

5. lf the resistance is < 50

Ω

, a tone will sound.

 

1. lnsert the black test lead into the negative COM terminal and the red 

test lead into the 

V      CAP TEMP Hz%

 

Ω

 positive terminal.

2.  Press and hold the 

MODE/VFD

 key and turn the selector switch to turn 

the system on, the auto power off function will be cancelled.

7.11. MODE/VFD (Variable Frequency Drive)

1.  To freeze the LCD reading, press the 

Hold/Flashlight

 button. While 

data hold is active,the 

HOLD

 icon appears on the LCD. Press the 

 

 

button again to return to normal operation.

2.  lf AC voltage is present, the detector light will illuminate.

1.  Touch the probe tip to the live conductor or insert into the live side of 

the electrical outlet.

 

NOTE:

 The conductors in electrical cord sets are often twisted. For best 

results, rub the probe tip along a length of the cord to assure placing 
the tip in close proximity to the live conductor.

3.  Press the 

Hold/Flashlight

 button to turn the Flashlight on. Press again 

to turn the Flashlight off.

1.  Press 

MODE/ VFD

 key to select the double measurement functions. 

This key is active in 

V      CAP 

Ω

   position to select among resistance 

test, diode test, continuity test, HZ%, and in Temp position to select 
between °F or °C.

7.10. Non-Contact AC Voltage Measurements

 

WARNING:

 Risk of Electrocution. Before use, always test the Voltage 

Detector on a known live circuit to verify proper operation

 

NOTE:

 The detector is designed with high sensitivity. Static electricity or 

other sources of energy may randomly trip the sensor. This is normal 
operation.

3.  Press and hold the MODE/VFD key for 2 seconds to switch to VFD.

7.12. HOLD/Flashlight

2.  The LCD is equipped with backlighting for easier viewing, especially in 

dimly lit areas.
