 button: 

In SETUP mode, press the 

 button to increment value by 1. Press and hold the 

 

button for over 2 seconds to increment value swiftly. In Recall mode, press the 

 button to 

display the next stored data location. 

3. 

SELECT button: 

In SETUP mode press the 

SELECT

 button to select HI (Limit) or LO (Limit) 

or display cable resistance per foot or meter 

4. 

 button: 

In SETUP mode, press the 

 button to decrement value by 1. Press and hold the 

 button for over 2 seconds to decrement value swiftly. In Recall mode, press the 

 button to

5. 

ZERO / RECALL button: 

In resistance mode, zero the range before making measurements. 

Press the 

ZERO / RECALL

 button to enter Relative mode (the present readings will be reset to 

zero), or press the

 ZERO / RECALL

 button for over 2 seconds to exit the Relative mode. In 

SETUP mode, use this button to recall the pre-stored sets of HI limits, LO limits and resistance 
per unit. 

6. 

START / STOP button:
