 Ultrasonic Thickness Gauge 

29 

 

1)  Press the 

 key to edit the gain setting.  The edit icon will be illuminated 

and flashing. 

2)  Use the 

 

 keys to scroll through the gain settings 

(VLOW, 

LOW, MED, HIGH, VHI)

 until the desire setting is being displayed. 

3)  Press the 

 key to set the gain and return to the measurement screen. 

Note:

  

Pressing the  

 key prior to pressing the 

 

key will abort to the 

measurement screen without saving changes.

 

 

7.2 High Speed Scan 

The High Speed Scan feature of the 

ZX-5

 increases the overall repetition rate to a 

maximum of 140Hz with a high speed screen refresh rate of 25 times a second.  This 
allows for making scanned passes over an arbitrary length of the test material, while 
still maintaining a reasonable representation of thickness over the area or region 
scanned. 
 
The procedure to use the scan feature is outlined below:  
 

High Speed Scan 

 

1)  Press the 

 key to toggle 

SCAN

 on/off.  The display will briefly display the 

status and return to the measurement screen.

 

 

7.3 Alarm 

The

 feature of the 

ZX-5

 provides a method of setting tolerances, or limits, for a 

particular application requirement.  This feature may be used for a variety of
