OPERATION INSTRUCTIONS 

š

 

Operation area condition: This gauge can measure all samples which are equal to or bigger than the probes 
surface area.  

š

 

Curved surface condition: When materials have a curved surfaces like a boiler wall or tubing, the curvature 
radius must be equal to or more than 10mm and the wall thickness must be equal to or more than 3mm.  

š

 

Roughness condition: This gauge is applicable for a wide range of materials. In most cases the supplied 
probe makes very accurate readings. However if the roughness is too big due to rust etc. an error may 
occur. In this case please try to minimise the roughness or select the 2.5MHz probe. If the probe is worn-
out, please contact your local distributor for a replacement probe. 

š

 

Working temperature condition: Material and sound velocity will change along with temperature. In 
normal measurement conditions environment temperature impact can be ignored. The probe is made of 
propylene material. Considering the protection of the probe and its precision we recommend a surface 
temperature of the work piece should not be over 60

o

C otherwise the probe could be damaged. 

š

 

Operation temperature: 0 - 40

š

 

Relative humidity: <90% RH

PREPARATIONS 

1. Turning on your instrument

Connect the probe with the main unit, press ON/OFF to turn on the instrument. The display shows a full screen 
for 0.5 sec with backlight, then a vertical bar is displayed twice circularly, meanwhile the main display area 
shows 0000 to 9999 progressively. After that  the LCD displays the last applied sound velocity with registered 
memory.
