3.1.2.1

 

Introduction of the interface 

 

Scrollbar

—show the relative distance between sensor and rebar. 

Blank—no rebar in sensing range of sensor 

Increase—sensor is moving towards rebar 

Decrease—sensor is moving away from rebar 

 

 

Signal value

— the larger present sensor receiving signal amplitude, the closer to rebar. 

 

 

 

Cur.  Cover

—the current thickness of cover, the equivalent distance (unit, mm) between sensor and 

rebar,  the  larger  the  equivalent  value,  the  farther  it  is.  When  equivalent  value  exceeding 

measurement ranges of sensor, it is 0 and the minimum value of current thickness is the thickness 

of cover. (If users used data correction, it only shows measurement value not corrected one) 

 

 

Cover

—display  of  measurement  value  (unit,  mm)  of  thickness  of  concrete  cover  automatically  (If 

users used data correction, it shows the corrected value). 

 

 

Dia. 

display  of  measurement  diameter  of  tested  rebar  (unit,  mm).  pressing 

 

key  for 

measurement of diameter and thickness of cover (There is no need for the input of the diameter of 

tested  rebar),  please  see  detail  description  in  chapter  3.4.1.3.  After  testing  the  diameter,  it  will 

display as follows: 

Cover: 

*** ( measurement of the thickness of cover of rebar) 

Dia.:  ***  (measurement of rebar diameter) 

 

 

Sav. Num

— it is the stored amount of thickness of cover for present object. 

 

 

 

Qualification  rate

—the  rate  of qualified points of  all  the stored thickness  values  in  current  object 

according to the specification of GB50204-2002.
