6.5  Reference Value and Relative Display

Procedure

1.

  When measured values are displayed on the screen, press 

RELATIVE

 on the CA700 front 

panel.

REL appears on the screen, and a relative value based on the reference value is displayed.
If the reference value is assigned to the measured value, when you press RELATIVE, the measured value 
will become the reference value.

 

   

Displaying the difference relative  

to the reference value 

Difference relative  

to the reference value 

2.

  To return to the normal measurement display, press 

RELATIVE

 again.

Explanation

You can display relative values based on a reference value by setting the reference value to a specific 
value or to the measured value when you press the RELATIVE key.
For details on the reference setting method, see section 2.1.
The following features are disabled while relative values are displayed.
•  Measurement range change
•  Min/Max Display
•  Zero calibration
