[F11] Display resolution 

This function is used to change the pressure display resolution. 
This can be used to prevent the digits from flickering on the display. 

 

<Operation> 

Press the

 

 

or

 

 

button in function selection mode to display [F11].

Setting of [F11] Display resolution completed. 

 
 

: It may not be possible to change the resolution depending on the unit of pressure selected.. 

 
The units that allow display resolution to be selected are MPa, kPa, kgf/cm

2

, psi and inHg. 

(The units kgf/cm

2

, bar, psi and inHg can only be set when using a product with unit conversion function.)
