Equipped with auto-reference / remote zero-adjustment functions,

More precise pressure management is achieved with a minimum of effort

If the reference pressure of the

device changes, two functions

are selectable. One is

auto-reference function, which

partially shift the comparative

output judgment level by the

amount that the reference

pressure shifts. The other is

remote zero-adjustment

function, which can reset the

display value to zero via

external input. These functions

are ideal for places where the

reference pressure fluctuates

wildly, or where fine settings are

required.

Threshold level after applying

auto-reference input

Because the threshold level is fixed for conventional pressure sensors,

changes in the reference pressure result in wrong decisions.

When remote zero-adjustment input is applied, the reference pressure is forced to “0”.

If the reference pressure changes to “20” or “40”, the remote zero-adjustment input

adjusts the reference pressure to “0” every time the reference pressure changes, so

any variation in the filling pressure can be ignored.

When auto-reference input is applied, the reference pressure “30” is

added to the threshold level. If the reference pressure changes to “20” or

“40”, the auto-reference input compensates for this every time by changing

the threshold level, so any variation in the filling pressure can be ignored.

Energy-saving design! Equipped with an ECO mode

This mode lowers the display luminance to cut power consumption

by approximately 30 %. The displays can also be turned off

completely to achieve a power saving of approximately 40 %.

Peak hold and Bottom hold functions

The peak values and bottom values for fluctuating pressures can be

displayed using the dual display.
