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.
