Set Pressure Range and Rated Pressure Range
Functions
Set the pressure within the rated pressure range.
The set pressure range is the range of pressure within which setting is possible.
The rated pressure range is the range of pressure that satisfi es the specifi cations (accuracy, linearity, etc.) of the switch.
Although it is possible to set a value outside the rated pressure range, the specifi cations cannot be guaranteed even if the value stays within the set pressure range.

Sub screen setting function The display of the sub screen can be selected.
Auto-preset function This function calculates a rough set value automatically based on the on-going operation.
Display value fine adjustment function
Evens out deviations in the displayed value
Peak value indication function Can retain the maximum pressure value displayed during measurement
Bottom value indication function Can retain the minimum pressure value displayed during measurement
Key-lock function (Selectable secret code)
The keyboard can be locked to prevent the accidental operation of the operation switch.
Zero-clear function The pressure display can be set to zero when the pressure is open to the atmosphere.
Error indication function This function displays the error location and content when a problem or error has occurred.
Anti-chattering function Prevents possible malfunctions due to sudden fluctuations in the primary pressure by adjusting the delay time
Unit selection function Can convert the display value
Power-saving mode Reduces power consumption
Display resolution switch function
Converts the display resolution from the normal value of 1/1000 to 1/100
Can reduce flickering of the monitor
kPa ↔ MPa switch function Converts the unit between kPa and MPa
Copy function

The settings of the master sensor can be copied to the slave sensors.
Auto-shift function
∗
