Function
Various additional functions are available for easy measurement, switch operation and check of measured values suitable for the
conditions of the measured fluid.
Auto shift function
Anti-chattering function
Key lock function
Peak hold function
Bottom hold function
Zero out function
Unit conversion (for overseas use)
Can correct the pressure set point value of switch output according to fluctuations in the primary pressure.
Prevents malfunction due to sudden fluctuations in the primary pressure by adjusting the response time.
The key board operation can be locked to prevent incorrect operation on the operation switch.
Can retain the maximum pressure value displayed during measurement.
Can retain the minimum pressure value displayed during measurement.
The pressure display can be set at zero when the pressure is open to the atmosphere.
Can convert the display value (for overseas use only).
