1 Zero-point calibration condition: Under atmospheric pressure
2 Yokogawa’s pressure standards accuracy is excluded.
3 Conditions of response time measurement:
The response time is defined as the time for the readout to settle within ±1% of the full scale from the
time when the positive pressure is released to atmosphere when it is at its full-scale value
(where the input unit is under no load).

CA700-E-01: Positive pressure 200 kPa and negative pressure 80 kPa
CA700-E-02: Positive pressure 1000 kPa and negative pressure 80 kPa
CA700-E-03: Positive pressure 3500 kPa and negative pressure 80 kPa
5 Liquid temperature 5 to 50°C
Pressure switch test
Holds the pressure valued at the time the port switches between open and close.
Measures the resistance between ports when they are closed (measurement current < 1 mA)
Resistance measurement range 0 to 2.000 kΩ
Tilt Alarm
The zero adjustment indicator blinks when the orientation of the CA700 changes by approximately
10 degrees or more after the previous zero adjustment.
If the external pressure sensor selected as a function changes in position of about 10 degrees or
more after zero adjustment, the zero adjustment indication blinks.
