Explanation
Measurement Function (Function)
To measure pressure, select one of the following:
P: Input pressure directly to the CA700 to measure pressure.
The following pressure ranges can be measured depending on models:
CA700-01 (200 kPa model):
-80 to 200 kPa (gauge pressure)
CA700-02 (1000 kPa model):
-80 to 1000 kPa (gauge pressure)
CA700-03 (3500 kPa model):
-80 to 3500 kPa (gauge pressure)
EXT P: Use the external pressure sensor to measure pressure.
In addition to pressure (P, EXT P), the following is available.
P LEAK/EXT LEAK: Leak rate (see section 2.2)
DC current and DC voltage can be measured or generated simultaneously while pressure is being
measured (Display2 setting). For details on DC current and DC voltage source and measurement, see
section 2.3 or 2.4.
Measurement Range (for EXT P)
Select the measurement range of the external pressure sensor.
Unit
You can set the pressure unit to mbar, bar, Pa, hPa, kPa, MPa, or atm.
Averaging
The CA700 can take a moving average of the measured values.
Relative and min/max values are calculated using averaged values.
When averaging is set to ON, “AVG” is displayed on the screen.
