Calibrating the Pressure Transmitter
3.1
Connecting to a Pressure Transmitter or
Pressure Switch
• Do not apply pressure exceeding the allowable input range. Excessive pressure may cause
injury or damage to the instrument.
Model
Allowable input
• When joining the connector, using a spanner only on the connector side may break the
inside of the instrument. Be sure to use another spanner on the cut-out of the input port to
tighten the connector.
French
• Ne pas appliquer de pression supérieure à la plage d'entrée autorisée. Une pression
excessive risquerait de provoquer des blessures ou d'endommager l'instrument.
Modèle
Entrée autorisée Pression négative
L'utilisation d'une clé uniquement sur le côté connecteur lors du raccordement du connecteur
risque de casser l'intérieur de l'instrument. Pour serrer le connecteur, veiller à utiliser une
autre clé sur la découpe du port d'entrée.
Connecting a Pressure Transmitter to the CA700
Connect the pressure pump output to the transmitter input and the CA700 input through branching.
To use the external pressure sensor, connect the pressure pump output to the pressure transmitter
input and the external pressure sensor input through branching, and connect the sensor output to the
external pressure sensor connection terminal of the CA700.
Some pressure pumps have two output ports: one for applying pressure and another for the pressure
meter.
Connect the electrical signal from the pressure transmitter to the signal terminal of the CA700. Connect
to the appropriate input terminals on the CA700 depending on the type of output received from the
pressure transmitter.
