5.5 Measuring Pressure

Warning

To avoid a violent release of pressure in a pressurized system, shut off the valve and slowly bleed off the pressure before you attach the pressure module to the pressure line.

Caution…

 To avoid damaging the pressure module from overpressure, never apply pressure

above the rated maximum printed on the module.

 To avoid damaging the pressure module from corrosion, use it only with specified

materials. Refer to the pressure module documentation for material compatibility.

To measure pressure, follow the principle of navigating through the functions described in the guidelines in section 4.2 and proceed as follows:

1. Connect the pressure module to the ASC-400 calibrator, as shown below in Figure

Note…

The APM might take a while to start up. The module is a complete pressure measuring system with a microcontroller system inside.

5.5.1 Zeroing with Absolute Pressure Modules (APM S, H and Mk.II)

To zero, adjust the calibrator to read a known pressure, such as barometric pressure. To adjust the calibrator, follow the principle of navigating through the functions described

in the guidelines in section 4.2 and proceed as follows:

1. Select either the upper or lower display to work from.

2. Select “Pressure” from the Upper or Lower Mode list.

3. Press to activate the Zeroing.

ZERO

4. The calibrator stores the Barometric zero offset in non-volatile memory.

The zero offset is stored for one absolute pressure module at a time. If a new

absolute module is connected this process must be repeated.

5.5.2 Using the BARO Module (optional)

1. The BARO barometer option in the ASC-400 calibrator has 2 functions.

 Working as a high accuracy barometer

 Applying the barometric pressure value to the measurement of a pressure

module (APM) allowing any gauge APM to be used for absolute measurements. This system is superior to ordinary absolute sensors, as the working sensor is gauge and can be zeroed at any time, compensating for potential drift.

128797 03 2015-04-22 26

2. If the BARO option is mounted, the pressure type field becomes active and

pressure type can be selected.
