5-8 Pressure calibrator operation (DPI 620)

K0457 - [EN] English

4.

To set the necessary pressure or vacuum for the calibration,
use the specified procedures for your PV 62x pressure
station*.

* Reference

•

PV 621 models: see Chapter 2 (Pneumatic pressure
operation (PV 621))

•

PV 622 models: see Chapter 3 (Pneumatic pressure
operation (PV 622))

•

PV 623 models: see Chapter 4 (Hydraulic pressure
operation (PV 623))

5.3.7 Example procedure: Transmitter calibration

1.

Assemble the pressure calibrator with the correct PM 620
module and PRV (if applicable); see Section 5.2.3.

2.

Set the applicable software options; see Section 5.3.1
(Procedure overview). This example shows two functions:

•

Channel 2 (CH2) is set to measure current with 24V loop
power.

•

Pressure (P1) is set to measure the pressure supplied by
the pressure station.

3.

To attach the device under test, use the specified
procedures for your PV 62x pressure station*.
