Pressure Converter (P-P) Task - GE Druck DPI 610 User Manual

Taking Measurements
Pressure Converter (Pressure to Pressure) Task
Select the P-P task from the task menu and connect the UUT to the calibrator as shown
below. Testing a converter requires one pressure to be applied to the unit under test
(UUT) and another (converter output) to be measured. The additional measurement is
provided by the external transducer option.
Method
• Connect the UUT to the calibrator and plug the external transducer into the
calibrator as shown below.

A - External pressure source (indicator instruments only)
B - Pressure regulator
D - Pressure to pressure device
• Press the TASK key and select the P-P task. Providing the external transducer has
been calibrated and its parameters stored in the calibrator, the display shows
External pressure in the input window and calibrator Output pressure in the output
window. If an error message "NO SENSOR OR CAL INVALID" is displayed, this
indicates that the external transducer has not been entered and/or calibrated with
the calibrator. Refer to page 45 for details of adding an external transducer. If an
external transducer change is made, switch the calibrator off and then on to load
new transducer data.
• If required, select the input and output units as described on page 10.
• If applicable, turn on Cal Mode and set-up test parameters as detailed on page 11.
Note: Match pressure ranges to give required accuracy and avoid overpressure. If
external pressure is required as the output and internal pressure the input, use
ADVANCED mode for this set-up.
