Chapter 4 – Functions of the instrument
UM-22100H-U User manual ATEQ D520 Page 60/122
Associated parameters to be adjusted: Max RECOV, Min RECOV.
If in multi measurement instrument configuration the parts are recoverable, the good
part (POK) and bad part (PNOK) outputs are activated simultaneously.
) Select the option and adjust settings if necessary.
2.1.3. 14) P1 – P2 Function
This function allows the taking away of the pressure
measurement of piezo sensor 2 (if installed depending
on options) from that of piezo sensor 1.
CYCLE/Pr:001
PRESS : 18.9 mbar
FLOW : 97.7 ml/s
P1-P2 : 18.9 mbar
) Select the option and adjust settings if necessary.
2.1.3. 15) P1 – P2 Correction
This function can on the basis of the P1 – P2 result (refer to the paragraph above) allow
a correction to be made on the flow result of P1 - P2. Function similar to the function
"pressure correction" paragraph 2.1.3.8.
) Select the option and adjust settings if necessary.
2.1.3. 16) Fill mode
This function gives the choice of three types of fill operation.
a) Standard
With a mechanical regulator
Adjust the value of the fill pressure manually by using the regulator handle during a
"regulator adjust" special cycle.
With an electronic regulator
The fill pressure is adjusted automatically on the value chosen when the test program is
created.
b) Instruction
The operator adjusts an instruction value for the fill pressure and opens the regulator.
When the instruction pressure is reached the fill is stopped.
Associated parameters to be adjusted: I. FILL (Instruction fill).
c) Ballistic
This type of fill allows a fluctuation of the air pressure (filling of highly deformable parts)
and enables an exceeding of the maximum fill threshold without stopping the cycle and
delivering an error message. Never the less, to move into stabilization, the test pressure
must be between the thresholds at the end of the fill.
