BP Measurement (BLACK button)
Place the hood with the sealing list making a proper seal around the valve. Start with or
without the throttle ring and press the BLACK button (button on the side). SWF 125D will
wait 2sec to let the flow stabalize in the flow capture, the display will show ”P1” (Point 1)
and start to count up from 0 to 2 (the stabilization time). After that it will make a
measurement for 5sec during wich the display will show the measured value. When
finnished ”P2” (Point 2) will be shown in the display. Within 1 minute Point 2 need to be
measured otherwise SWF 125D will return to Point 1. Remove or put on the throttle ring
and press the BLACK button again, SWF 125D will repeat the same procedure as for P1.
When finnished the display will show the True value without any influence by the flow
capture. If the value is flashing it means that something is wrong and the value might not
be correct, if so please make a new measurement. By pressing the GREY button the
lowest measurement (with throttle ring) of the two points are displayed for 2sec before it
return to the true value again. By pressing the BLUE button the higher of the
two points will be displayed for 2sec.
Save measurement (BLACK button hold down)
When P1 and P2 is measured the measurement can be stored by holding down the
BLACK button for 2 sec. The display will show which note number (ex. n.001 = Note 1) the
measurment is saved in the note book and then returns to measuring mode. If you don’t
want to save the measurement just press the BLACK button and you will return to
measurement mode without saving.
FF Mode (Flow Factor)
It’s possible to multiply the flow with a flow factor. Flow factor 1.00 will not alter the flow.
This can be used to compensate for example a leakage. Warning: Changing to anything
else than 1.00 will alter the reading from calibration certificate. If in BP Mode and the
GREY button is pressed the display will show F1.00 (or the value of flow factor that the
instrument is set to).
FF Measurement (BLACK button)
To measure with the flow factor displayed (example F1.10 will multiply measured flow with
1.10 and display the result) press BLACK button, a * flashing will be shown to indicate that
you are in FF-mode. To change FFvalue hold down the BLACK button for 2 sec when
F1.00 is shown. The first digit will start flashing, change value by pressing GREY or BLUE
button.
When correct value is choosen confirm by press the BLACK button and the second digit
will start flashing, reapet the same procedure with the second and third digit. After the third
digit is confirmed the instrument will go to measuring mode (flashing * will be shown in
display). To return to BP Mode press GREY button 3 times (First press will show FX.XX,
second will show notE and the third will take you to BP mode).
