Pay attention to the negative sign during the enter of the reference value.
Prevent offset during calibration
Pay attention that there is no fluid in the tubing to the manometer.
3.
Clamp tubing at filter degassing pump
FEP
inlet.
4.
Clamp tubing between degassing bypass valve
VEB
and degassing
pressure sensor
PE
and pull off tubing from the degassing pressure sensor
PE
.
5.
Connect a manometer and a syringe to the
PE
sensor, using a Y-piece and
extra tubing.
If required.
6.
You can set the measurement unit to mbar with the
key if you
want to perform a calibration in mbar.
PE Calibration Point -400 mmHg
–530 mbar
7.
Press Degassing Pressure PE
key.
8.
Use a syringe to create a negative pressure of (reading on manometer
display):
•
-400 mmHg
±
10 mmHg
•
-530 mbar
±
13 mbar
9.
Press
key.
10.
Enter the stable value from the manometer as reference value.
Wait until digits are stable.
11.
Confirm with
key.
PE Calibration Point -100 mmHg
–130 mbar
12.
Use syringe and create a negative pressure of (reading on manometer
display):
•
-100 mmHg
±
10 mmHg
•
-130 mbar
±
13 mbar
13.
Press
key.
14.
Enter the stable value from the manometer as reference value.
Wait until digits are stable.
15.
Confirm with
key.
16.
Confirm and store complete calibration procedure with
key.
Note:
The calibration data is saved only after the bit sequence 0-1-0 (for
detailed information see 4.8.3.1 General Calibration Information).
17.
Remove calibration devices.
18.
Reconnect tubings.
19.
Check function in TSM menu Test 1.16 Pressure Water Part:
•
Open degassing bypass valve
VEB
and set speed of degassing pump
EP
to 1,500 rpm
•
PE
should show a of approx. < -35 mmHg/-50 mbar
•
Close
VEB
and increase speed to 2,100 rpm
•
PE
should show a value of approx. < -500 mmHg/-670 mbar
