Zero point calibration of the Pirani sensor element
The zero point of the Pirani sensor
element is calibrated at
0.001 mbar.
Please ensure that this pressure is
applied to the sensor during the
calibration procedure.
Fig. 13 Calibration mode: calibrating 0.001 mbar
Calibration mode is called by pressing both the < set > and <
↑↑↑↑
> keys simultaneously.
The calibration mode is indicated in the display by two triangles in front of the measured va-
lue.
•
Select the pressure to be calibrated (in this case 0.001 mbar) with the <
↑↑↑↑
> and <
↓↓↓↓
>
cursor keys.
•
The cursor key must be held up to 0.001 mbar in the display appears.
•
Make sure that a pressure of 0.001 is applied to the sensor.
•
Accept the measured value by pressing the < set > key.
Please press the function key < F > if you want to leave calibration mode prematurely with-
out taking over the new calibration value, the device then switches back to measuring mode.
6.3.4
End point calibration of the Pirani sensor element
The end point of the Pirani sensor
element is calibrated at 10 mbar.
Please ensure that this pressure
is applied to the sensor during the
calibration procedure.
Fig. 14 Calibration mode: calibrating 10 mbar
Calibration mode is called by pressing both the < set > and <
↑↑↑↑
> keys simultaneously.
The calibration mode is indicated in the display by two triangles in front of the measured va-
lue.
•
Select the pressure to be calibrated (in this case 10 mbar) with the <
↑↑↑↑
> and <
↓↓↓↓
> cursor
keys.
•
The cursor key must be held up to 0.001 mbar in the display appears.
•
Now the cursor key <
↑↑↑↑
> still 2 x briefly press. In the display 10 mbar must appear.
•
Make sure that a pressure of 10 is applied to the sensor.
•
Accept the measured value by pressing the < set > key.
Please press the function key < F > if you want to leave calibration mode prematurely with-
out taking over the new calibration value, the device then switches back to measuring mode.
