The pressure transducer VSP 3000 was adjusted using factory standards, which are
traceable through regular calibration in an accredited laboratory (German Calibration
service) to the German national pressure standard. Depending on the process and/
or on accuracy requirements, check the adjustment and readjust if necessary. For
readjustment, the device has to be adjusted both at atmospheric pressure as well as
under vacuum.
➨
For readjustment, install the pressure transducer in the same orientation in which
it will be operated later on at the application.
➨
Allow the pressure transducer a period of minimum 20 minutes to preheat.
If no adjustment is possible in the current pressure range, ”---- mbar” is displayed.
Adjustment at atmospheric pressure
An adjustment at atmospheric pressure is only possible in the
upper pressure range.
Ventilate the pressure transducer VSP 3000 and/or the vac-
uum system. Make sure that the vacuum connection at the
VSP 3000 is at atmospheric pressure. Allow the pressure
transducer a period of minimum 20 minutes to preheat at this
pressure.
➨
In function ”Configuration” select the menu item ”
Adjust-
ment
”.
☞
The reading is automatically adjusted to ”1000 mbar”. This
value is fix and can not be changed.
➨
Press the selection knob to confirm.
Adjustment under vacuum
An adjustment under vacuum is only possible in the lower
pressure range.
Evacuate the pressure transducer VSP 3000 to a pressure
preferably below 1*10
-3
mbar (e. g. by applying a high vacuum
pump). Allow the pressure transducer a period of minimum 20
minutes to preheat at this pressure.
➨
In function ”Configuration” select the menu item ”
Adjust-
ment
”.
☞
The reading is automatically adjusted to ”zero”. This value
is fix and can not be changed.
➨
Press the selection knob to confirm.
