The vacuum gauge was adjusted using factory standards,
which are traceable through regular calibration in an ac-
credited laboratory (DAkkS calibration laboratory) to the
German national pressure standard. Depending on the
process and/or accuracy requirements, check the adjust-
ment and readjust if necessary. For readjustment, the de-
vice has to be adjusted both at atmospheric pressure as
well as under vacuum but only if the reference pressures
are known with certainty. In the range between 15 to 525
Torr (20 to 700 mbar) no adjustment is possible;
”---- Torr” is displayed.

NOTICE
Adjustment at atmospheric pressure
An adjustment at atmospheric pressure is only
possible if the pressure is higher than 525 Torr
(700 mbar).
➨
Vent the measurement connection of the connected external gauge
head VSK 3000. Make sure that the pressure transducer is at atmo-
spheric pressure.
➨
In ”Configuration” menu, select program ”Adjustment” at the DCP 3000.
➨
Use the selection knob to adjust the reading to the current atmospheric
pressure.
➨
Press the selection knob to confirm.
760 Torr
Note: To determine the actual atmospheric pressure, use an accurate
barometer or get accurate reading from the weather service, or a nearby
airport or other reliable source (taking into account the difference in alti-
tude between the source and the laboratory).
