Operation 3. Press the UP/DOWN key repeatedly or hold it until the cur‑ rent atmospheric pressure is displayed, e. g., 1005 mbar. Adjustment range 700–1060 mbar (525–795 Torr) Changing pointer direction with MODE key = decrease value / = increase value 5 Value corresponds to current atmospheric pressure.
Operation 6.2.2 Adjustment to reference pressure For adjustment, the vacuum gauge must be evacuated to a pre‑ IMPORTANT! cisely known reference pressure. > Check the accuracy of the ultimate vacuum with a calibrated reference vacuum gauge. > A faulty reference pressure measurement is transmitted directly to the gauge.
