Parameters
If the MODE key is actuated and held down while the meter is switched off, the meter will be switched to system mode after 5 sec.
The set parameters are displayed successively with each key depression:

The value set for the given parameter will be displayed if the key is not actuated within 5 sec.
Then the above described alternatives are changed with each key depression.
The meter is switched again to measuring mode after 5 sec. without a key being depressed.
In AUTO-OFF mode (arrow points downwards on the display) the meter is switched off after approx. 20 sec.
Exchanging batteries
The appearance of the battery-symbol in the bottom left hand corner of the display indicates that the battery is exhausted and must be ex-
changed. To ensure measuring accuracy the last measurement should be repeated once again.
A rechargeable battery may be recharged while built in.
Warning
Be care to charge with correct power supply (9 V direct-current)
Calibration
The meter should be calibrated in our measuring laboratory at the latest every 6 months. For calibration a special pumping unit is necessary.

When intermediate value storage is switched on (see 4. Parameters) a maximum of five pressure values below a threshold of 800 mbar which are
maintained unchanged for longer than 3 sec. (within a band of +1.5% of the actual value, but at least +2 mbar) are successively stored. In the
event that a value has been stored then renewed storage is only possible if pressure values are activated outside the band ± 10 mbar of the last
stored value. The stored values can be displayed consecutively by the display.
