*) Default setting
In order to set a suitable vacuum-signal level you should turn the rotary switch (also possible during operation)
located under the protection lid in the upper cover. The display shows the lower vacuum-signal level (S1) and
shortly afterwards the upper vacuum-signal level (S2), and after this it switches once between the selected
levels as a confirmation. After a short while the display returns to showing the actual vacuum level.
CHANGING THE UNITS IN THE DISPLAY
The default setting for the AVM™2 is -kPa. In order to switch to showing the vacuum signal levels in -inHg,
you should press the ES button and keep it depressed for more than 3 seconds. Choose unit by pressing the
ES button again within 3 seconds. The display shows PA for -kPa and HG for -inHg. After a short while the
display returns to showing the actual vacuum level.
