Language
The standard information on the 2020ComboPRO display screen is presented in
English. The languages of Spanish, French, German, or Italian can be added to
the English information as an option (contact INFICON for details). Only one
additional language can be installed on the 2020ComboPRO at one time. For units
with an additional language installed, select the Language from the MENU and the
two languages will appear as a list. Using the center soft key, highlight the desired
language and use the SELECT soft key to set the language.
Units
In TVOC mode, the 2020ComboPRO can display readings in three units of measure:
PPM (parts per million), PPB (parts per billion) or mg/M
3 (milligrams per cubic
meter). On selecting Units from the MENU, the three choices will appear as a list.
Using the center soft key, highlight the desired Units of Measure and use the
SELECT soft key to set the choice. In GAS mode, the 2020ComboPRO can display
readings of PPM and PPB.
NOTE: To utilize the mg/M
3
unit of measure, the instrument must be configured and
operated with a compound chosen from the 2020ComboPRO’s Preset RF library
because a molecular weight value is needed for the mg/M
3
calculation. If you wish
to use the mg/M
3
unit of measure while doing TVOC work, you should use a memory
slot with Isobutylene selected from the Preset RF library. Refer to Section:
Response Factors and Memory Slots for further information.
Sample Collection Mode
The 2020ComboPRO can be used to collect samples for further analysis at another
location with another instrument (e.g., back at a laboratory using a GC). Sample
