Units Of Measurement - LANDTEC GEM5000 Operating Manual

GEM5000 gas analyzer
Automatically zero instrument
Activates and deactivates the automatic zero feature in the instrument
Low Flow Warning
Specifies the point at which the instrument will "Flow Fail". If the instrument detects that it is not able to
extract the appropriate gas flow for analysis the word "Flow" will flash in the upper left part of the screen
where the pump timer is normally shown. If flow does not increase the pump will automatically be
stopped. Adjusting the setting to "Low" will allow the pump to run with less flow going through the
instrument. This may help avoid flow fail conditions when sampling from high vacuum systems.
Purge Time
Specifies the duration the pump will run when activated by the purge feature of the instrument.

5.7.14 Units of Measurement

The Units of Measurement interface allows users to select whether to operate the instrument in metric or
imperial units. The units for each parameter are displayed on the screen.
WARNING: Units of Measure are as critical as the values of the readings stored. Be certain to verify the
appropriate Units of Measure for your project prior to making a change to this option. Changing the Units
of Measure will NOT convert any existing values stored in the instrument. To avoid confusion, download
any stored readings prior to changing the Units of Measurement.
Clicking on the Set Units button will bring up the Change Units Password box. If you must change the
units of measure please call LANDTEC's Software Support for a password.
