
*Note: Use of the No Flow type of device on a Probe will allow the instrument to automatically
switch to the GA workflow when the ID is selected. The user can always use special actions from
the menu to switch workflows between GEM and GA.
Pipe Diameter: The pipe inside diameter (ID) is required for Orifice Plate and Pitot Tube type flow
devices.
Orifice Diameter: The field for orifice bore diameter is available for all Orifice Plate flow devices.
Note: For the instrument to calculate a flow the ratio of orifice size to pipe diameter must be between 0.25
and 0.75.
Pump Run Time: Indicates the duration the instrument's pump will run while sampling for the selected
ID.
Device Information: Allows the user to enter general information for the device. This will display on the
screen of the instrument if the user chooses the © View ID Details option from the ID selection screen on
the instrument.
ID QUESTIONS
There are 5 Question Types that can be selected:

None - No question will be prompted to the user

Alphanumeric - An alphanumeric answer can be entered when taking a reading

Numeric - A numeric only answer can be entered when taking a reading

Multiple Comment selection - Up to 8 comments that may be appropriate for this device ID can be
selected in the ID setup. Then one or all of the comments can be selected when taking a reading.

Single comment selection - Up to 8 comments that may be appropriate for this device ID can be
selected in the ID Setup but only one comment can be selected when taking a reading. Comments
