Operation 17
When measuring Flow as the Primary measurement, the parameters
can be quickly changed by pressing the

or

key while on the
main measurement screen:
Make adjustments with the

or

arrow keys and press to
accept, or enter the Select Duct or Select Kfactor menu to choose a
different pre-programmed flow value or dimension.
The Horn numbers are the models of the horns. For example, 100
refers to a horn model number AM 100. Only horns with Model
numbers as follows can be used with this function: AM 100, AM 300,
AM 600 and AM 1200. If a horn model number is chosen, the
instrument will return to measuring mode and use a preprogrammed
curve to calculate flow rate from velocity when using a
thermoanemometer probe.
The Air cone selection applies to the Model 995 Rotating Vane
Anemometer and the Air Cone kit p/n AFL72852201 which are used
to take flow measurements on small outlets.
