MULTI FLOW RATE Mode
MULTI FLOW RATE is very similar to the SINGLE FLOW RATE MODE,
except it adds an additional parameter for the number of locations.
This allows you to take several air flow measurements (i.e.
traverses) and get a total average, for example measuring flow rate
from multiple ducts to get an overall average.
The value of each point is the
average of TRIAL(1) to TRIAL(N).
The value of each location is the
average of POINT(1) to
POINT(M). The value of each
location will be stored in the
memory.
Press to enter the Main Menu.
Use to select “4. FLOW RATE”
and press .
Use to select
“2. MULTI FLOW RATE” and press
.
As the same as the SINGLE mode, set
the following: 1. Sampling Time, 2. No.
Trial, 4. Data Storage, and 5. Duct
Entry No.
Use to select
“3. MEAS./LOC.” and press .
Use to select the number of
MEAS. points (1 to 999) and press .
Then use to select the
number MEAS. locations (1 to 999) and
press .
