1. Press
key to turn on the meter.
2. The display will show the air velocity reading directly on the air velocity display.
3. The flow type setting is displayed on the flow set up display.
4. Press “FLOW” key to select the desired 2/3V MAX mode, AVG mode or current mode.
If 2/3V MAX mode is chosen, the “2/3V MAX” symbol will be displayed. The meter will
use the maximum air velocity value obtained to determine the 2/3V MAX Air Flow.
If average mode is chosen, the “AVG” symbol will be displayed. The meter use air velocity
average value (the last 30 samples) obtained to determine the Average Air Flow.
If current mode is chosen, no symbol will be displayed. The meter will use the current
air velocity value obtained to determine the Current Air Flow.
5. The display will show the air flow reading directly on the Air Flow Display.
5-5 MAX/MIN/AVG Recording Measurement
1. Press “MX/MN” key to enter the recording mode, the “ REC ” symbol is displayed and
the auto power off function will automatically be cancelled.
2. Pressing “MX/MN” key to scroll the display through the maximum ( REC MAX ),
minimum ( REC MIN), average ( REC AVG ) and current ( REC ) air velocity
readings.
3. Press “ H HOLD” key to pause recording, the “ H ” symbol is displayed, press
“ H HOLD” key again to resume recording.
4. Press “MX/MN” key for 2 seconds to exit this mode.
5-6 Air Velocity Manual Data Memory and Read Mode
TEST ID 0 Memory Mode :
1. Press “Test ID” key to select the “TEST ID 0” memory.
2. Press the “
AUTO MEM” key, to store one set of readings into the memory and
increments the “sample” display by 1, up to the max total memory size of 99 sets, the
“ M ” symbol will also be shown each time to confirm the storage.
3. Press “READ” key to enter READ mode, the display will show “ R ” symbol and the
memory address number. Press
or
key to select the desired memory address
number data for display. Press “READ” key again to exit the READ mode.
5-7 Air Flow Manual Data Memory and Read Mode
Memory Mode, TEST ID 1 ~ 4 only.
1. Press “Test ID” key to select the manual memory mode location. “TEST ID 1 ~ 4”.
2. Press “
AUTO MEM” key to store one set of readings into memory and increment the
“TEST ID sample” display by 1, the “ M ” symbol will also be shown each time to
confirm the storage. The maximum total memory size is 99 Manual sets.
If the flow parameters are change when in the read mode, the TEST ID will
automatically increment.
