5 Operation Prosonic Flow 92
36 EHauser
6 Unit of indication
To change the units of flow rate and flow velocity on the MEASURE screen:
Move the cursor to UNIT by pressing the
V
or the
W
key. Press the ENT key and select any unit by
pressing the
V
or the
W
key and confirm by pressing the ENT key again.
7 Instantaneous reading
On the MEASUREMENT screen, instantaneous flow, instantaneous flow velocity, analog output and
analog input can be displayed.
Two of these contents can be arbitrarily allocated to the 1st and 2nd stage. Allocation is accomplished
by selection of UNIT (see “Unit of indication”).
If a flow rate is displayed when the flow is stopped, see Page 72 ZEROPOINT ADJUST and Page 73
LOW FLOW CUT-OFF. If the flow display fluctuates, see Page 72 TIME CONSTANT.
8 Exponent
How to read the exponent display:
x10
0 = 1 time
x10 1 = 10 times
x10 2 = 100 times
Example: 1.200 x10 1 corresponds to 1.2 x 10 = 12
9 Integrated flow rate
Totalizers for upstream and downstream flow (+Totalizer/-Totalizer) are displayed at the 3rd and 4th
stage. Integrated flow rate value is available in the range from 0000000 to 9999999. If the value exceeds
9999999, it is automatically reset to 0000000.
10 Status display of totalizers
STOP: Totalizing off
RUN: Totalizing in progress
To start the action of integration, refer to the TOTALIZER function described on Page 73.
11 Reset
The starting value for integration can be set to 0 or any other numeric value. To reset to the preset starting
value, move the cursor to RESET by pressing the
V
or the
W
key, and then press the ENT key. To reset
to any value other than zero, see Page 73 function PRESET TOTALIZER.
12 Curve display
Some values can be displayed as a curve as in this example SENSOR SIG (sensor upstream wave).
