5.2.2.1 Controls Section
The
Controls
section allows for operational control
of the flowbench as described below.
1
Range Setting:
Clicking the current range
setting will open a popup window that allows the
operator to enter a new flow range setting (1-10).
The SF-1020i has ten (10) flow ranges (see
5-3. SF-1020i Nominal Flow Ranges" on page
17).
2
Servo Mode:
Allows the operator to select
either
pressure
(selected in Figure 5.6) or
flow
.
The SF-1020i is capable of controlling the airflow
to either
test pressure
or
flow rate
. In
pressure
mode, the air pressure is set and the flow rate
measured. In
flow
mode, the airflow is set and the
test pressure measured.
3
Test Pressure Setpoint
:
Clicking the current
test pressure
setpoint
will open a popup
window that allows the operator to enter a new
test pressure
setpoint
. If
Servo Mode
is set
to
Pressure
, t
he operator should verify and if
necessary set the
test pressure
setpoint
in the
unit of measurement
(InH
2
O) prior to testing.
Example:
10
= A test pressure of 10" H
2
0
4
Flow Motor Run:
Clicking the current setting
allows the operator to t
urn the flow motor
ON
(1) or
OFF
(0).
5
Flow Setpoint:
Clicking the current
flow
setpoint
will open a popup window that allows the operator to
enter a new
flow
setpoint
. If
Servo Mode
is set to
Flow
, t
he operator should verify and if necessary set
the
flow
setpoint
in the
unit of measurement
(CFM) prior to testing.
Example:
10
= A flow rate of 10 cfm
6
Ready To Test:
This green indicator will illuminate when the
flow motor is
ON
(1).
7
Auto Zero:
Allows the operator to select if Auto Zero is
ON
(selected in Figure 5.6) or
OFF
. With Auto
Zero
ON
, the flow bench will ignore small changes in test pressure and flow pressure over
time.
8
Logout:
Logs the currently logged in user out and returns them back to the login screen.
