Note
MFC profiles #1 and #2 are default profiles for working with the
MFC function directly in analog units without an MFC flow range
or units. Profile #1 is 0 to 5 V, profile #2 is 4 to 20 mA. When the
MFC function is active with profile #1 or #2 selected, the MFC
units of measure are always V (profile #1) or mA (profile #2). The
UNIT function selects the flow measurement unit.
3.4.9
[RES]
PURPOSE
To set the resolution of ’s display of the flow through the molbloc and other flow
display and entry values.
PRINCIPLE
The resolution with which the flow measured by is displayed can be adjusted. This
feature can be used to reduce the resolution when lower precision measurements are being
made and additional digits might confuse or distract the operator.
The resolution setting determines the number of digits with which flow is displayed. The desired
resolution is calculated based on the nominal full scale range of the molbloc in the current gas
and flow unit of measure and then rounded to the furthest digit to the right (i.e., resolution of 0.001
% on a 100 sccm molbloc is 0.001 sccm).
Note
The default display resolution setting is 0.001 % of molbloc FS.
The RES setting does not affect the resolution of flow information
transmitted remotely. Remote information always has maximum
resolution of 0.0001 % of molbloc FS.
OPERATION
To access the resolution function press
[RES]
.
Press the
[
←
]
to decrease the resolution and
[
→
]
to increase the resolution. Each press
changes the resolution by a factor of 10. Once the desired resolution is displayed, press
[ENTER]
to set the selected resolution and return to the main run screen.
Note
The resolution setting affects the display of the measured flow as well as
other indications and settings (i.e., quantities shown by the [DISPLAY]
functions).
3.5
[SETUP]
PURPOSE
The
[SETUP]
key accesses a menu of commonly used functions and features that do NOT
have direct function keys. These functions include:
<1molbloc>
To initialize a molbloc when it is connected to and/or to identify the molblocs
currently connected to (see Section 3.5.1).
<2stab>
To change the stability limit that serves as the criterion for the flow
Ready/Not Ready
indication (see Sections 3.5.2 and 3.1.3).
<3adj>
To set an
adder
and
multiplier
to adjust flow readings (see Section 3.5.3).
