Data Files are not being
stored to the right directory. Data Files are stored under the Data
File name and the directory path
specified. You may not be looking in
the correct directory path. Familiarize yourself with the Data
File naming and storing protocol.
Also consider that the
COMPASS
main program and the COMPASS
Report Editor may be specifying
two different paths. 18.3, 11.8,
16.3.4.4.
The front panel of my DUT
displays more resolution than
the main run screen of
COMPASS .
The output resolution selection in the
DUT Definition is less than the actual
DUT device resolution. Use the DUT Definition Editor to
change the <Output Resolution>
field of the DUT to get the desired
output resolution. 8.5.4.
When running COMPASS ,
the front panel of the molbox
only displays mass flow in
units like kg/sec, mg/sec, or
mol/sec.
COMPASS resets the molbox to a
known state which removes any user
setups of units, gas, K-factor, etc. The
front panel options for the top row
display are: mg/s (Default), kg/s, mol/s,
slm @ 0.00C, sccm @ 0.00C, scfh @
0.00C, and scfm @ 0.00C.
Using the [AVERAGE] or
[DISPLAY] key on the
molbox1/molbox RFM front panel,
you may select the mass or volume
(actual) flow units that you would
like displayed on the second
(bottom) line of the molbox display.
(The units of this display will not
change when you change units
within
COMPASS. ) Refer to the
molbox/molbox Operation and
Maintenance Manual,
[Display] ,
<5unit> Section for details.
