Realize the active calibration factor is logged for every data point in a *.dat file. This file is not required to
simply view the calibration factor. It was conceived to troubleshoot problems and watch the calibration
history of the load cell over time.
When viewing the "intcal.log" file, if the “Original K_Cal” value is not the same as the previous
”New K_Cal” value, the last calibration was not activated.
If the “intcal.log”file becomes large, simply delete the file after verifying that there are no pending
issues that this file may be used to resolve.

SYSTEM ZERO LOG FILE
The system zero log file is
"syszero.log"
and is stored in the root directory of FPG Tools. This data file
contains the FPG zero information just prior to activating a new FPG zero. The pressure and temperature
information stored in the file are the same as the values displayed in the
<Tare Values>
screen
(see Section 6.3.3). However, the load cell output value "N", represents the zero offset of the load cell
that was removed by taring. For automated tests, this offset can be used to make corrections on the
FPG pressure.
If the “syszero.log” file becomes large, simply delete the file after verifying that there are no pending
issues that this file may be used to resolve.
9.5
ERROR LOG FILE
The error log file is named
"FPG.err"
and is stored in the root directory of FPG Tools. All remote and
calculation errors encountered by FPG Tools generate a new error line in the file. Each line includes a
date and time stamp along with a specific error message.
DH Instruments technical service may request a copy of this file when troubleshooting problems.
This file is intended to be used as a troubleshooting aid for automated tests. If a test sequence is run
overnight and the power goes out for several minutes; FPG Tools will recover and complete the test,
however, there will be bad data in the data file. This file can track down when the outage occurred and
how long it lasted.
If the "FPG.err" file becomes large, simply delete the file after verifying that there are no pending
issues that this file may be used to resolve.
