1001..1008 - Arithmetic error during computation
▪
May be a PC memory issue
2000 - Acquisition aborted
▪
Software/hardware issue has prevented the program from running
Another possible error that may arise is one where the software loads, but the buttons on
the toolbar for capturing a measurement appear greyed out, as shown below.
This issue will most likely have arisen from the .ini file not being present in the directory
containing the software, or that the folder has not got the correct security permissions set
(every user will need Read/Write permission for this folder).
To fix this problem, open a Windows File Explorer window, navigate to the C:\ drive, and
where it says
“
Search
”
in the top right corner of the screen, type Acoustic.ini. Next, right-click
on the file, select
‘
Cut
’
or
‘
Copy
’
, and then right-click in the folder containing the software
and select
‘
Paste
’
.
Explanation of how the InstaCal program works
Each time InstaCal is opened, it looks to see what Measurement Computing Company
interfaces it can find. The first one found is designated board 0 and the next board 1 etc. It
records the board type and serial number, and automatically edits a
.ini
file to include this
information.
If you change one rhinomanometer system for another, it will have the same board type, but
it will have a different serial number, which means that the USB will not be recognised and
the driver will not be loaded.
If you run InstaCal again, it will look for Measurement Computing Company interfaces,
realise that the one already recorded is no longer present (by comparing serial numbers) and
offer to remove it. When you answer yes, InstaCal will offer to record the new USB interface
and when you say yes it will edit the
.ini
file to include the new board type and serial
number. If board 0 is free, it will automatically designate it as board 0.
