                        CALPRN Operation
                          04/10/97 -med

The CALPRN.EXE program will read the current calibration table in 
the audiometer and print the results on a printer attached to 
LPT1. CALPRN32.EXE is the Windows 95/NT version of the program. 

To use CALPRN, enter the command "CALPRN 1" or "CALPRN 2" 
depending on whether you are using COM1 or COM2 to communicate 
with the audiometer. For MSDOS it is assumed that you have 
loaded FRYERS.COM before running CALPRN so that it can 
communication with the audiometer. For Windows 95/NT, it is 
presumed that you have the FRYERS32.DLL file loaded in the 
Windows directory so that the program can find it.


The three values returned are:

1. The calibration table Index which is the offset into the 
table at which the calibration value is is located. 

2. The calibration table Value. This is the actual value in the 
calibration table which is in 0.5dB increments.

3. The calibration Offset. This is the offset in dB that is added 
to the internal signal level to obtain the resulting HL SPL level 
that the instrument is calibrated to.
