HALLCAL.EXE
The Hallcal.exe program was developed by Lake Shore to allow the interfacing of a customer attached
Hall sensor to a Lake Shore gaussmeter. Because of the many intricacies involved with proper calibration,
the Customer must accept responsibility for the measurement accuracy.
1.3.1
Requirements
•
Lake Shore gaussmeter connected via RS-232 to the computer in the COM1 port. (NOTE: Computer
interface cable must be a NULL MODEM type.)
•
Lake Shore MCBL-6 or MCBL-20 cable assembly.
•
IBM or compatible computer.
•
Hall sensor meeting the sensitivity ranges given below.
•
Calibration or sensitivity constant and serial number of the Hall sensor.
1.3.2
Program Setup and Operation
1. Set the Lake Shore gaussmeter to 300 b
aud. Refer to your User’s Manual on how to set the
gaussmeter to communicate at 300 baud.
2. Insert the disk into the computer and type in the default drive (
A:
or
B:
).
3. Either double click on Hallcal.exe or enter the command
HALLCAL
from the program line. This will
execute the Hallcal.exe program.
4. The program will prompt for the Probe serial number. Any combination of 6 letters or number can be
entered. Press
Enter
when this is accomplished.
5. The program will prompt for the probe type (0 or 1).
Enter “
0
” for Hall sensors with sensitivities between 5.5 and 10.5 mV/kG (at 100 mA current).
Enter “
1
” for Hall sensors with sensitivities between 0.55 and 1.05 mV/kG (at 100 mA current).
6. The program wil
l prompt for the “Calibration Constant.” Enter the magnetic sensitivity in mV/kG at a
control current of 100 mA. Remember to account for the 420
Ω input impedance of the gaussmeter
when calculating the proper load resistor to install.
7. The program will display all the values entered along with designated F keys:
F1
Probe Serial Number
ABC123
F2
Probe Type
0
F3
Calibration Constant
X.XXX
F10
Program Probe
Esc
Exit Program
8. At this time, if any of the parameters need to be changed, just press the appropriate F key and type
in the new value. When everything appears correct, press F10 to program the probe.
9. It takes about 20 s to program the probe. After the probe is programmed, press the
Esc
key to exit
the program.
