Hi
I can't find the GussMeter 475 softwere "HallCal.exe" in the Lakeshore Website, Can someone find it for me?
Thanks !

Hi, what are you hoping to do with the HallCal software? This software was used for older gaussmeters and I don't think is needed for the 475. If you are trying to connect a discrete Hall sensor to a HMCBL cable for use with a 475, read section 5.2 of the manual to see how to program it using the 475. If this solves your problem, could you please let me know? Also, what did you read that pointed you towards the HALLCAL.EXE software? Thanks! |

I want to import the data of Hall Sensor to the 475, and I read from this following page that tell me to use the HallCal softeare. www.lakeshore.com/products/Hall-Magnetic-Sensors/Pages/More.aspxAnd is there a new software or method to import the data of hall Sensor to the 475 ? Thanks! |

OK, thanks! If you look at that page, it says that the 475 does not use the Hallcal.exe software:
Please have a look at section 5.2 of the manual to see how to program a HMCBL cable using the 475. When using a separate sensor like you have, the only things to enter are the sensor excitation (100 mA for InAs sensors) and a single sensitivity value. Hope this helps. Let me know.

Yes, you are right! Thanks! I misunderstood the information of websiet, and I got the right information from the manual. Thank you again! |

No problem. We made changes to our website too, so hopefully this won't be so confusing for the next person viewing that page. Best of luck with your field measurements!

But I have a Hall Sensor HGCA-3020, and I want to connect the sensor to 475. Should I have to using the cable containing EEPROM providing by Lakeshore ? Can I use a general cable without EEPROM to connect them ? |

Hello Jianxin,
It is possible to connect the hall sensor directly to the Model 475 input without using a HMCBL cable, however, the Model 475 Gaussmeter will revert to a resistance measurement requiring you to manually calculate the voltage and then interpolate the field from the calibration data you have.
If you do use the HMCBL cable, you can enter the single point nominal sensitivity value provided with the calibration data you received and the Gaussmeter will calculate and display the calculated field value.
Finally, there is no way to enter the full calibration data table for the HGCA sensor into the Gaussmeter. To use the complete calibration data supplied with the sensor requires you to manually calculate the field between the data points using a separate current source and volt meter or calculating the voltage from the resistance read by the Gaussmeter without a HMCBL cable |

I can record the data using Laview VIs and calculate the field automatically. But is it available in the DC, RMS or Peak mode? I may detect an AC field. Thank you and your excellent products. |

I checked with our design engineer and he informed me that when you power on the Model 475 with the hall sensor connected directly it will display an Invalid Probe error. If you press enter, it will bring you to a screen to enter the nominal sensitivity and the Gaussmeter will then display a field and not resistance. You will need to enter the sensitivity every time you power cycle the Gaussmeter. If you press enter without entering the sensitivity, it will display in resistance.
He also confirmed that this does work in all measurement modes, DC, AC and RMS |
