My device is showing an error:
Error 28
apparently is something related with "filament overvoltage" but how can i fix this? is there any manual with instructions ? RE: Hologic - Lorad M-IV Series
Hello, dear colleagues.
I am trying to calibrate a Loral MIV mammo system. This system has a Varian x-ray tube.
According to section 4.3 ADJUSTMENT-TUBE BIAS VOLTAGE of chapter 3 there is a table showing the Tube Bias values for both filaments for different types of x-ray tubes (Varian and Toshiba). Those values go from 1 to 10.
Doing the adjustment procedure, a 7-segment display on Host Microprocessor shows the Tube Bias Voltage value. I am confuse about it, because the table mentioned before gives 10 values, while I can only get one value, that is 5v. What that is meanHow can I get all those values?
Could somebody clear my confution? Please.
Thanks before hand.

I´m trying to fix a Lorad M IV mammography system.
Every time I make an exposure, error 23 appears. Is it possible that a miscalibration could cause that problem?
Could I use a non-invasive apparatus to calibrate the system?
Any help will be highly appreciate.
Regards. RE: Hologic - Lorad M-IV Series
