2.3 KV LOOP
Extended Memory Location E06 contains the calibration factor for kV Loop.
Each number above or below of the indicated in the E06 memory location
increases or decreases respectively the kV gain value.
Value in E06 Memory Location is only related to the Generator
performance (it is not related to the X-ray Tube(s) or another
components installed), so value in this Memory Location is
factory adjusted. Only perform this procedure if the HT Controller
Board and/or HV Transformer have been replaced in the unit.
The k V Gain for kV Loop can be manually calibrated with a Non-Invasive kV
Meter (recommended procedure) or Auto-calibrated with HV Bleeder.
Manual Calibration of E06 Memory Location
1. With the Generator power OFF:
G Set Dip switch 3000SW2-2 on the HT Controller Board in “Off”
position (enables Filament and Rotor Interlocks).
G Set Dip switch 3000SW2-4 on the HT Controller Board in “On”
position (Digital mA Loop Open / Filament Current Constant).
G Remove the link between the banana plug connections on the HV
Transformer. Connect the mAs Meter to the banana plug
connections to measure mA or mAs.
G Place and center a Non-Invasive kVp Meter on the X-ray Tube
output at the required SID (refer to the Non-Invasive kVp Meter
documentation).
2. Enter in c alibration mode by pressing the “Manual Calibration” button on
the GSM Program. Select an available workstation (WS) and press the
“OK” button.
3. Select the E06 Memory Location and read the calibration value by
pressing the “Read” button. Enter the value “200” and store it by pressing
the “Store” button.
