ASSEMBLY
This procedure can be used to verify whether the battery packs are performing
adequately.
WARNING... Steps within this procedure produce X-rays. Use appropriate precautions.
1. Select FILM mode and set the technique for 75 kVp and 200 mAs.
2. Make an exposure and verify that an "X-ray Overtime" message is not displayed.
Verify that other technique errors such as "kV Error" and "mA Error" are not
displayed. See kV Generation and mA Generation sections of this manual for
details of these error messages.
OR
With the C-Arm covers removed, make an exposure and verify that the red LED
bargraph located on the Battery Charger PCB indicates 160 to 170 volts.
3. If the bargraph voltage indicates less than 160 Volts, measure across the battery
terminal with a DMM while making an exposure. If the batteries measure less than
160 Volts, weak battery packs or a fault with the Battery Charger PCB may be
indicated.
