6) To increase or decrease the kVp, Press kV up or down. Each
activation of the button increases or decreases the kVp
approximately 05. kVp. The number displayed in the mAs window
represents a digital code for kVp reference and is increased or
decreased by one with each activation of the kV switches. Adjust
the kVp until the Actual kVp is within specifications.
7) When the calibration of kVp is completed for the 40 kVp range,
press the “RESET” to move to the adjustment.
8) Repeat steps 1 – 7 for the 50, 60 and 70 kVp ranges. The Display
will show 04,05,06,07 for the Preheat adjustments and 40,50,60,70
for the kVp adjustments.
9) Press RESET until the kVp Display shows ‘60’.
10) Reset the MAS Meter to Zero.
11) Make an Exposure and measure the actual mAs.
12) Observe the reading on the MAS meter. The reading should be
1.0mAs +/- 5%. If adjustment is required, adjust R102 on the
Control board assembly. Inspect squareness of wave-shape and
repeat steps b - h above if necessary.
13) When calibration is complete Recycle power to the unit to return to
