Correction factors for different target/filter
combinations are provided in Section 5, Calibration
and Adjustment.
The kVp meter uses two differentially filtered detectors whose ratio of integrated outputs is calibrated over
the range of 24 to 40 kVp. Measurement results are presented on an easy to read 3½ digit Liquid
Crystal Display. Status is indicated by decimal point positioning on the readout. Low battery condition is
indicated by LO BAT displayed on the readout.
