r/f MeasureMent
for best accuracy, center the selected sensor field (r/f low or r/f high) and position the long axis of the sensor
field perpendicular to the anode-cathode axis of the tube.
1. SENSOR MENU
R/F low sensor for conventional low dose rate measurements lower than 1 mGy/s (7 r/min),
normally after a phantom.
R/F high sensor for conventional high dose rate measurements higher than 1 mGy/s (7 r/min),
normally before a phantom.
press STEP to step between sensors and SELECT to select a sensor.
2. MEASURE MODE
the displayed values are updated after each exposure, or continuously after 4 seconds of fluoroscopy.
