DISPLAy MEANING
t<delay the exposure time is not long enough to calculate a value.
Ofl. overflow, i.e. calculated value is numerically higher than can be displayed.
Auto range out of order At least one of the measuring ranges is out of order.
Zero adjust out of range hardware offset levels may be out of range due to extreme temperatures.
Offset out of range Ionization chamber current fails to reach a stable level when the RaySafe
Solo Ct detector is turned on.
Battery down the battery must be charged before any measurements can be made.
Detector is incompatible the connected detector is not compatible with the RaySafe Solo base unit
version.

What is the difference between R/F high and R/F low, and how do I use them?
R/f low is optimized for low signal levels, typically found during fluoroscopy, behind a phantom. It has a high
sensitivity at the cost of a lower bandwidth (0.1 khz) and should be used at dose rates below approximately 1
mGy/s.
R/f high is optimized for higher signal levels and features a higher bandwidth (2.5 khz). It is typically used
before a phantom, and is required for measuring kVp (as opposed to kV).
What is the difference between DENT high and DENT low, and how do I use them?
dent low is a sensor for low dose rate measurements, normally after a phantom or for applications with high
(> 10 mm Al or equivalent) inherent filtration. It has a high sensitivity at the cost of a lower bandwidth (0.1 khz)
and should be used at dose rates below approximately 1 mGy/s.
dent high is optimized for higher signal levels and features a higher bandwidth (2.5 khz). It is typically used
before a phantom, and is required for measuring kVp (as opposed to kV).
