Messages are displayed and a beep sounds when the Accu-Pro™ is unable to perform a measurement.
Pressing SELECT generally proceeds. Pressing UP or DN exits to the main menu.
Self-test
"Battery LOW"
Replace or recharge battery
"Analog volt fail"
Precision voltages are out of tolerance. Measurement accuracy is questionable.
"Logic volt fail"
Logic supply voltage is out of tolerance.
May shutdown or operate erratically.
"No converter"
No dose converter connected.
Proceeds after 3 seconds.
"No dose sensor"
Press SELECT to proceed.
"EPROM error"
Press SELECT to proceed.
"Temp Error 1,2"
Unable to read temperature sensor.
Temp Error 3
Temperature out of range.
"No kV sensor"
Proceeds after 3 s or SELECT.
"Std 22 deg C"
Standard temperature was selected.
"Std 101.3 kPa"
Standard pressure was selected.
"Bias failed"
Bias voltage is out of tolerance. Measurements may be in error.
Accu-kV
These messages result from operations involving the Accu-kV sensor. They are displayed for at least two
seconds. The underlined header in the following is the first line of the message.
"Exposure Error"
These errors arise from problems with the x-ray signal.
After two seconds, the messages become "kV - try again" and "Error cleared", and a new measurement
can be performed.
"Too narrow 1,2,3"
Waveform was too narrow.
"Too weak 1,2"
Intensity was too low.
"Too strong"
High intensity caused saturation.
"kV too small"
Measured kV was too small.
0.00 kV
Measured kV too large. Allows dose outputs.
"KV - wait"
These arise form problems that often clear themselves. If the error condition clears, the messages
become "kV - try again" and "Error cleared", and a new measurement can be performed.
W
Accu-kV zero level is unstable.
"Bad kV zero"
Zero level too small.
"Measure abort"
Processing was interrupted.
"Bad W/Ag kV"
Measured kV is in bad-accuracy range for W/Ag correction.
"kV failure"
These arise from a faulty or missing Accu-kV sensor
If connecting a working Accu-kV sensor clears the error condition, the messages become "kV - try again"
and "Error cleared", and a new measurement can be performed.
"ADC error"
Analog-to-digital converter problem. May be an Accu-Pro™ fault.
"EPROM error"
The sensor EPROM did not respond properly.
"No sensor"
EPROM not found or zero level too large.
"Zero failed"
Zero didn't stabilize within 2 minutes.
Unstable zero values cause "W" to appear in the lower-left corner of the display.
