Ion Chambers And Dose Diodes - Radcal Accu Series User Manual

"Dose diode fail"
These errors arise from problems with the DDX10 kV dose diode. If connecting a working diode clears
the error condition, the messages become "kV - try again" and "Error cleared", and a new measurement
can be performed.
"No kV diode" The diode was not connected to the Accu-KV sensor and a dose-related
measurement is specified.
"Wrong kV diode" The wrong diode is connected to the Accu-kV sensor.
"EPROM error" The diode EPROM did not respond properly.
"System error"
The top line of the display shows "System error", with the bottom line showing one of several messages.
Exits to the main menu after displaying the message for two seconds. Contact Radcal if it persists.

Ion chambers and dose diodes

These messages arise when measuring dose and dose rate using ion chambers or the DDX6 dose
diodes.
Starting a measurement:
"Dose sync fail" Press SELECT to retry.
While measuring zero:
"Zero too small"
"Zero too small"
"Zero unstable"
While measuring dose or dose rate:
"?" In the upper left corner. Indicates the sensor is operating above its specified
maximum rate.
While measuring dose-rate
Automatic retry after 3 s.
"Input negative" The converter output reached zero.
"Conv overload" The input current overloaded the converter.
While measuring dose
Displayed until user presses SELECT, then function exits.
"Input negative" The sensor signal was negative..
"Conv overload" The sensor signal exceeded full-scale.
"Dose overflow" The total dose was too large.
"Time overflow" The dose-accumulation time was too large.
Press SELECT to continue. Measurements near minimum dose rate for the
selected sensor may be inaccurate.
