Dynalyzer – High Voltage Unit
OPERATION MANUAL
31
Wait until the selected cell turns green before making an exposure. Too early may yield errors.
Once an exposure is made, data is collected and processed, values displayed and listed, the
graph will display kV and mA waveforms, and the cell below is selected for the next exposure.
While the active cell is green, Esc is used to exit the measurement loop. Pressing it while the
program is processing an exposure may yield errors or incomplete data.
The program can be restarted using either the button or key combination, picking up where it left
off. This is useful in times where breaks between sets of exposures are required such as changing
filtration. If a selected cell is already populated with data, the previous data will be overwritten. This
is useful when an exposure was made erroneously or was unnecessary. Alternatively, entries can
be manually deleted or moved.
Data
After the exposures are made, the sheet can be saved as is or the values can be copied to another
sheet. Only the last waveform is saved with the worksheet. To save additional waveforms, use
‘Save As..’ between measurements.
Hotkeys
•
Ctrl+Shift+R:
(R)un - Starts the measurement process
•
Esc:
Stops the measurement routine
•
Ctrl+Shift+C:
(C)lear - Clears the digitizer’s USB connection, and causes recognition
of sensor or parameter changes.
•
Ctrl+Shift+U
: (U)pdate - Checks for software updates.
Troubleshooting
Common Error Messages:
Cannot find AccuGoldExcelMacro.xls
:
The macros did not load. Ensure that the security settings are set to ‘Enable Macros’.
Driver failed to open
Windows did not load the driver, probably because the digitizer is not connected. Check
connections, cable, and USB port.
A relevant zero value is out of range
-
The zero value that is measured is outside of its specified limits. Check zero offset of
Dynalyzer mA and A+C BNC out.
-
Generator noise from making or starting an exposure while the measurement loop is initializing
could give this error, wait a few moments for the generator outputs to stabilize before restarting
measurement.
The mAs probe was not connected
or
The connected mAs probe failed to respond
-
Verify connections between the mAs port and digitizer.
Exposures not triggering
-
Verify connections between the digitizer and Dynalyzer.
-
Check Dynalyzer BNC output with oscilloscope.
No mA readings
-
Verify connections between the digitizer and Dynalyzer.
Selected cell was not allowed
-
A cell in any row within the measurement list area under Column D needs to be selected.
Insufficient kV signal
The width of the waveform is too small. Increase the width of the exposure pulse. Triggering
from a brief noise transient can also cause this error.
