Problem / Error message
Connection to test voltage
source or PD detector cannot
be established
The system of the PD
detector apparently crashed
(LEDs light up red)
Software is very slow;
delayed response to user
actions
The software is slow to start
and takes up a lot of space
on the hard drive.
When the software is opened
for the first time, no new
measurement job can be
started
"Overflow"
"Processing pipeline limit
reached!"
"Calibration failed"
Cause / Remedy
Restart the affected device
•
Restart notebook and measurement software
•
Check cabling
•
Make sure that the device is supplied with power
•
and, if possible, measure the supply voltage
Briefly disconnect the PD detector from power to initiate
a restart.
The processor is heavily utilized by other processes or
running at reduced clock speed.
Close all other applications
•
Deactivate the virus scanner
•
Deactivate the power-saving mode
•
Large volumes of data may accumulate in the
installation directory due to the amount of measurement
data recorded. This depends on how long and how
intensively the software is used and may also delay
software start-up.
Cleaning measurement data (see page 70)
•
• Defragmenting the database (see page 63)
No devices have been configured (see page 63) in the
software.
Measured data exceeds the input data range.
Increase the measuring range (Q range) in the
software.
The computing power of the computer used is not
sufficient to process the amount of incoming
measurement data.
This problem can be counteracted by decreasing the
maximum number of localizations during VLF sine
wave voltage measurements (see page 63).
The start and / or end reflection could not be
unambiguously identified by the software.
Try again with low bandwidth setting
•
Check the electrical connection of the calibrator and
•
whether it is still switched on
Make sure the cable under test is not earthed /
•
short-circuited
Try to manually position the markers
