Troubleshooting
Typical error messages that may occur during operation are listed below.
Try to solve the problem with the following help list before contacting your distributor.
A) No logger is displayed
First, check if the logger cable is correctly connected to the USB Port
and to the logger. Secondly, uninstall the software and re-install the
complete package (software/USB-driver). Administration rights are
required during the installation process. If the problem still exists there
may be a fault with the logger.
B) Unknown Logger is displayed
The software being used may be an old version, which doesn’t
recognize the new hardware. Check with the local dealer for any
upgrades.
C) Cannot contact logger
If the error message continues to show after checking that the loggers is
connected correctly and appears in the YoyoView software. This could
be due to the logger having a flat or missing battery. Replace the battery
and verify initial function test as follows:
After having inserted the battery the LED on logger front should flash in
all three colours (LED chaser). This shows the logger is operating. Now,
try contacting the logger. If problem still exists there may be a problem
with the logger hardware, contact the local dealer.
D)
Logger stops taking readings after a period logging.
Please check the logger setup for any settings selected for a stop
date/time, change the setup if necessary. Otherwise this could be due to
a flat battery. Check battery voltage in YoyoView (see chapter 4.1) and
possibly replace battery.
E)
Humidity/Temperature readings continuously show -40°C/+120°C .
Humidity/Temperature-Sensor is faulty or the cable has been damaged.
