Symptom Cause of Problem
I pressed the ON key on
MultiLogPRO and it did not turn
on. •
Try charging the battery, it may be
weak.
•
You are using an unsuitable AC/DC
adaptor (see page 5).
•
The internal 3V disk battery is
dead.
MultiLab was unable to connect
to MultiLogPRO. •
MultiLogPRO is turned off.
•
The communication cable is not
connected properly.
•
The communication cable is not
connected to the correct PC COM
Port.
•
There is no available Serial COM
Port.
•
The Logger USB driver was not
installed
I downloaded unexpected data.
• There may be up to 100
experiments stored in the
MultiLogPRO. Performing a
Download means loading one of
them in sequential order. You have
probably loaded an old experiment
accidentally. Try using
Selective
download from MultiLab (see page

While running with an active
trigger, MultiLogPRO does not
complete the data logging.
•
The trigger condition has not been
fulfilled.
•
The trigger condition was fulfilled,
but the time period was too short
(less than 300
μ S).
I see voltage units when
sampling using the microphone.
• The microphone is monitoring the
sound wave shape, which is
displayed in voltage units. The
sound level, measured in decibel
values, is another mathematical
description of the sound amplitude.
