Tips and Troubleshooting
Unable to Find the Logger
•
Check for the Bluetooth indicator on the logger. If that is
not present, hold down the Bluetooth button on the device
until the indicator appears (about 2 seconds).
•
Make sure the logger is not connected to another app
(phone).
•
Move the phone closer to the device. The maximum
distance between the phone and the logger should be no
more than 20 feet (6 meters).
•
It is recommended that the phone should have
4 to 5 bars for signal level indicator (blue signal
level indicator) for reliable downloads.
•
If the device has already been added to the
watch list (Devices Home Page) it should appear
there and the signal level bars will turn blue if the
logger is detected. Otherwise…
•
Check the add devices page and tap on the
device to add it to the watch list. Then tap on the
logger in the watch list to connect.
Unable to Connect to the Logger
•
Check the add devices list to see if the device is
appearing there and tap on the device to move it to the
watch list on the devices (home) page. Then tap on the
device in the watch list in order to connect to the logger.
•
If a device is removed from the watch list, either through
sliding left on the watch list or removing the device directly
on the Device main page, it will appear thereafter in the
add devices list. This will reset the downloading indicator
such that all of the data on the device will be downloaded
by the app instead of resuming where it left off reading
previously when the app reconnects.
Problem Downloading the Data
•
If there is no new data available a notice is generated
indicating that there is no new data to be downloaded.
•
Periodically due to interference or marginal proximity to
the logger, a download may not complete fully. Cancel the
download and attempt to download again. The app will
resume the download where it left off.
Anomalies – Alarms, Alerts and Warnings
•
In the device main the Status/Alarms is nominally green
indicating no reported issues. Otherwise the problems are
color coded:
Orange: Warning
Red: Errors (Alarms and/or Alerts)
•
Tap on the entry to show a list of what was discovered.
Within the list tap on a color-coded entry for specific
details and explanations.
Manual Start
•
If the app is connected to the logger when manually
starting the logger then tap on the refresh button on the
main page, after starting the logger, to see the logger’s
updated status.
Power Issues
•
A warning will be generated when a low battery is
detected. It is recommended that the battery be replaced
before attempting to download data.
USB/Bluetooth
•
MT4 will not connect to the logger via the USB until
the Bluetooth is turned off. Press and hold the Bluetooth
button on the logger until the Bluetooth icon disappears
(about 2 seconds).
•
Refer to the MT4 user’s guide for instructions on how to
update the unit firmware.
