Measurement
DT90 data logger enables taking measurements "on request". When configuration is complete, you can check whether
all parameters have been set in compliance with the user's initial assumptions. You can check whether all the connected
sensors operate correctly.
After selecting Instantaneous measurement tab from the main menu, the window from is visible.
Load Data
If data transmission using mobile network fails, or if the user decides not to use wireless transmission, measurement
data might be downloaded using a dedicated USB cable and computer with
DT90 Config
software.
After establishing connection with the logger data download can be triggered. The appearing window allows to select the
location and name, under which the data file is saved. After confirmation the logger starts data transmission. Depending
on memory capacity, transmission might take from several dozens of seconds to even several minutes. Progress in
transmission is shown in a filled up bar.
Get Time
This function will show logger’s current time and time synchronisation status
Clear Log

Firmware Update
Requirements
DT90 configuration software enables updates of DT90 logger's software via USB interface. Before starting software
update ensure that the connection between the computer and the logger is stable. The connection cable needs to be in a
good condition. It is recommended that its length does not exceed
two metres
.
It is not recommended to use an extension cable for USB to update the firmware. Unstable connection resulting from
damaged or too long cable might result in interrupting transmission during software upload. Irreversible blocking of a data
logger's operation might be a result of it. In such case only a
repair at the manufacturer's service centre
is possible to
restore the logger to work. A safe charge level of the internal battery pack is another condition of safe software update.
A safe update is possible if the battery voltage exceeds approximately 3.6V.
Note:
Only a .hex file provided by the manufacturer can be used for update. The manufacturer is not liable if the user uses a file from an
unreliable source.
