Configuration windows comprises the following elements: Properties Pane on the right hand side is used to display various setting depending on menu selection. User can define these setting according to requirements. - Page 11 Each channel have might be configured by setting the following fields: Figure 4: Weather Station Sample Program Input Signal source for the channel, selected from the list depending on the device. The drop-down list includes: SDI-12 – digital sensors operating in compliance with SDI-12 standard (see SDI-12 (P14)) Internal analog –...
- Page 12 The number of seconds shown here as xx depends on the sensor connected to the logger and on the so-called Measurement Delay available in Global Sensor Settings tab. The time, at which measurement is recorded in FLASH non-volatile memory is the time of completing a sampling cycle. In special cases, when sensor requires a longer starting time (i.e.

This scaling cannot accept floating point number, thus you will need to use workaround using two points scaling. For example if you need to define 1 pulse as 0.1 mm for precipitation, because you can’t define 0.1 on “a” component thus you can use this method: Figure 7: Scaling to achieve floating point factor Unit... - Page 14 MODBUS RTU In this page user can set serial port setting as well as parameters location within MODBUS sensor including sensor address. Later on after setting up this page user can create channels within Sensors (P10) page. Figure 9: Serial port configuration Figure 10: The first 3 MODBUS entries out of 10 entries There are 9 configuration settings (from A to I) and each of them deals MODBUS block read.
- Page 15 Figure 11: SDI12 Settings Other Settings DT90 loggers enable powering measurement equipment from own power source. Depending on the logger model type the user can choose between: 12V – stabilized 12 V voltage from an integrated inverter with maximum current efficiency at the level of 200 mA (DT90 L) and 100 mA (DT90 N) 5V –...

Page 16: Data Transmission
Data Transmission Data transmission setting control data connection to 4G network, FTP destination as well as transmission interval. Within FTP configuration user will need to provide server name and credential, you can also set the number of retries if the transmission failed. -
Page 17: Setting
Alarm mode may trigger: A change of transmission intervals (settings in Data Transmission tab), however it will not change the sampling interval on that channels. Sending one text message to maximum three destination number. Alarm Configuration This setting will allow user to set alarm threshold from three possible alarm events. The selection is limited to upper or lower threshold exclusively, which mean only one threshold can be selected on every event. -
Page 18: Connect
Connect Page Description Connect menu provides a tool to establish connection to the logger via USB. If DT90 device is powered and has been correctly connected to a computer using an USB cable, the software will automatically recognize the loggers COM port number after clicking Auto Detect button. While Save button will allow you to save the port's setting as well as initiating the connection. -

Page 29: Care And Maintenance
Care and Maintenance Transport DT90 data logger starts measurement after receiving power from a single-use or rechargeable battery (it does not have a power switch). Due to this fact the device should be disconnected from power for transport and storage. This prevents premature discharging and logging non-representative measurements. -
