3. Data logger
The ADT260Ex can be used for measuring and recording many signal types, including the signal of the internal
pressure module, external pressure module A and B, differential pressure module, barometric pressure, 2-wire RTD and
electrical signal measurement, totally 8 measurement features available. The electrical signal measurement supports
voltage, current, switch, pulse, and frequency. On the main page, there can be up to 6 measuring items display at the
same time.
On the middle of the channel there is the current measured signal of this channel. The icon of the signal type and the
corresponding range information is displayed on the upper left; Click the icon in the upper right corner to set the
current channel in the pop-up menu; Click the icon in the lower right corner to perform the zero on the current
channel. If the signal type selected in the channel has multiple values for display (for example, after enabling the scaling,
it shows concurrently the scaled value and initial value), the channel will also display these signal values below the main
signal value. In case of too many channels displayed on the main page, the device will automatically simplify the content
to fit the screen.

3.1 Pressure Measurement
The device can measure the pressure by internal pressure module, external pressure module A/B, differential
pressure, and barometer. The external pressure A and B are only available when the external pressure module is
connected. The differential pressure function is available when it is enabled in the “Pressure Delta ” APP and both the
23
Page 31
two modules are online. Select the proper module in the Channel settings to measure the pressure. Click the pressure
unit above the pressure measurement value to switch the pressure unit in the pop-up unit selection interface.
Click the menu icon in the pressure measurement channel and click the "Settings" menu in the pop-up menu to set
the pressure type, resolution, stability, tare, and other functions of the current pressure measurement channel.
