3. Calibrator
The ADT273Ex calibrator can be used to calibrate and measure pressure, as shown in Figure 5. Channel 1 at the top
of the screen is mainly used for electrical signal measurement. It has several types of signals to be selected. Channel 2
at the bottom of the screen is mainly used for pressure measure functions, which has up to 4 pressure channels.
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 this icon to pop up a menu for switching the signal
type. 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 zero the current channel. If the signal type selected in the channel has multiple values for display
(for example, after enabling scaling, it will show the scaled value and initial value simultaneously), the channel will also
display these signal values below the main signal value.
