3. Calibrator
ADT227 calibrator can be used to calibrate pressure, loop, temperature and flow equipment. The two channels can
be displayed in one page. The channel 1 at the top of the screen is used for electrical signal measurement, HART,
temperature signal measurement and external pressure module measurement. The channel 2 at the bottom of the screen
is used for electrical and temperature signal output, external pressure module measurement. Both two functions support a
variety of electrical signal types.
The measured or output signal value is displayed in the middle of the 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, when measuring the TC temperature signal, in addition to the temperature value, there are also the original
millivolt signal value and the cold junction temperature value), the channel will also display these signal values below the
main signal value.
