Transpector CPM Operating Manual
6.6.2 How to Test for Proper Settings
With zero pressure applied, the display will show 0 pressure (small negative
numbers are acceptable) and the display will be colored red.
NOTE: The following test assumes the pressure unit is psi.
Apply a pressure of slightly greater than 58 psi and the display color should
illuminate in green. Increase the pressure slightly greater than 100 psi and the
display color should illuminate in red. Set pressure to a nominal 80 psi operating
condition and the display color should illuminate green.
In normal operating conditions, the display is red when the pressure is below 58 psi
or above 100 psi.
Interlocks ensure that the system will not be damaged by an air pressure failure
and the CPM will shut itself safely down after ten seconds.
