When the device is powered, it enters the measurement
monitoring view. The following measurements may be
viewed from the display. The Table 5 identify the default

If the unit selection is altered from the FieldCare software to
US units, the pressure default unit will automatically be
changed to psi and temperature unit to Fahrenheit.

start scrolling on the display. This enables the user to view
all the measurements through the window of the main
cover.
