hydrogen concentration higher than the Low Low alarm setting, the
Low Low alarm resets, and the following data screen appears.
1 H2/AIR

Note: Allow approximately 30 minutes for the sensor to reach
temperature equilibrium, to ensure accurate readings
Notice that the display shows the slot number and the input range on
the top line, and the current live value along with the unit type are
displayed in the center of the screen.
Note: The "Slot Number" refers to the location of the applicable
circuitry in the digital controller module. Slot 0 is the main
circuit board, slot 1 holds the XDP circuit board, and slots 2-4
may be used for optional circuit boards.
The XDP software permits the operator to configure the meter for his
specific requirements. To accomplish this, it is necessary to leave the
measurement mode and enter the User Program as follows (see the
