readings will respond accordingly. If low or high alarm levels
are exceeded, an alarm indication will appear in the first digit
of the display. An “L” indicates a low alarm while an “H”
indicates a high alarm. If a 4-20mA fault occurs, either a “P”
indicating an open loop, or an “U” indicating 4-20 over-
range will be present. From the Normal Operating Mode, the

Alarm Displays
To enter the Program Mode without opening the enclosure, pass over the embedded reed switch
located under CH1 with the magnetic wand (see Figure 5-4). This will enter you into the non-
intrusive program mode.
In this mode you can check sensor type, zero the unit, calibrate the unit, change the span gas
value, and view sensor span. With the enclosure top removed, Program Mode can be entered
using the “MODE” key. The available functions are listed in 8 Troubleshooting.
