When wiring is complete, re-assemble the EX-5100 . Use caution when installing the overlay so as not to damage the magnetic
switches. With the area declassified, apply power to the instrument. Allow the sensor transmitter to stabilize for 1 hour and
then enter the maintenance menu.
C AUTION : Area must be declassified during this procedure.
To enter the maintenance menu hold the magnet over the M ENU switch for 2 to 4 seconds
The chart below indicates the maintenance menu sequence see Figure 5 for a detailed maintenance menu flow chart.
Example of Display Function
Normal Display Mode
Measurement of target gas
Hold the magnet over the M ENU switch for 2 – 4 seconds to enter the Maintenance Menu
The Power/Fault LED will flash Green – Red to indicate the EX-5100 is in Maintenance Mode
To exit the maintenance Menu and return to the Normal Display Mode:
If intended function Tap the magnet over
S ELECT switch
Tap the magnet over the M ENU switch to advance to the Zero procedure
For adjusting Zero:
If intended function Tap the magnet over
S ELECT switch
Tap the S ELECT switch once with the magnet, the display will alternate between [PV: 0] and [Zero]
At this point, tap the M ENU switch once with the magnet. The display should now alternate between [Zero] and
[In 300] (+ or – 30). If not then, use POT 2, to adjust to 300(+ or – 30).
N OTE : The EX-5100 will automatically reset the zero point based on a stable signal if [Span] appears before you get the 300 set
then re-enter the zero cal again, to start the clock over.
Once the zero is set, you will see [Span] on the display. Tap the menu until [E XIT ] is displayed, then tap select once to put the
instrument in the normal operation mode.
