If you initiate the change span
option, the status bit will start to
flash and the span value can
now be changed. The current span
value is displayed on the top line of
the LED display. Use the “↑” and “↓”
keys to change the span value.
When the desired value is reached,
press the “ ” key to save changes.
Pressing the “Mode” key or letting
the timer count down to zero without
saving the new value, will take you
back into the Programming Mode.
NOTE: If the “ ” key is not pressed,
the new span value will not be
saved.
NOTE: Span Gas Concentration for
combustibles can be set from 0% to
100%LEL. For the sake of resolution,
we suggest that Span Gas
Concentration should be set above
20% LEL.
