RKI Instruments Beacon 110 - Manual (Page 38)

34 Beacon 110 Operator’s Manual
When calibration gas is applied to the Beacon 110 during a span (zero for an oxygen
detector) adjustment, the Beacon 110 will freeze the display reading at the highest (lowest
for an oxygen detector) response to the calibration gas. The calibration gas can then be
removed and the Beacon 110 will continue to display this reading and retain it in its
memory until the span (zero for an oxygen detector) adjustment procedure is completed.
Calibration Program Flow
Figure 12 and Figure 13 below illustrate the general flow of the Calibration Program for
the two detector head types. See the next section, “Entering Calibration Mode”, for
instructions to enter Calibration Mode. In general, if a question mark, “?”, is part of the
display text, use the UP/YES or DOWN/NO button to respond. Use the UP/YES and
DOWN/NO buttons to increase or decrease a displayed gas reading when performing a
span (zero for oxygen) operation, and use the ENTER button to accept a displayed value
and continue.
