Calibration Program Flow
Figure 10 below illustrates the general flow of the Calibration Program for a direct connect
detector. See the next section, “Preparing for Calibration”, 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.
Figure 10: Direct Connect Detector Head
This section describes how to calibrate the H
2
S detector. It includes procedures to prepare for
calibration, set the zero reading, set the response reading, and return to normal operation. It
describes calibration using a calibration kit that includes a calibration cup/splash guard, calibration
gas, sample tubing, and a fixed flow regulator with an on/off knob. RKI Instruments, Inc.
recommends using a 0.5 LPM (liters per minute) fixed flow regulator.
Preparing for Calibration
WARNING: The Beacon 110 Rig Monitor is not an active gas monitoring device during the
calibration procedure. The 4-20 mA output signal will “freeze” at 3.5 mA and
all relays will remain in their non-alarm state while the Rig Monitor is in
Calibration Mode. The 4 - 20 mA output signal will not indicate current
readings and the relays will not resume operating normally until the Rig
Monitor is in normal operation again.
