Page 11: Wiring The Oxygen Transmitter To A Controller
CAUTION: Do not route power and transmitter wiring through the same controller conduit hub. The power cable may disrupt the transmission of the transmitter signal to the controller. 65-2322RK Oxygen Transmitter • 11 1.800.544.2843 www.calcert.com sales@calcert.com... - Page 12 12. If shielded cable is used, connect the cable’s drain wire to an available chassis (earth) ground at the controller. RKI controllers typically have a ground stud that can be used to ground the cable’s drain wire. 12 • 65-2322RK Oxygen Transmitter 1.800.544.2843 www.calcert.com...

Page 13: Startup
The procedure below describes applying zero emission air, usually called zero air, using a calibration kit that includes a calibration cup, 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. -
Page 14: Maintenance
Calibrate the oxygen transmitter as described in “Calibration” on page 18 of this manual. See the calibration frequency discussion in “Calibration Frequency” on page 18 to determine if a quarterly calibration schedule fits your needs. 14 • 65-2322RK Oxygen Transmitter 1.800.544.2843 www.calcert.com... -

Page 18: Calibration Frequency
Although there is no particular calibration frequency that is correct for all applications, a calibration frequency of every 3 months is adequate for most oxygen transmitter applications. Unless experience in a particular application dictates otherwise, RKI Instruments, Inc. recommends a calibration frequency of every 3 months for the oxygen transmitter. -

NOTE: If you do not allow the gas reading to increase above the decreasing alarm point, then unwanted alarms may occur. 4. Verify that the controller display reading increases and stabilizes at 20.9% volume. 5. Store the components of the calibration kit in a safe and convenient place. 20 • 65-2322RK Oxygen Transmitter 1.800.544.2843 www.calcert.com sales@calcert.com... -
