10. Reconnect the wiring that connects the controller and oxygen transmitter to the
amplifier’s interconnect terminal strip as shown in Table 4 below and Figure 3 on
page 6 of this manual.
11. Reconnect the detector leads to the amplifier’s detector terminal strip as shown in
Table 5 below and Figure 3 on page 6 of this manual.
12. Turn on power to the controller.
13. Turn on the controller.
14. Calibrate the oxygen transmitter as described in “Calibration” on page 12 of this
manual.
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.
If an application is not very demanding, for example detection in a clean, temperature
controlled environment, and calibration adjustments are minimal at calibration, then a
calibration frequency of every 6 months is adequate.
If the application is very demanding, for example if the environment is not well
controlled, then more frequent calibration than every 3 months may be necessary.
