Figure 6.1 Startup
(1) Checking wiring and piping, when using the sampling unit
Ensure that wiring is made correctly in accordance with the procedures described in
Chapter 4. Piping is only required when using a sampling unit. Ensure that piping is
installed properly so that it is free from gas leakage.
(2) Checking gas flow rate, when using the sampling unit
Turn on the power switch of the sampling unit. Adjusting the gas flow rate should be
performed with the sensor connected to the sampling unit. While opening the flow
regulating valve of the flowmeter completely, adjust the front needle valve until the
flowmeter reads approximately 500
(3) Applying power to the converter
Ensure that the power supply voltage conforms to the specification of the converter
before applying power to the converter (see Section 1.1 (19)). Turn on power to the
converter. Measurement is not available for the initial 10 minutes since it takes that
time for the sensor to reach the required operating temperature. The initial converter
parameters are the default settings. If necessary, change the parameters to meet your
application requirements, referring to Sections 6.2 and 6.3.
Briefly after the converter is energized, it shows values at random on the display for
about 5 seconds and then switches to measurement mode to indicate approximate values
of the oxygen concentration at sampling point. At this stage, the readings are invalid
since the sensor temperature has not reached the required operating temperature.
