Operation

4.1Startup of Oxygen Analyzer

4.1.1 Preliminary

Before applying power to the instrument, TBE/AI suggests that the electrical wiring installation be checked against the interconnection dia- gram (see Figure 6), especially if the installation has been made by person- nel other than those responsible for startup and operation. In many in- stances, proper attention to this preliminary check will prevent severe damage due to accidental wiring transpositions.

4.1.2Meter Zeroing

Before turning power to the analyzer on, (RANGE switch in any position but OFF), the mechanical zero of the meter should be checked and adjusted, if necessary. The meter indicating pointer should be in precise coincidence with the scale zero mark. Use the mirror to eliminate parallax; adjust the screw on the face of the meter to zero the pointer. Zeroing of the meter is important to achieve maximum accuracy of the meter, and even more important if remote indicating and/or recording equipment are in- volved in the system. An offset zero on the meter will result in a tracking error between the two devices which would be significant if the meter is used to calibrate the analyzer (normal procedure).

CAUTION:

Never attempt to make this adjustment with the power on.
