1. GENERAL
This manual describes the installation, operation, and the maintenance of the zirconia oxygen analyzer con-
verter. Read it carefully before using the converter.
For the detector, flow guide tube and ejector used with
the converter, refer to relevant instruction manuals.
1.1 Direct insertion type zirconia oxygen analyzer
The direct insertion type zirconia oxygen analyzer consists of a direct insertion type zirconia detector (type
ZFK) and converter (type ZKM).
The analyzer intended for the measurement of oxygen concentration in exhaust gas is used for combustion
control.
Caution
Power voltage for the converter must conform to that for the detector to be connected. Don’t use any
power voltage different from the power specifications of the detector. Otherwise it may result in damage
to the detector.
