3. Installation
This chapter describes how to install the following equipment and how to test the
insulation resistance.
3.1 High-temperature Humidity Analyzer
3.2 ZA8F Flow Setting Unit
3.3 ZR20H Automatic Calibration Unit
3.4 Case Assembly for Calibration-gas Cylinder (E7044KF)
3.5 Insulation Resistance Test
3.1 Installation of High-temperature Humidity Analyzer
3.1.1 Location
The following should be taken into consideration when installing the analyzer:
(1) Easy and safe access to the analyzer for checking and maintenance work.
(2) Ambient temperature of no more than 558 C, and the terminal box should not be
affected by radiant heat.
(3) No corrosive gases.
CAUTION
A natural convection type analyzer (model ZR202G-h-h-h-C), which uses ambient air
as reference gas, requires that the ambient oxygen concentration be constant.
(4) No vibration.
(5) The measured gas satisfies the specifications described in Chapter 2.
(6) No measured gas-pressure fluctuations.
CAUTION
• Be sure to select the installation location where the ambient temperature is between
-208 C and 558 C for the ZR202G Integrated-type High-temperature Humidity Ana-
lyzer.
