5.2 Avoiding Problems
•
Please strictly observe the following:
Always power the H-25C from the proper AC line voltage for its specification. Always set the supply
voltage selector switch to the proper position for the voltage in use.
Transformer damage will result if you mistakenly connect a 100 V range instrument to a 200 V range
power source.
•
Do not let the probe absorb liquid or highly concentrated halogen gas. Doing so will shorten the life
of the sensor and the activated charcoal filter, and may cause malfunction.
To keep dust and other foreign matter from being sucked into the instrument, always attach a probe
when operating the instrument.
•
Use the H-25C only indoors or in an equivalent environment.
When storing the H-25C, select a location where it will not be exposed to corrosive gases or high
humidity.
To obtain the best leak detection performance, keep the following in mind:
•
Ventilate the work area well so that contaminants cannot accumulate in the air.
•
The surface on which you place the H-25C should be nearly horizontal, and should not vibrate.
6. Preparing for Use
Before using the H-25C, you must set various switches according to the detection conditions (gas to be detected,
detection sensitivity, etc.), and make various adjustments (calibration gas secondary pressure, calibration request
interval, etc.) in order to obtain proper operation.
The text that follows shows the basic procedures for preparing to use the H-25C, and the measurement and
calibration procedures. For details, see Sections 2 through 4 of this manual. Note that this manual explains both
how to operate and how to maintain the H 25C. Also, in case of malfunction, this manual explains how to make
those repairs which can be made by a user. You should be sure to read this entire manual once before using the
instrument.
Note: This manual applies to instruments manufactured after September '94.
