Chapter 2. Safety Instructions
2-1. Purpose of usage
This analyzer is a equipment to measure the gas emission density of an automobile enabling to
diagnose the automobile status and its preventive maintenance so that it can provide a function
to prevent the air pollution in advance.
2-2. Usage condition
(1) No emitted/polluted environment.
(2) Less than 1000m in height and less than 85% in relative humidity.
(3) No direct ray of sunlight, vibration and abrupt temperature change.
(4) Well-ventilated place.
(5) It should be setup at least 25cm from the ground surface.
2-3. Caution and warning
(1) General safety requirement
※
Warning
This item includes some critical contents to prevent safety
accident and product damage so that it needs to be read
through and properly understood for correct usage.
① This analyzer should be manipulated only by the trained personnel who well
understood the usage.
② A spot check or periodical check should be executed in accordance with this manual prior
to a measurement.
③ The probe should be installed in a place where not affected by a wind.
④ If there occurs a unusual case during operation, please stop the operation and contact us
for its inspection and verification.
(2) Warning
① This analyzer is designed for the use of AC110V only or AC220V only. Please verify the
power sources prior to the usage.
② The probe is so hot by emitted gas. Therefore, you need to pay high attention not
to be burned during when you insert or remove.
③ During the analysis, please do not stay long in the place to which the gas is being emitted.
④ The emitted gas normally includes the CO, which may induce a fatal damage to a human
body, so that it must be used only in well-ventilated place .

3-2 Appearance
This manual is explaining mainly HOW TO USE 4GAS analyzer. 5GAS analyzer is just
added with NO sensor on 4GAS analyzer. So, for 5GAS analyzer, use this same
manual. You also can use the same manual for motorcycle which emits high density of
HC. Measuring range of the HC is 0 - 20,000 ppm and display window is specially
custom-made in order to indicate 5 digits segments, and for CO, CO2, O2, the display
window is indicating 4 digit segments as in general.
Other features such as the sequence and a series of procedures including GAS
calibration is same as those for 4GAS analyzer. So, you can use the same manuals as
well.
