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.

Chapter 4. Circuits of KEG-500
4-1 Measuring principal
This analyzer is configured to perform a measurement by applying Non Dispersive Infra-Red
(NDIR) method for analyzing CO, HC, and CO2, and electrochemical method for analyzing O2
and NOx. In the NDIR analyzing method, a flashing ramp which flashes the infrared rays is
attached at the one end of the sample cell and at the other end a detecting sensor is attached
so that it can detect the component of a gas and then calculate the gas density.
<NDIR method diagram>
The electrochemical method measures the gas density by using the quantity of electron which
produced in the time of oxidation and reducing reaction of the gas.

Chapter 5. Installation Methods and Notes
5-1 Installation
5-1-1 Fit end of the probe hose into the measuring probe and the other end of the hose into the
gas inlet in the rear of the analyzer. If the fitting condition is not good and the air comes
into flow from outside, it may yield an incorrect measured value.
Therefore, please carefully verify the fitting condition before use.
5-1-2 Turn off the power switch and then connect the power cable to the power socket located
in the rear of the analyzer
※
Warning
This analyzer supports AC110V only or AC220V only.
(Please confirm the power source to use.)
19/63
5-1-3 Verify the fitting conditions of measuring probe filter and various filters located in the rear
of the analyzer.
5-1-4 Verify again the connection status of the analyzer and then turn on the power switch.
5-1-5 Connect the ground cable to GROUND on the rear of the analyzer.
20/63
5-2 Notes
▶ This analyzer is operated with AC110V only or AC220V only. Please verify the power source
before use. (Note that you can not change power source which is fixed upon supplying this
analyzer.)
▶ The following factors should be considered to properly locate the analyzer body:
━ To be setup in a place of no direct light rays, humidity, vibration and abrupt temperature
change.
━ To be setup in a indoor place where no emitted gas inflows.
━ To be setup in a height higher than 25cm from the ground.
▶ The analyzer should not be moved during the operation. It may cause an
incorrectness in the measured value.
▶ The probe should be located in a place where not affected by the wind.
▶ The probe may be so hot during the operation so that it should be carefully handled not to be
burned in insertion or removal.
▶ It needs to be noted that you should not stay in the gas emitting place during the operation.
▶ The analyzer should be used in a well-ventilated place only because the emitting gas
contains the CO and it can cause a fatal damage to a human body.
▶ This analyzer is Type-approved in accordance with the related government laws so that it is
extremely prohibited to disassemble, change, or rebuild the analyzer and also if you
disassemble the NDIR Module, you may not be guaranteed for the repair.
▶ NDIR module is the core part of the analyzer. Disassembly or assembly work is
possible only by the manufacturer's technician. In any circumstance, you or anyone
else should not attempt to disassemble it. If disassembled or re-assembled, proper
A/S is not going to be possible.
