1. Safety guideline
1-1. Purpose to use
KS 00-4G measures the concentration of automobile exhaust gas to diagnose and maintain the
condition of the vehicle. .
1- . Terms of use
① Use the rated voltage.
② An altitude of less than 1000m and a humidity of less than 85%.
③ Install in a place where there is no direct sunlight, vibration, or sudden temperature change.
④ Install it in a well-ventilated place.
⑤ Install at least 5cm above the ground.
*Notice
If anything unusual occurs, please stop using it immediately and contact the place
of purchase or headquarters for inspection.
Waring
① Please check power before using.
② When probe in and out watch out for burns..
③ Don’t stay longer when the exhaust gas is generated.
* As the exhaust gas contains carbon onoxide (CO) and nitrogen oxide (NOx) that cause fatal
da age to the hu an body, use it in a ventilable place at all ti es.

3. Installation and precautions
3-1. Installation
① Insert one end of the probe hose into the measurement probe and the other end into the analyzer
GAS INLET.
*The exhaust of a car can pulse, especially at low RPM, drawing air in causing bad readings ensure the
flexible probe is fully inserted.
② Place the power switch off, connect the one-touch fitting to the analyzer Inlet and Outlet, and
then connect the probe to the fitting on the Inlet side. After that, connect the power cable to the
power socket behind the analyzer.
*Notice
Please check the probe and filters connection status

① Ready Mode: It refers to a state in which the
power is [ON] but the suction pump is [OFF]
when the measurement is not performed for
a long time.
* KS 00-4G automatically turns off the pump
after 30 minutes to maintain the standby
state.
② After 10 minutes from the ready state, it
automatically changes to STAND-BY mode.
③ Press any button in STAND-BY mode to return to standby again with zero. (STAND-BY mode is not
displayed.)

③ After measuring it, remove the probe from the exhaust port. press PURGE key Clean inside with
fresh air for value reduce to “o”.
④ When the measured value is "0" press ESC key stay on ready mode.
4-5. Leak test
To ensure the gas sampling system is sealed correctly and
not letting in air, the analyzer will perform a leak check.
This requires the user to block the probe inlet and perform the test.
① End of the probe put the cap on.

5- . HC Test
During vehicle exhaust gas measurement, the level of contamination is indicated by measuring the
sample collection probe line and the hydrocarbon (HC) component accumulated inside the analyzer.
① In ready mode press MENU key move on “ HC TEST ”.
② Press ENTER key, start ZERO function.
③ ZERO is complete, start HC % vol test.

order.
① The primary and secondary valves of the standard gas cylinder must be turned clockwise (closed)
and left the cut-off state.
② Release the gas injection pressure control valve counterclockwise to place the pressure-free and
open the primary valve of the standard gas cylinder counterclockwise. At this time, the remaining
gas in the tank is displayed on the primary gauge.
③ Turn the gas injection pressure control valve clockwise to adjust the secondary gauge pressure to
3kgf/cm².
④ Connect the drain hose to the outlet and water outlet nipple.
❖ The standard gas contains toxic ingredients. To prevent direct inhale make sure to prepare for
emissions in the exhaust analyzer outlet and calibrate in a well-ventilated place.
