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.

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
