According to the present invention, a test system 1 that tests a mobile body such as a vehicle, a vessel, and a plane, or an instrument used in the mobile body as an object, and is operable by switching among different operational modes, can accumulate an operating period of a component much more accurately than conventional system, and includes an accumulated operating-time calculating unit 46 for accumulating the operating time of the component, and the accumulated operating-time calculating unit 46 accumulates the operating time of the component only in the predetermined operational mode.

Test system

The exhaust gas analysis system urges a user to conduct a purge in an exhaust gas flow line by not only informing the user of the timing that the purge is necessary from the exhaust gas analysis system but also making it easy for the user to recognize the information. The exhaust gas analysis system comprises an exhaust gas flow line (L) where an exhaust gas flows, a measurement devicethat is arranged in the exhaust gas flow line (L) and that includes a pollutant component meter to measure a pollutant component to be a cause of pollutant of the exhaust gas flow line, and a display control devicethat compares a measurement signal value obtained by the pollutant component meter or its arithmetic value with a predetermined pollutant tolerance and that displays a warning window on a displayin case that the measurement signal value or the arithmetic value exceeds the predetermined pollutant component tolerance.

Exhaust gas analysis system and program for this system

An exhaust gas measurement device includes a pressure regulator for keeping a pressure of sample gas in a sensor flow line or a bypass flow line to be a set pressure value, a flow rate sensor provided on the bypass flow line for measuring a flow rate of the sample gas flowing through the bypass flow line, and an attention attracting part for displaying that the flow rate of the sample gas is reduced in the case where the flow rate measurement value measured by the flow rate sensor becomes equal to or smaller than an attention attracting flow rate value larger than a pressure controlling limit flow rate value by a predetermined value, the pressure controlling limit flow rate value being a lower limit flow rate value that is pressure-controllable by the pressure regulator.

Exhaust gas measurement device and recording medium having program for exhaust gas measurement device recorded thereon

The present invention is intended to be able to restore a setting of an exhaust gas analyzing device to an initial setting at the time of product shipment or the latest maintenance setting performed prior to the corresponding maintenance in the maintenance of the exhaust gas analyzing device. The present invention includes a setting data storage part () storing initial setting data indicating initial setting information of each part constituting an exhaust gas analyzing device () in a state of product shipment and the latest maintenance setting data indicating the latest maintenance setting information of each part constituting the exhaust gas analyzing device () in the latest maintenance.
