a）Install the bracket on the measuring unit.
b）Place the conduit of the sampling probe over the smoke extraction inlet of the measuring unit and tighten the screws on the catheter clamp to prevent air leakage at the joint.
c）The measurement signal interface of the measurement unit and the control unit is connected with a measurement signal cable.
d）Connect the power input socket of the measuring unit with a power cable.
e）Plug the power cord into the "power outlet" of the control unit. And pay attention to check whether the instrument is well grounded, and the power socket for the instrument should have a reliable protective ground wire to ensure the safety of the operator and the instrumentNote:If the communication cable between the control unit and the measuring unit is not properly connected, the status bar of the display will appear "".Communication errors”。In this case, the user should check that the measurement signal cable is properly connected.

It displays the model, name, and version number of the instrument, and at the bottom of the graph is the status prompt area, followed by the "remaining time" displayed in the form of a countdown, and the warm-up time is 10 minutes. After the warm-up is over, the instrument will be automatically calibrated and will enter the ".Main menuinterface (as shown in Figure 2).
Note:During warm-up, do not place the sampling probe in the exhaust pipe of the vehicle, but in a clean one.
air, so that the instrument can be properly and automatically calibrated after preheating. If you press the no button during the warm-up, the instrument will terminate the warm-up and enter the working state in advance. However, insufficient warm-up time may cause zero drift and excessive indication error of the instrument.
