User Manual EE680 4 Probe Mounting The EE680 can be mounted on walls, ceilings or inside safety workbenches. Fig. 4 and Fig. 5 show the principal probe mounting alternatives, depending on the probe type. Fig. 4 EE680 mounting on a wall Fig. - Page 10 Remove the sensor protection cap before commissioning. PLEASE NOTE For best measuring accuracy, the sensing element of the EE680 must be aligned exactly in the direction of the laminar flow in which factory adjustment took place. The factory adjustment direction is indicated by an arrow symbol on the sensor tip. The arrow on the sensor probe shall be pointing exactly in the direction of the laminar air flow.
