Page 15: Operation Mode
www.DataSheet4U.com 7.3 Operation mode 7.3.1 Sensor stabilization time (WARMM-UP) You have to wait for sensor stabilization time because a detector does not act immediately. At this time, the value from 0 to 100 %LEL are indicated for 30 second. (Sensor stabilization time) 1) Alarm output does not brake out. - Page 16 www.DataSheet4U.com After you saturated point, you may set the indicated value to 50 by SPAN VR. Ⅱ. Transmitter (2,3-wire type) 1) After 4 mA is supplied by a current source, you set the zero point by the Zero VR. 2) After 12 mA is supplied by a current source, you set the 50 point by the Span VR. 3) You do not need to calibrate the setting because setting points are calibrated when products are shipped.
