Note? This instrument is a high-precision testing equipment with a built-in professional precision (NDIR) sensor. Long-distance transportation and express delivery operations may cause the internal light source to shift and lead to errors in the measurement values. If you find that the values are abnormal, we recommend the following two operations to restore the data. . Operation 1. After getting the instrument, if you find abnormal data, please power on the product continuously for more than 24 hours. During this period, please ensure that it is in an outdoor ventilated environment for ten minutes so that the instrument can automatically calibrate. Operation 2. When the product is turned off, press and hold the button until the screen displays -CAL and a 200-second countdown appears. At this time, the product should be placed outdoors in a ventilated place immediately until the countdown ends. The instrument now performs automatic calibration. After the calibration is completed, the instrument can perform accurate measurements (when performing operations 1 and 2, be sure to keep it outdoors in a ventilated environment. Operation 1 needs to be kept outdoors for 10 minutes).
