Note 1：Limited by the physical law of calculating the inclination by measuring the gravity acceleration, the product calibrated angle range (factory setting) is -60~+60 degrees. Beyond this range, the resolution and accuracy of the product will be reduced a lot, and the general accuracy can reach 3-5 degrees or even greater. If not specified, the product measurement range is -60 to 60 degrees.
Note 2: Resolution refers to the minimum variation that can be detected by the sensor while working in its valid range.
Note 3：Under Relative Measuring Mode，without alarm，heartbeat rate once per day，temperature 25℃，calculation equation：
Average operating current = (0.013 * (86400-3-20) + 150 * 3 + 13 * 20) / 86400 = 0.021214 (mA). In the equation, 0.013 represents for the sleep current 0.013mA, 86400 represents for the heartbeat cycle 86400 seconds or 24 hours, 150 is the transmission current 150mA, 3 represents for the transmission time 3 seconds, 13 represents for the transmission waiting for the receiving current 13mA, 20 represents for the reception waiting time 20s.
Theoretical Standby time (year) = 8.5 * 1000 * 0.7 / 0.01214 / 24 / 365 = 32.018 > 10(years). In the equation, 8.5 represents for the battery capacity of 8.5Ah, and 0.7 represents for the battery capacity utilization rate of 70%.
