level developments LD-2M : Dual Axis Inclinometer with Digital DisplayCalibration Testing the Accuracy Please use the following simple procedure to check the accuracy of the LD-2M before using. This should also be carried out if the unit is dropped, or is being used in an environment that varies more than 5°C from the environment in which it was last calibrated. 1) Place the LD-2M down on a clean, flat horizontal surface. The surface does not have to be exactly level. Wait 10 seconds so the display is completely stabilised and note the X and Y angle readings from the display. 2) Turn the...
