Data 20Setup exe Furthermore the controller box is connected directly to the depth encoder thus providing the encoder with the excitation in addition to receiving and analysing the encoder signals The controller box saves the Depth Ovality Maximum Diameter and Minimum Diameter data at every depth measure unit example ft or m in it s own memory This is done automatically and the existing data is over written if the same depth is reached Thus in the case of changing the coiled tubing it would be necessary to re initialise the memory so as not to confuse the data of different coiled tubing strings Using the Menu Buttons The menu buttons can be used to perform any one of three functions The buttons are activated by pressing and releasing To enter in the menu mode use the left most button Then use the middle buttons to scroll through the menu options Set Depth Set K Factor Initialise Memory Use the right most button to select the required function then use the left most button to move left wards 1 e like left arrow and the right most button to move right wards i e like right arrow Once the digit that requires changing is highlighted flashing then use the middle buttons to increase or decrease the value Once finished editing the value scroll the right most digit then use the right most button to exit the editing mode Finally use the right most button again to SAVE the changes Cables Bundle A cable bundle co
