Range correction board

Range Correction. Changes of firing data necessary to allow for deviations of range due to weather, materiel, or ammo Range Correction Board. Device with which the correction to be applied to a gun is computed... 

Now measure one of your resistances with the multimeter as follows. Insert the wire ends into two sockets on the socket board so that they are not connected internally, such as in sockets FI and F5. (You will have to bend the end wires at about a 90° angle.) Measure the resistance with your multimeter by setting the selector switch to measure resistance and then contacting the lead tips to sockets that make contact with FI and F5, such as G1 and G5. You may have to adjust the selector switch to the proper range for the resistor being measured. Record the value in your table. Measure all the other resistors in the same way. Determine if the accuracy of each, as indicated by either the gold or silver stripes, is correct based on your data and comment on this. 

Creasability of boards BS 4818 1993 described the method of determining the creasing quality of cartonboard within the range of 300-1000 4m. This is important to the packaging line, since if the creases are not correct and do not assist the carton erection, the cartoning machine will not function correctly. 

Other reasons for the process models to diverge from the true system state may be more subtle. Information about the process state has to be inferred from measurements. For example, in the TCAS If aircraft collision avoidance system, relative range positions of other aircraft are computed based on round-trip message propagation time. The theoretical control function (control law) uses the true values of the controlled variables or component states (e.g., true aircraft positions). However, at any time, the controller has only measured values, which may be subject to time lags or inaccuracies. The controller must use these measured values to infer the true conditions in the process and, if necessary, to derive corrective actions to maintain the required process state. In the TCAS example, sensors include on-board devices such as altimeters that provide measured altitude (not necessarily true altitude) and antennas for communicating with other aircraft. The primary TCAS actuator is the pilot, who may or may not respond to system advisories. The mapping between the measured or assumed values and the true values can be flawed. 

Alarms Process parameters (levels, temperatures, pressures, flows) are automatically controlled within a permissible range. If the parameter moves outside this range, it sometimes activates both an audible and a visual alarm. If the panel board operator fails to take corrective action, a trip may also then be activated.
