PURPOSE:To facilitate easy control of recording style for a data logger device, by providing an arithmetic parameter setter corresponding to the cnannel. CONSTITUTION:It is supposed that a data logger records the electric energy equivalent to 4 channels at every hour. In this case, the channels 1, 2 and 4 are used with no use of the channel 3. The input data is given by the pulse, and the electric energy Xm per hour is calculated as Xm=A.Xp. In this case, Xp shows the number of pulses per hour and the coefficient A is the electric energy per pulse and set with every channel by a digital switch group 10. The coefficient A set to O indicates a nonuse of the corresponding channel. Accordingly, the coefficient A of the channel 3 is set to O. As a result, not only a setting of the arithmetic parameter but a use/non- use of channels can be simply set for each application to facilitate easy control of recording style. |
