Abstract

The invention relates to a controller and a control method for a measuring device, in particular to a device and a method for controlling the screening times for a soil aggregate water-stability measuring device. The invention solves the problem in the conventional soil aggregate water-stability measuring device that the screening times cannot be controlled through an external device. A manual switch is connected in a powder supply circuit of a time relay in series for controlling the on/off of a power supply of the time relay; a toggle switch outputs a screening times signal to the time relay, the time relay sends a delay time signal to a display for displaying the remaining time, and a switch of the time relay is connected in a power supply circuit of a control coil of a switch relay in series for controlling the start or the stop of the switch relay; and a switch of the switch relay is connected in a power supply circuit of a soil aggregate water-stability measuring device in series for controlling the start or the stop of the soil aggregate water-stability measuring device. The device and the method can be widely used for controlling the screening times for the soil aggregate water-stability measuring device.

Description

technical field [0001] The invention relates to a controller and a control method of a measuring device. Background technique [0002] Due to the DM200 series soil aggregate analyzer produced by Shanghai Dema Information Technology Co., Ltd. has the disadvantages of relatively complex technology, large volume and relatively high cost, the reliability of the product is reduced, and it is not easy to transport, requiring a larger laboratory space to accommodate. To this end, the Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences invented a simple device for measuring the water stability of soil aggregates (patent application number: 201210036689.4). This device not only has the advantages of high measurement efficiency of DM200 series products and the simultaneous separation of various particle size aggregates, but also has the remarkable characteristics of simple structure, relatively small volume and low price. But this device can't control the n...
