Abstract

PURPOSE:To efficiently set various measurement conditions by selecting set measurement conditions from the measurement conditions of each measurement channel stored in a measurement condition memory. CONSTITUTION:When an operation designation part 14 is designated to an input mode, the measurement conditions of measurement channels selected in a channel selection part 12 are written in the storing area of a measurement condition memory 11 by the use of a measurement condition memory control part 15. And at the time of a copy mode designation the measurement conditions stored in the storing area of the measurement channels selected in the selection part 12 are simultaneously copied to store to the storing area of a plurality of selected measurement channels. The measurement conditions can be efficiently set, compared with the conventional method independently and individually setting the measurement conditions in every channel because the measurement conditions can be copied in a plurality of the channels by a small number of operation steps according to the method.

A recording unit 8 records various kinds of information including display contents of the display unit 7 on a common recording sheet. Here, a CRT, an EL, a liquid crystal or the like is used as the display unit 7, and a pen recorder for performing ink recording or a thermal recorder for performing thermal recording is used as the recording unit 8.

By the way, in the setting of the measurement conditions of the conventional measuring instrument having a plurality of measurement channels, each of the channels is independently operated according to the operation of the setting section 4, or the measurement condition of any measurement channel is set. The setting conditions are copied to desired measurement channels one by one.

[0005]

However, according to these conventional measuring condition setting methods, the number of operations of the setting unit 4 increases as the number of measurement channels increases, and the operation becomes complicated. In addition, it is quite difficult to individually set values that continuously change, such as the setting of the zero position of the recording position, as equal values to a plurality of measurement channels. The present invention solves such a conventional problem, and an object of the present invention is to realize a waveform display recording apparatus capable of efficiently setting various measurement conditions.

Condition setting section, operation mode designating section that specifies input mode or copy mode when setting measurement conditions, and writing of measurement conditions in the storage area of the selected measurement channel when input mode is specified When the copy mode is specified, the measurement conditions stored in the storage area of the selected measurement channel are stored in the storage area of the multiple measurement channels selected. At the same time copy - measurement condition memory controller for controlling to store, and characterized in that it consists of and.

[0007]

Operation: The measurement condition is written in the storage area of the measurement condition memory of the selected measurement channel with the input mode specified. The measurement conditions stored in the storage areas of the measurement channels are simultaneously copied and stored in the storage areas of the plurality of measurement channels selected when the copy mode is designated. This makes it possible to copy the measurement conditions to multiple channels with very few operation steps.
