Abstract

PURPOSE:To make the measuring condition of an optional recording channel copyable as the measuring condition of another recording channel by providing a measuring condition copying control means. CONSTITUTION:When a recording channel whose measuring condition is to be copied and another recording channel to which the measuring condition is to be copied are instructed after the measuring condition copying mode is set through a keyboard 8, a program corresponding to the instruction is made to flow out of a ROM 10. Contents of the measuring condition memories 91-9n of the designated channels are stored in the measuring condition buffer memory 13 of a measuring condition copying control means under the process control performed by a CPU 11 in accordance with the program and the content of the buffer memory 13 is written in the memories 91-9n of the recording channel to be copied. Therefore, the measuring condition of an optional recording channel can be copied as the measuring condition of another recording channel.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a multi-pen recorder, and more specifically, to an improvement in measurement condition settings.

(Prior Art) One type of multi-pen recorder is one that is configured to perform digital processing.

FIG. 4 is an explanatory diagram of the configuration of the main parts of such a conventional multi-pen recorder. In Fig. 4, 1 is an input terminal for an analog measurement signal related to the physical quantity to be measured, and the analog measurement signal applied to input terminal 1 is converted to a constant magnitude by an amplifier 2 whose gain is gt4g1 according to the measurement range. After being normalized, it is applied to an A/D converter 3 and converted into a digital signal. This digital signal is temporarily stored in the measured value memory 4. 5 is a display that digitally displays measurement conditions and measured values. Reference numeral 6 denotes a servo 1liW4 that moves the recording pen 7 according to the magnitude of the measured value, and the magnitude of the measured value is recorded by the recording pen 6 as a continuous line on the recording paper in an analog manner. 8 is a keyboard for setting measurement conditions for each recording channel. 9 is a measurement condition memory that stores the set measurement conditions for each recording channel; 10 is a read-only memory (ROM) that stores fixed data related to measurement and programs corresponding to a series of measurement procedures; 11 is a calculation control unit (C
PU) and is connected to each component via a bus 12.

In such a configuration, the measurement operation is performed based on the measurement conditions and ROM1 set by operating the keyboard 8.
It will be executed according to the program read from 0.

By the way, when performing measurements using such a multi-pen recorder, it is often the case that a plurality of recording channels are set to the same measurement condition.

(Problem to be Solved by the Invention) However, with such a conventional configuration, even if the measurement conditions are the same, the settings must be made by operating the keyboard 8 for each recording channel one by one, resulting in poor operability. It's bad.

Furthermore, if complicated measurement conditions have to be set, there is a risk of setting errors.

The present invention has focused on these points, and its purpose is to provide a multi-pen with excellent operability for setting measurement conditions, allowing the measurement conditions of any recording channel to be copied as the measurement conditions of other recording channels as necessary. The goal is to provide recorders.

(Means for Solving the Problems) The present invention has a plurality of recording channels that record the magnitude of a measurement signal by moving a recording pen using a servo mechanism, and the measurement conditions for each recording channel are set digitally. In a multi-pen recorder, there is a measurement condition memory that stores the measurement condition setting data for each recording channel individually, and a measurement condition memory that stores the measurement condition setting data of any recording channel in the measurement condition memory of other recording channels. A measurement condition copy control means for copying and storing the measurement conditions is provided.

(Example) Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a configuration explanatory diagram showing one embodiment of the present invention, and the same parts as in FIG. 4 are given the same reference numerals. In FIG. 1, reference numeral 13 denotes a measurement condition buffer memory used for copying and storing measurement condition setting data stored in the measurement condition memory of an arbitrary recording channel to the measurement condition memory of another recording channel. Such a series of measurement condition copying operations can be carried out by operating predetermined function keys on the keyboard 8 according to the soft key screen displayed on the display 5 to select and set the measurement condition copy mode, thereby copying the program table in the ROM 10. The measurement condition copy program stored in is read out and executed.

FIG. 2 is a configuration explanatory diagram showing a specific example of the main parts of FIG. 1, and the same parts as in FIG. 1 are given the same reference numerals. In FIG. 2, the keyboard 8 includes a NEXT JIC-14 for switching the functions of the function keys displayed on the display screen of the display unit 5 along with the display, and function as soft keys in conjunction with the display contents of the display unit 5. A plurality of function keys 15 to 18, an entry key 19 for entering setting data, and a plurality of keys 20 to 23 for selecting each item of measurement conditions such as recording speed, measurement range, recording range, and span as a menu. etc. are provided. The ROM 10 stores a measurement condition copy program according to the present invention as a table along with a plurality of programs corresponding to each measurement condition item of recording speed, measurement range, recording range, and span selected as a menu with the keyboard 8. .

The operation of the apparatus configured in this way will be explained using FIG. 3.

FIG. 3 shows an example of copying the range data of the second channel to the fourth channel.

In this case, first push down measurement range -'r-21 to set the range menu mode. As a result, the function key display on the display screen of the display device 5 becomes the channel selection for which the range is to be set. Then, since the channel for which the range should be set is channel 4, the operator presses down function 4-F418. By pressing down the function key F418, the function key displayed on the display screen of the display 5 becomes a function selection in the range menu. However, "copy" is not displayed on the first screen function key display, so the operator presses the next key 14 to switch the function key display. By pressing down the next key -14, the function key display on the display 5 changes to the second screen including "copy". In this manner, with the function key display on the display 5 showing the second screen including "copy", the function 4-F3 17 corresponding to "copy" is pressed down. As a result, the copy program stored in the ROM 10 is executed. The function key displayed on the display screen of the display device 5 selects the channel in which the range data to be copied is set. Then, since the original channel is 2 channels, the operator presses down the function key F216. As a result, the measurement condition data stored in the 2-channel measurement condition memory 92 is copied and stored in the 4-channel measurement condition memory 94 via the measurement condition buffer memory 13. To execute a measurement using the measurement conditions copied and stored in this way, the entry key 19 is pressed down.

As a result, various measurement conditions that require complicated setting operations can be copied and set with a simple key operation, and setting errors can be prevented.

In the above embodiment, an example has been described in which the range is selected as the menu mode and the measurement conditions are copied, but it is also possible to select the recording range or span and copy those measurement conditions as well.

(Effects of the Invention) As explained above, according to the present invention, a multi-pen recorder with excellent operability in setting measurement conditions can copy the measurement conditions of any recording channel as the measurement conditions of other recording channels as necessary. can be realized, and the practical effect is great.
