Abstract

PURPOSE:To enable a measurement data at an arbitrary point to be stored easily by providing a storage key and a storage memory and then operating the storage key with a switch for storing a measurement value at that time in the storage memory. CONSTITUTION:A storage key 7, a storage recall key 8, and a storage memory 9 are provided additionally. They key 7 has a function for notifying a timing for storing a measurement value at the memory 9 to a control part. When the key 7 is pressed during measurement, a measurement value at that time is read from a measurement block 2 and is stored in the memory 9 or a data is updated if the measurement value is already stored in the memory 9. The measurement value which is stored in the memory 9 is recalled by the key 8 as needed and is displayed 5 and recorded 4 or is supplied as a reference of a setting value which is stored in a setting value memory 3, thus eliminating a need for writing the measurement data on a recording paper, etc., and a need for directly inputting a numeric value when inputting the numeric value such as the setting value.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to digital measuring devices and, more particularly, to storing measured values.

[0002]

2. Description of the Related Art In a digitized recorder, in addition to recording the original measurement signal on a recording sheet, a large amount of data is stored on a recording medium such as an IC memory card or a floppy disk which can be easily attached to and detached from the recorder body. The measurement data of is stored.

FIG. 3 is a block diagram showing an example of such a conventional recorder. In the figure, reference numeral 1 denotes a recorder main body, which is a measurement block 2 for measuring a measurement signal, a set value memory 3 for storing set values related to a measurement operation, and a record for recording a result measured by the measurement block 2 on a recording sheet. The block 4 and the measurement block 2 are composed of a display 5 for displaying the results measured.

Reference numeral 6 is a storage medium that can be attached to and detached from the recorder main body 1. Measurement data is stored in the storage medium 6 as needed, and the measurement data stored in the storage medium 6 is recorded in the recording block 4 or displayed on the display 5 as necessary.

Incidentally, for example, a reference output is generated to calibrate the input before the measurement is started, the voltage at that time is stored, and after the measurement is finished, the measurement data is processed based on the voltage corresponding to the reference output. I have something to do.

In this case, what temporarily stores a small number of measurement data such as one point or several points has not been put into practical use. For this reason, under the present circumstances, although the user has the function of storing a large amount of measurement data in a storage medium that can be attached to and detached from the main body, the user bothers to write down one or several measurement data on a recording paper. is doing.

This is not limited to calibration, but it should be noted that the recorder has a function of displaying the measured data when a specific phenomenon occurs during the measurement recording operation. Sometimes.

As a countermeasure against this, in a recorder configured to record an event mark, an event mark is recorded when a specific phenomenon occurs, and after measurement, the position of the recording paper to which the mark is attached is recorded. The measurement data of is read.

[0009]

However, in any case, it is necessary to leave a memo or read the measurement data from the recording paper, and the workability is poor.

The present invention has been made in view of the above problems, and an object thereof is to realize a digital measuring device capable of storing measurement data at an arbitrary time point in a memory like a memo. Especially.

[0011]

SUMMARY OF THE INVENTION An invention for solving such a problem is a digital measuring device for converting a measured value into digital data to perform a measuring process, wherein at least a storage key and a storage memory are provided, and the storage key is provided. When the switch is operated, the measured value at that time is stored in the storage memory.

[0012]

Since the measured value at that time is stored in the storage memory by operating the switch of the storage key, the conventional memo work can be omitted.

Further, by using the measurement data stored in the storage memory, it becomes unnecessary to input a numerical value for the set value.

[0014]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention, in which the same parts as those in FIG. 3 are designated by the same reference numerals. The difference from FIG. 3 is that a memory key 7, a memory call key 8 and a memory 9 are added.

The storage key 7 is for notifying a control unit (not shown) of the timing of storing the measured value in the storage memory 9, and in the specification of the present application, any key having the same function is referred to as a key. The memory recall key 8 is a key for recalling the measured value stored in the memory 9, and if the memory recall key 8 also has an equivalent function, it is referred to as a key. In addition, although these are illustrated one by one, a plurality of sets of these may be provided so that a plurality of measured values can be stored.

The operation of such an apparatus will be described. By pressing the memory key 7 during measurement, the measured value at this time is read from the measurement block 2 and stored in the memory 9. When the measured value is already stored in the storage memory 9, the content will be updated.

The measured values stored in the storage memory 9 are recalled by the storage recall key 8 as necessary, and the display 5
Is displayed, is recorded in the recording block 4, and is referred to the set value stored in the set value memory 3.

A specific application will be described. An example of performing linear scaling calculation with a recorder will be described. Basically, the voltage input for two reference physical quantities within the measurement range is given, and the physical quantity for the voltage input between them is read. When the voltage inputs for the reference physical quantities P1, P2 are V1, V2, the physical quantity Px for the input voltage Vx is given by the following equation.

Px = P2 + {(P1-P2) / (V1-V2)} (Vx-V2) When this formula is input as an arithmetic expression, P1, P2, V1, V
2 was conventionally treated as a constant. It was extremely complicated in operation to measure V1 and V2 and rewrite this constant in each calibration before the measurement. In particular, in the case of an on-site measuring instrument, these must be rewritten at the measuring site, and it is necessary to measure the voltage values V1 and V2 and store them in the head or make a note of them.

However, the present invention can be realized as follows. Prepare two memory keys, two memory recall keys, and two memory memories, and number them 1 and 2. Instead of directly inputting the voltage value where V1 and V2 are specified in the arithmetic expression, memo1 and memo2 are specified by the memory recall key. When calibrating before measurement, the reference physical quantity P1 is given and the memory key 1 is pressed to store the voltage value at this time in the memory memory 1, and similarly, the reference physical quantity P2 is given and the memory key 2 is pressed. The voltage value at that time is stored in the storage memory 2. By doing so, physical quantity conversion suitable for this calibration is executed at the time of measurement. FIG. 2 shows these relationships.

Further, if the subsequent measurement also requires calibration in advance, the measurement can be performed as it is by simply applying the voltage of the reference physical quantity and pressing the memory key without returning to the setting.

When the voltage value corresponding to the reference physical quantity is left as a test material after the measurement, it can be printed out by a printing process. Although the storage key is used to notify the storage timing in the above-mentioned embodiment, the key need not be limited to the key as long as it has the same function. For example, a communication command by full remote may be given to the recorder, or contact input may be prepared in the recorder so that the recorder can detect the change state of the contact.

The keys are not limited to dedicated keys, but function keys or the like may be used. In the setting, the storage memory is specified by the setting item, and the run-time reference that refers to the newly specified storage memory when referring to the set value has been described as an example. A setting reference method may be used to reflect the value in the setting value.
Explaining in the above example, when setting the value of V1 to the constant H
When memo1 is pressed, memo1 does not remain in the setting, but if the value of 0.0832 is stored in the storage memory, the set value will be 0.0832 (the display of the constant setting part will be H = 0.0832).

Further, in the embodiment, the description has been made by referring to the contents of the storage memory by using the storage call key, but the call key is omitted and, for example, the contents of the storage memory are automatically displayed in the display of the setting screen. It may be referred to, or a command or function may be described by a character string in the setting, and this may refer to the contents of the storage memory. For example, 1) When the specific setting screen is expanded, the latest data in memory 1 and memory 2 are displayed.

2) When a reserved word to be M1 and M2 is described in the arithmetic expression, this automatically refers to memory 1 and memory 2. In the embodiment, the display contents are used to confirm the stored contents. However, if the contents are output in a form that can be confirmed by the user, these may be directly or indirectly. Specifically, 1) printer print output 2) voice output 3) digital output (character code, binary data), etc. are considered, and the output is finally recognized by the user (including the computer). I wish I had it.

Furthermore, although an example of a recorder has been described in the embodiment, it can be widely applied to various digital measuring devices in general.

[0027]

As described in detail above, according to the present invention, the memory key and the memory are provided to fulfill the conventional user memo function, so that the user can transfer the measurement data to the recording paper or the like. Since it is not necessary to make a memo, a memory recall key is prepared to refer to the contents of the memo to enter a numerical value, so it is not necessary to directly enter a numerical value for setting values etc. Be done.
