Definitions
- the present invention relates to an electronic balance suitable for use in force-relief measurement.
- the purpose (method) of use of an electronic balance is to determine in advance powder, liquid, etc., in contrast to a method that emphasizes the weight of one (or more) mass (hereinafter referred to as “normal measurement”). There is a method (hereinafter referred to as “crushing”) that measures the amount that has been measured.
- the weight to be removed may be coarser than the accuracy of the balance, but the measurement time needs to be shortened.
- the accuracy of measurement is more important than shortening the measurement time.
- Patent Document 1 JP-A-10-19642
- the measurement data obtained every moment is averaged and displayed for a predetermined time.
- the response speed is simply increased. I tried to make it late or late. In other words, depending on the measurement, it was not possible to set the weighing-off weight or the minimum weighing-off weight, and it was impossible to perform the optimum measurement.
- the present invention sets the accuracy of the weighing-out weight and the minimum weighing-up weight in advance, thereby performing the force-removing measurement based on the setting condition and the accuracy of the force-removing measurement. It provides an electronic balance that can be improved.
- the first invention is an electronic balance that has a windshield having an openable / closable door surrounding a weighing pan, averages the load signal by the averaging time or the number of averaged data, and obtains a weighing value based on the averaged balance.
- Door opening / closing detection means for detecting opening and closing, weighing accuracy setting means for setting weighing accuracy, and averaging time or averaging data for weighing measurement that satisfies the weighing accuracy.
- the calculating means for calculating the number of data and the door opening / closing detecting means When the door is opened by the calculating means for calculating the number of data and the door opening / closing detecting means, the above is set as the average time or the number of average data for the force removal measurement, and the door is closed. And a means for selecting the average time of average measurement or the number of averaged data when it is detected, and the averaging process is performed with the selected average time or number of averaged data.
- the second invention has a windshield having an openable / closable door surrounding the weighing pan, and averages the load signal with the averaging time or the number of averaged data, and based on the average, obtains a weighing value.
- the door open / close detection means for detecting the opening / closing of the door
- the weighing scale setting means for setting the minimum weighing weight of the sample placed on the weighing pan in the force measurement
- the weighing scale setting means When the weight of the sample is larger than the minimum weight and when it is detected by the door opening / closing detection means that the door is opened, the averaging time or the number of average data is set in advance.
- a selection means for setting the averaging time for the force measurement or the number of averaged data, and averaging processing is performed with the selected averaging time or averaged number of data.
- a third invention relates to the weighing accuracy setting means for setting the weighing accuracy in the first invention, and the averaging time for averaging measurement or the number of averaged data pieces satisfying the weighing accuracy.
- a calculating means for calculating, and the averaging time for measuring and measuring or the number of averaged data is calculated by the calculating means.

- Fig. 3 is a configuration diagram of processing functions of the electronic balance according to the present invention
- Fig. 4 is an electronic balance according to the present invention. It is a flowchart of the process of.
- a weighing pan 53 provided on the load detection unit 1 and on which a sample is placed is accommodated in the windshield 51.
- the windshield 51 is provided with a door 52, and 6 is a display for displaying a measured value.
- the load detection unit 1 is connected to the processing device 2, and the precision of peeling (from the input device 4 such as a key switch or a personal computer or an external keyboard connected to the processing device 2) For example, weight values such as lmg, 0.1 mg, 0. Olmg, weight digits that you want to read accurately, etc., and the minimum is the force weight (for example, the force weight is always 2 mg or more).
- the data is input and stored in the storage device 5 via the processing device 2.
- the display 6 displays a measured value obtained by converting the load detected by the load detection unit 1 into a weight value.
- the weighing accuracy and the minimum weighing weight can be configured so that both or either can be entered and set.
- the measurer inputs the force removal accuracy required for force removal work from the input device 4. Enter the minimum weighing weight in the same way. These values can be entered either or both. These input data are digitized by the force removal accuracy Z amount input determination function 28 via the input processing function 29 and passed to the average time calculation / determination function 27. Further, it is stored in the storage device 5 through the storage device input / output function 2a. [0016] The average time calculation 'determination function 27 calculates and determines the number of average data and the average time to obtain the necessary force removal accuracy. The number of averaged data and the averaging time can be stored in the storage device 5 via the storage device input / output function 2a.
- the door 52 of the draft shield 51 is opened. At this time, the work is performed with the door 52 left open.
- the door open / close judgment function 26 determines that the door 52 has been opened, it becomes the force removal measurement mode, and when the force removal accuracy is low, the average time calculation • determination function 27 determines the relatively short average. Speed up the display response with the conversion time.
- the display is stabilized with a relatively long averaging time, which is determined by the average time calculation / determination function27.
- the averaging time is lengthened to stabilize the display regardless of the force removal accuracy. Inform the measurer of highly reliable V ⁇ measurement values.
- the weighing pan measurement mode is set and preset or averaged.
- Time calculation / determination function 27 The average determined by the averaging time for the force measurement or the number of data to be averaged is made to respond relatively quickly.
- the door 52 is closed, the weighing measurement mode is canceled, the averaging time is lengthened, the display is stabilized, and the measured value is reported to the measurer with high reliability.
