The measurement steps are as follows: 1. Measure the digital multi-meter voltage and high resistance = resistance (100.0001 kohm to 100 megohm); 2 • measure digital multi-purpose 1 Table 3 ^ electric current, 3 · 1 multi-digit multi-meter 3 〇 low impedance resistance (thousands of ohms). Among them, voltage measurement includes DC voltage measurement and AC corpse, volume measurement, including DC current measurement and AC current measurement, including low impedance resistance measurement and high impedance resistance measurement. After the completion of step 2 in step 1, the specific connection of each step of the need to change the digital multimeter 3 and the calibrator is as follows. . , connection, when measuring digital multi-meter 3G and high-impedance resistance, use the common 埠31 of Table 3G and the ohms/resistance of calibrator 2() is low. 'Continuous' digital multi-meter 30 voltage/resistance 埠32 and calibration cry The high-end resistors 22 are connected, as shown in Μ1. When the electric house is measuring the current of the 1 digit multimeter, the digital multiplexer 31 of the digital multimeter is connected with the low current terminal 24 of the calibrator 2〇, and the current 埠33 of the digital multi-position and the high current of the calibrator 2〇 The conveyor is called 2. When the low-impedance resistance of the meter is used in the multi-meter meter, the public 璋31 of the digital multi-meter table 9 200817709 30 is connected to the voltage/resistance low end 21 and the current low end 24 of the calibrator 20, and the multi-digit multimeter 30 The voltage/resistance 埠32 is connected to the voltage/resistance high side 22 of the calibrator 20 and the AUX auxiliary 埠25, as shown in FIG. During the measurement process, the control computer 10 sends a measurement command for measuring a standard value to the calibrator 20. The calibrator 20 outputs a signal of the standard value to the digital multimeter 30 according to the command, and the digital multimeter 30 performs the signal multiple times. The measurement is returned to the control computer 10 . The control computer 10 averages the plurality of measured values as the measured value of the digital multimeter 30, and then compares the measured value with the standard value to determine whether the measured value is within the error range, and the judgment formula is: the standard value X (1) -X%)=<measured value<=standard value X (1+Y%), and the magnitude of X and Y depends on the case. For example, the control computer 10 sends a measurement command for measuring the 5V voltage (standard value) to the calibrator 20, and the calibrator 20 outputs a 5V voltage signal to the digital multimeter 30 according to the command, and the digital multimeter 30 performs the voltage signal multiple times. The measurement is made and the measured value is returned to the control computer 10. The control computer 10 averages the plurality of measured values (for example, 4.9998V), and then compares the measured value with the standard value to determine whether the measured value is within an allowable error range, assuming that the X value is 0.036 in the judgment formula. If the Y value is 0.038, the measured value can be judged to be accurate because 5 X (1 - 0.036%) = < 4.9998 <= 5 X (1 + 0.038%).

The formula is · standard value X measured value < = standard value X (1 + Υ%), and the magnitude of X and γ depends on the specific situation. Step S407, generating a measurement report according to the comparison result between the standard value and the measured value measured by the digital multimeter 30, and marking the measurement point whose measurement value is within the error range as a measurement pass (pass), and the measurement value is not within the error range. The measurement points are marked as Failed. The digital multimeter can automatically measure one or more of measuring only voltage (including DC voltage and AC voltage), current (including DC current and AC current), and resistance (including high impedance resistance and low impedance resistance). The order of measurement can also be adjusted. I.
