How to calibrate the multimeter
1. First observe the dial of the multimeter, you will see that the multimeter will have many gears, but these gears are all to be calibrated.
2. Then use the standard to calibrate the multimeter. When calibrating the power supply, output voltages +100mV, +1V, +10V, +100V and +1000V respectively, and record the indicated values respectively.
3. When calibrating the DC voltage block of the multimeter, output voltages of 200mV, 2V, 20V, 200V and 1000V respectively, and record the indicated value.
4. When measuring the electronic gear, you need to use a standard resistance box for measurement. The resistance value of the resistance box generally used is 200Ω-20MΩ, and then measure several resistance values and record them separately.
5. The recorded indication value is being compared to see if the error value is within the specified orientation. If it is not, it is unqualified.
The above is the multimeter calibration process. Friends in need can contact Shenzhen Jingyu Aerospace Testing. Shenzhen Jingyu Aerospace Testing is a dual-certified instrument testing organization.
