3、 Usage method
1. Gear switch selection: Choose the appropriate gear according to the measured instrument.
2. Selection of city frequency and standard frequency: Choosing city frequency can eliminate the impact of beat frequency and improve stability; Use standard frequency when checking the frequency meter.
3. Current switch: Open when using current and close when wiring.
4. Voltage and current output terminals: can be used front and back. Connect the tested meter to the front and the standard meter to the back. But please note that the voltage terminal must not be short circuited, and the current terminal must not be open circuited. Please short-circuit the current terminal on the back board when not in use.
5. Keyboard operation introduction: If the keyboard displays 0000 after booting up, it means the machine is normal and can be used. 0-9 are numeric keys. Voltage, current, phase, and frequency are function keys. The reset button is used to reset to zero.

4、 Completeness
YS106B single-phase programmable power supply with PF108 digital AC multifunctional meter produced by the meter (this meter automatically converts voltage and current ranges, is versatile, easy to operate, has good stability, comes with a computer interface, accuracy level 0.1, range 650V, 20A). It can simultaneously measure seven electrical parameters including AC voltage, current, power factor, frequency, phase, and DC voltage. Equipped with the PS74 single-phase standard power electric energy meter produced by our factory (this meter adopts microcomputer intelligent digital control. It has high accuracy, good linearity, and high degree of automation. The accuracy is 0.05 level, and the range is 220V, 5A). Suitable for the calibration of single-phase energy meters and power meters.
The YS106B single-phase program-controlled power supply is paired with our factory's YJ85A high stability DC stabilizer, YJ86A-2 high stability DC stabilizer, and cabinet to form a combined drawer style precision AC/DC power supply device. It has adjustable continuous output of high voltage and high current for both AC and DC, without the need for external YJ5 voltage regulators and YJ6 current regulators. It is compact in structure, easy to move, has high self power, strong load capacity, low distortion, and good stability. Especially, the AC YS106B single-phase programmable power supply uses a computer-controlled keyboard to adjust the output, with small phase error and easy operation. According to the stability indicators of this power supply, appropriate AC/DC standard meters can be selected and used as precision working power sources for measuring instruments such as AC/DC voltage, current, power, power factor, frequency, phase, etc. below level 0.1 in various provincial and municipal metrology testing institutes, power systems, electrical metrology of large and medium-sized enterprises, electrician laboratories, and instrument production plants.
