PF109-1 type electrical parameter measuring instrumentDetailed product description：

The PF109-1 electrical parameter measuring instrument adopts digital synchronous sampling and microcomputer technology to accurately measure the input parameters of single-phase and three-phase electrical equipment, including voltage, current, power, true effective value of power factor, and frequency. The measurement accuracy is 0.5/0.2 level, which has the advantages of fast testing speed, high accuracy, easy use, lightweight and beautiful appearance. Widely used in product testing and measurement for manufacturers and quality inspection departments in industries such as motors, water pumps, transformers, household appliances, electric tools, and power control. This instrument is an ideal replacement for traditional electrical parameter testing instruments.

Main features of PF109-1 electrical parameter measuring instrument
l、 Using a four window (16 bit LED) digital display, measure parameters such as three-phase voltage, current, power, power factor, frequency, etc.
2. Multiple voltage and current ranges, with automatic range switching to ensure measurement accuracy throughout the entire measurement range.
3. Ensure accurate measurement of power factor, especially suitable for testing low power factor loads.
4. Strong real-time performance, fast testing (display refresh) speed, about 3 times per second.
5. The measured data is stable and the reading repeatability is good.
6. It has complete overvoltage and overcurrent protection functions.
7. It is possible to set the current rate, wave holding capacity, and multi machine communication address code separately, and memorize the set values (which can be saved when the power is turned off).
8. External current transformer can be used to expand the current range, set the current multiplier, and read the current value directly.
9. Suitable for input electrical parameter testing of single-phase (50/60Hz) and three-phase (three-phase three wire system, three-phase four wire system) electrical equipment.
10. During the testing process, the measured parameters can be printed at any time by pressing the print button, and can communicate with the computer (communication software is required) for data acquisition, analysis, archiving, and instrument control.
11. Strong anti-interference performance, stable performance, and easy operation.
