SINOTIMER SPM004 Single-Phase Digital Display Voltage Current Frequency Power Factor Electricity Multifunctional Measuring Instrument, Specification: AC50-300V

Description

1. Can simultaneously measure and display AC voltage, AC current, active power, power factor, frequency and electrical energy and other six parameters
2. The instrument display part adopts colorful high-definition liquid crystal display, the data is clear at a glance
3. Save function/memory function: when power down, the meter will automatically save the current power value, and after the next power on the meter will read the value, and continue to accumulate
4. Use and wiring method:
- Wiring according to the attached wiring diagram, insert the two-wire plug at the secondary end of the current transformer that comes with the meter into the secondary input of the transformer of the meter, and pass the main circuit lead of the current test through the middle hole of the current transformer
- Connect the voltage measurement lead to the measurement voltage input terminal of the meter, and then turn on the measurement voltage to start reading the measurement result
- The power reset button is located on the lower right side of the meter, when you need to reset the power, use a round cudgel with a diameter of less than 2mm to gently press and hold it inside the reset hole for 5 seconds, then the accumulated value of the power can be restored to zero
