Chapter 2 Product Introduction
2.1 Product Overview
smart digital power meter is an economic and portable measuring instrument. It is a multi-
functional measuring instrument which integrating voltage, current, power, power factor and frequency. The
products is widely used in production, testing, evaluation and scientific research and multi-field.
digital power meter adopts high speed CPU for data processing, the sampling resistance of
voltage and current are all use low temperature drift resistor, therefore, the stability and accuracy of
measurement data are guaranteed.
has true RMS measurement, it can adjust to the electric parameter measurement of various
occasions such as full wave, half wave (AC/DC type) and irregular waveform. This instrument can measure
voltage (V), current (A), active power (W), power factor (PF) and frequency (Hz). It has perfect functions,
superior performance and simple operation.
The instrument can meet the needs of high-speed measurement in production sites, as well as laboratory
and R&D measurements. It is widely used in in the fields of lighting appliances, power tools, household
appliances, electric motors and electric heating appliances of production lines, laboratories and quality
inspection departments.
Characteristics
1. VA broken code screen display for intuitive reading. It adopts high speed A/D transformer and 32-bit MCU
operation.
2. Multi-window simultaneous display of voltage, current, power, power factor/frequency.
3. The range of voltage and current has manual range and automatic range.
4. AC, DC, AC+DC (T-RMS) mode.
5. Average function can make the reading more stable and it suitable for measuring the load or power with
large variations.
6. Data upgrade period can be set. User can select a faster upgrade period according to the test needs, so
as to improve the test efficiency.
7. Communication interface supports RS-232 and RS-485. Communication protocol supports SCPI and
Modbus for communicating with computer and PLC.
8. It can freely set the upper and lower limit of current and power, the digital power meter will automatic
judge whether the test value is exceed. Sound and light alarm indication, it is convenient for batch
detection to improve the measurement efficiency.
