2.1 Product Overview
Digital power meter is an economic and portable measuring instrument, integrating voltage, current, power,
power factor and frequency as a multi-functional measuring instrument with cost-effective, which is widely used
in production, testing, evaluation and scientific research and other multi-field.
UTE9802 digital power meter adopts high speed CPU for data processing, voltage and current are sampled by
low temperature drift resistor or high precision transformer, so that the sampled signal is not filtered to ensure
the stability and accuracy of measurement data.
UTE9802 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 P F 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 Various measurement functions can also be customized according to user requirements to meet
higher applications.
Characteristics of UTE9802
1.VA broken code screen display，reading intuitive, it adopts high speed A/D transformer and 32-bit MCU
operation.
2. Multi-window simultaneous display of voltage, current, power, power factor/frequency. With stable
measurement and fast measurement.
3. Automatic switching of voltage and current ranges to improve measurement accuracy.
4. Measurement accuracy is not affected by waveform, the instrument is high reliability and long life.
5. AC-DC type is more suitable for half-wave rectification measurement, it also can measure the AC component
in DC, as well as can be suitable for measuring the DC component in AC, true value (AC + DC).
6. It equipped with RS-232 and RS-485 serial communication interface to communicate with computer or PLC.
7. It can freely set the upper and lower alarm parameters of current and power, sound and light alarm
indication, and can set the delay alarm, batch detection to improve efficiency.
8.Communication address：1~32（only for MODE BUS protocol），baud rate：4800, 9600, 19200
UTE9811 digital power meter adopts high speed DSP processor and PLL (phase-locked loop) for data processing,
voltage and current are sampled by low temperature drift resistor or high precision transformer, so that the
sampled signal is not filtered to ensure the stability and accuracy of measurement data.
UTE9811 has true RMS measurement, it can measure voltage, current, power, power factor and frequency, voltage
crest ratio, and current crest ratio, with harmonic wave analysis and serial communication function.
The instrument has perfect functions, superior performance and simple operation. It 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.
