Chapter 2 Product Introduction
2.1 Product Overview
The 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, frequency and harmonic wave.
The product is widely used in production, testing, evaluation and scientific research and multi-field.
UTE9800+ series include three models: UTE9802+, UTE9806+, and UTE9811+. It 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.
UTE9800+ series 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), apparent power (VA), voltage peak (Vpk), current peak (Apk), power
factor (PF), frequency (Hz), harmonic wave and wave crest ratio. 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
VA broken code screen display， reading intuitive, it adopts high speed A/D transformer and 32-bit MCU
operation.
The parameters measured in each window can be switched (UTE9806+ only).
Multi-window simultaneous display of voltage, current, power, power factor/frequency.
The voltage and current peak ratios can be measured (UTE9811+ only).
The range of voltage and current has manual range and automatic range.
AC, DC, AC+DC (T-RMS) mode (UTE9802+ only).
The harmonic measurement can be taken. The harmonic testing uses phase-locked loop (PLL)
synchronization method, and the harmonic analysis is up to 50 times (UTE9811+ only).
Average function can make the reading more stable and it suitable for measuring the load or power
with large variations.
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.
Communication interface supports RS-232 and RS-485. Communication protocol supports SCPI and
Modbus for communicating with computer and PLC.
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 (UTE9806+ can also set and check the upper and
lower limit of voltage, apparent power and power factor).
