Chapter 2 Product Introduction

2.1 Product Overview

UTE9811+ 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 harmonic wave.

The products is widely used in production, testing, evaluation and scientific research and multi-field.

UTE9811+ smart 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.

The instrument can measure voltage, current, power, power factor, frequency, voltage crest ratio and

current crest ratio. It also has harmonic analysis and serial communication function.

The instrument has perfect functions, superior performance and simple operation. It meets 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, householdappliances, electric motors and electric heating

appliances of production lines, laboratories and quality inspection departments.

Characteristics

1. VA broken code screen display for intuitive reading.

2. Multi-window simultaneous display of voltage, current, power, power factor, frequency, voltage crest ratio,

current crest ratio and harmonic measurement data.

3. Harmonic measurement adopts phase-locked loop (PLL) synchronization method. The maximum of

harmonic analysis is 50 times.

4. Voltage and current range can switch automatically, It will help for improving the measurement accuracy.

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.
