Overview
The Wasites WT811 AC parameter measurement instrument (harmonic type) uses a high-speed DSP processor and phase-locked loop (PLL) technology, combined with low-temperature bleaching resistance or High Accuracy transformer sampling, to ensure that the signal is not infiltrated and provide stable and accurate measurement. The instrument has true effective value (RMS) measurement function, which can measure voltage, current, Power, Power Factor, Frequency, Voltage Crest Ratio, Current Crest Ratio, and supports harmonic analysis and serial communication. Its complete functions, superior performance and simple operation are suitable for high-speed measurement in production sites and laboratory R & D requests.
Features
1. Four windows simultaneously display Voltage, Current, Power, Power Factor/Frequency
2. Adopt high-speed DSP + PLL design to accurately calculate voltage and current harmonic distortion and absolute value
3. Adopt Zero Flux Checker, High Measurement Bandwidth, Ensure Measurement Accuracy and Stability
4. Data locking, alarm mute function
5. Can arbitrarily set the upper and lower limit alarm parameters, sound and light alarm functions, support qualified or unqualified alarms and delayed alarms, batch detection to improve efficiency
Principle
The instrument consists of an analog part and a digital part. The analog part includes a Sensor, a multi-speed programmable amplifier, a sampling holder and an A/D conversion circuit; the digital part includes a microcomputer, a Data storage device, a keyboard and a display. The measured voltage signal is converted into a weak signal through the voltage Sensor. After being programmatically amplified, sampled and held and A/D converted, the voltage true effective value (URMS) is calculated and displayed by the microcomputer. The measured current signal is converted into a weak voltage signal through the current Sensor, and the current true effective value (IRMS) is calculated and displayed by a similar processing flow.
Applications
Production lines, laboratories, and Quality control departments of manufacturers in the fields of lighting appliances, electric tools, household appliances, motors, electric heating appliances, etc
Steps
1. Connect the device under test to the instrument's voltage and current input ports
2. Turn on the power of the instrument and select the normal mode or harmonic mode according to your needs
3. The instrument automatically performs range selection and parameter measurement, and displays data such as voltage, current, Power, Power Factor/Frequency
4. If you need the alarm function, set the upper and lower limit parameters and delay options through the keyboard
5. Observe the display results and use the data lock or alarm mute function for data recording or processing
