Vector Signal Analyzer + EMI PreCompliance analysis
Vibration analysis and sound meter
he WT300's wide range of funcations and enhanced specifications allows to handle all the measurement applications from low-frequency to high frequency inverters using a single power meter.
Accuracy with fast display and update rate:
The WT300 series with the fast display and date update rate of Max. 100ms offers the customer a short tact time in their testing procedure. The basic accuracy for all input ranges is 0.1% rdg + 0.1% rng (50/60Hz) and DC 0.1% rdg + 0.2% rng (0.2% + 0.2% for 40A).
U/I/P/Freq/Integ(+/-)/Harmonics components/ THD with max. 100ms cycle.
In addition to standard power measurements, the WT300 offer a wide range of harmonic measurement capabilities, including the ability to carry out simultaneous measurement of normal power parameters such as RMS, mean or DC power along with measurement of harmonics up to the 50th order. As a result, overall measurement times are reduced, allowing users to allocate their effort and time to other tasks.
Auto ranging function available in selected ranges.
The auto-range function is used to select or change the range automatically in specific ranges. This results in shorter range changing times, allowing more quick and efficient testing.
Auto Ranging Function For Integration Measurement.
Typically, when power meters operate in an integration mode to measure power consumption and standby power, the measuring ranges need to be fixed. However, if the level of the input exceeds the maximum of the selected range, the test will need to be repeated. The WT300 Series has a high speed automatic ranging capability in integration mode, which removes the need to repeat any test.
Bandwidth: DC and 0.5Hz to 100 kHz (WT310HC is up to 20 kHz for 40A).
Direct Input: Maximum direct input up to 600V and 20A, or 40A (incase of WT310HC). The wide current input range gives the customer options to use the WT300 series from as low as 50 micro-Amps to 40Arms.
High-speed data update (up to 10 readings per second.)
|The WT300 series offers a wide range of communication interfaces such as USB, GP-IB or RS-232 (selectable) and Ethernet (Optional)|
Allows users to have the flexibility to choose according to applications needs. Using the WTViewerFreePlus software to set up all kinds of measurements. Additionally, the numeric values, waveform display, and trend graphs of the measurement data can be displayed and saved.
|D/A output for measurement recording|
The D/A option is used to output Voltage, Current, Power, and other measured data for recording to data loggers (+/-5Vdc outputs).
Two new functions, Manual Range Mode and Comparator Mode can be used conveniently with built-in PLC and recorders in production line inspection systems.
|Manual Range Mode|
The default settings will set D/A output value to rated value of measurement range. In this mode, D/A output can be zoomed in and out on each channel by arbitrarily setting the display value of measurement items when D/A output is either -5V or +5V. For example, if you measure the fluctuating current from 0.6A to 0.8A by 1A current range with D/A output range mode switched to fixed range mode, the D/A output voltage will fluctuate from 3.0V to 4.0V. The D/A zoom function is available for enlarging and observing this fluctuating value. Set the D/A output range mode to manual range mode with minimum value set to 0.6A and the maximum value to 0.8A. Then, when the current value measured is 0.6A, the output will be -5V, and when it’s 0.8A, the output will be 5V.
This mode will compare measured, computed, and integrated values with previously set determined value by the communication command, and output (from -5V to +5V) determined results by D/A output. If you are going to use a relay contact output, please prepare the relay and the relay drive circuit.
The upper and lower limit value of Comparator Mode
The following are the D/A output during the Comparator Mode
* The above 2 modes can only be set by the communication command.
* Both modes can be set for all D/A output items.
