A single WT1600 unit can make up to six different power measurements (six input each for voltage and current). With the measure start-stop function (synchronized measurement), two WT1600 units (12 inputs) can be synchronized.
The WT1600 has two different input elements. A 5 A input element is provided for measuring extremely small currents, while a 50 A input element serves to measure large currents.
Both of the elements can be installed together in the WT1600.
The current for the 5 A input element can be set as low as 10 mA for measuring extremely small currents in energy-saving equipment.
50/100/250/500 mV, 1/2/5/10 V (DC, 0.5 Hz to 500 kHz)
The data can be stored at intervals as short as 50 ms. The WT1600 rapidly calculates input parameters such as rms voltage, rms current, and power. Measurements can be stored in a 11-MB internal memory, which is helpful for applications such as:
The WT1600 has a higher measurement accuracy than any instrument in its class.
It also features a 1 MHz measurement bandwidth (voltage, current) effective for such things as the evaluation of high-frequency illumination devices using inverters.

In addition to numerical data, the WT1600 can display input signal waveforms. Eleven different display formats can be selected on a single WT1600 unit, so it is not necessary to connect an external waveform viewer to check waveforms.
The WT1600 displays measurements for each display updating interval in a time series. The time axis (T/div) can be set in the range of 3 seconds to 24 hours (wave off).
Changes in up to 16 different parameters, such as voltage, current, active power, and apparent power, can be observed simultaneously in long-term continuous tests.
For High-Precision Measurements
Accuracy is assured at input ranges of 1% to 110% for AC, and 0% to 110% for DC. (However in the case of AC, it is necessary to input either a voltage or current that exceeds 10% relative to the range in order to have the voltage and current rms values calculated precisely.)
The diagram shows the effective input measurement range (AC voltage and AC current from 1% to 110%) at which accuracy is assured, by range-value rating. When using a 1 A range-value, accuracy is assured down to 10 mA. Also, DC voltage and DC current have assured accuracy from 0% to 100%.
Since the voltage and current ranges are fixed during the integration mode, the WT1600's assured accuracy over a wide range makes it a very useful tool.
The WT1600 stands out when it comes to measuring equipment with large input fluctuations such as intermittent control devices and copiers that can repeatedly alternate between normal operation and sleep mode.
The harmonic measurements function is a standard feature on the WT1600. It is capable of measuring waveforms with a fundamental frequency ranging from 10 Hz to 1 kHz. Analysis results up to the 100th order from 50/60 Hz fundamental waves can be displayed as numerical values or bar graphs. The WT1600 can display harmonic measurement result as lists, and fundamental waves as vectors.
Ethernet Port (10 BASE-T) and Internal Hard Drive (optional)
The Ethernet function allows you to use FTP server, FTP client, Network printing, Automatic Mail Transfer (SMTP), and others.
|Motor Evaluation (optional) |
The WT1600 can measure the output from a speed and torque sensor on the output of an electric motor, and calculate torque, rotating speed, mechanical power, synchronous speed, slip, motor efficiency, and total efficiency. Both analog and pulse inputs can be accepted from the sensor. In addition to numerical values, waveforms can be displayed to provide a visual picture of fluctuations in parameter values.
D/A Output (30 channels)
SCSI interface (optional)
With the SCSI interface, you can save measured data to
