<\/p>\nSimultaneous measurements of up to 6 input channels can be performed at a speed of 2 MS\/s (16 bits). The WT1800E has a high-resolution 8.4-inch XGA display that allows up to six waveforms to be viewed in a split screen and displays up to 12 pages of different measurement parameters, which makes the WT1800E an ideal tool for efficiency testing in inverter-driven motors, in renewable energy technologies, and in traction applications (pumps, fans, and hybrids\/electric vehicles, etc.). The WT1800E can also display measurement results using vector format or trend graphs.<\/p>\n
<\/p>\n
The WT1800E can accurately measure voltage, current and frequency over a wide range. The basic power accuracy of the WT1800E can reach 1% ~ 110% of the selected voltage and current ranges, which corresponds to voltages from 15mV to 1100V rms, currents from 0.1mA to 5.5Arms (5A input unit), and currents from 10mA to 55A rms (50A input unit). Because the effects of low power factor errors are minimized (\u00b10.07% apparent power), the WT1800E ensures measurement accuracy even under large phase shift and high frequency conditions.<\/p>\n
Eliminating unnecessary range changes allows for faster signal tracking. With the WT1800E's range setting function, users can select the input range according to their specific use case, making it easier to reach the optimal range setting more quickly. This reduces time spent repeating production tests, such as the following settings that are often performed on production lines: set to OFF \u2192 100V \u2192 OFF, etc.<\/p>\n
Even with a data update period of only 50ms, the WT1800E can analyze up to 500 harmonics at a fundamental frequency of 50\/60Hz. In addition to the power parameters, the WT1800E offers two options for harmonic analysis.<\/p>\n

<\/div>\nThe WT1800E can measure energy trading in the power grid or battery charging and discharging. With the power integration function, the WT1800E can perform integration operations on positive and negative instantaneous values. The WT1800E can also measure total energy (Wh) and current (Ah) when load conditions vary widely, such as when a device transitions from standby to operating mode. When an input signal begins to fall out of the expected range, this function automatically adjusts the range and continues to perform the integration of the measured value.<\/p>\n
With the high-speed data acquisition function, the SigmaUrms, Sigma-Irms, and Sigma-P of DC signals and three-phase devices can be calculated every 5ms (external synchronization is set to OFF) or 1ms ~ 100ms (external synchronization is set to ON), depending on the frequency of the clock signal.<\/p>\n
The measurement period can be set manually or automatically. Nine data update cycles can be set between 50ms and 20s, and the data update rate can be changed automatically in response to fluctuations in the input frequency. This function is particularly useful when measuring equipment such as motors where the input signal frequency depends on the RPM.<\/p>\n

The WT1800E is equipped with a DC power supply for the AC\/DC current sensor CT series. The WT1800E can measure large currents by using a dedicated connection cable and shunt. By connecting the sensor in this way, the signal-to-noise ratio and immunity to interference can be improved.<\/p>\n
* To use a shunt, the WT1800E must be fitted with the \/EX option.<\/p>\n

<\/div>\nThe WT1800E not only measures electrical parameters, but with the optional motor evaluation function, it can also measure speed\/direction, torque, mechanical power, synchro-speed, slip, electrical angle, motor efficiency, and total system efficiency using the analog and pulse outputs of the torque speed sensor.<\/p>\n
