A Variety of Display Formats

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.

Increased Assured-Accuracy Range

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 with integration power measurement the voltage and current ranges are fixed, 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.
