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.
Current sensor input range (same for 5 A and 50 A input elements; standard)
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:
Evaluation of characteristics at motor startup including torque and rpms (requires the optional motor evaluation function)
Measurement of rapidly fluctuating secondary voltage and lamp current when a light is turned on.
