The DPATT-3Bi instrument is indigenously designed and developed by UMA Electronics, to make the testing of Stabilisers, Transformers ,Motors and other Electrical Machines Simpler , Faster, Accurate and Reliable with its high performing DSP based circuitry and user friendly operational features. The high speed simultaneous sampling of all the channels using 24-bit ADC ensures True RMS measurement of the wide range of input voltage and input current. This instrument displays Voltage, Current, Frequency, Active Power and Power Factor, both phase wise and TotalAverage. The measurement is valid at all power factors and gives accurate results even in the presence of harmonics in the system. It has two displays, one is Blue moon display for simultaneous display of the related parameters and another is seven segment display for long distance view. The keys on the front panel provide navigation of different parameters as well as range selection and Hold facility.

Digital Phase Angle meter shows phase angle between any two phases of VoltageCurrent Phase of VoltageCurrent can be selected True rms readngs. Inbuilt Voltmeter, Display : 4½ Digit, 12.5mm Bright Red LED., Range : 600V.AC, Resolution : 0.1V, Inbuilt Amp Meter, Display : 4½ Digit, 12.5mm Bright Red LED., Range : 20 A.AC, Resolution : 0.001A, Phase Angle Meter (between any two phases of VoltageCurrent , or between the phases of VoltageCurrent).

We have designed Automatic Motor Testing System AMTS-3, to make your testing Simpler, Faster, Accurate and Organized.
