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 Total/Average. 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.
The functionality of the meter is further enhanced with PC interfacing facility through USB Port. The accompanying software is capable of Data Logging, Set Point Alarm, and viewing the Meter Variables in real time on computer using the GUI provided. The data can be saved in SD memory card which can have 10,000 test results.

Optional Feature: mini-printer with meter
Printer with meter, prints all pages with Serial Number. This printer does not require computer/laptop, and prints all parameters which you can see on the meter directly. Ideal for shop floor and factory environment, where user can print readings instead of noting them down. The printer is a thermal printer, and so does not require any ink/cartridge.Only Thermal paper, which is available commonly.

Printer is optional.
Please mention its requirement while ordering.
