Enhancing our capabilities with latest instrumentation

Trinity Hardware and Software engineers ensure that our products are designed to exacting specifications using the latest available platforms. We have recently procured an MTE source - Model PRS 400.3 with a basic accuracy of 0.02%. Trinity's latest Test Bench, is capable of calibrating revenue meters as per the relevant test points as specified in the IS13779 and IS14697, for meters of class 1.0s to class 0.2s.

With addition of this source, we now have the capability to calibrate and test meters for import/export in all four quadrants, meters with accuracy class 0.2 and also meters, which operate at 60.00 Hz, instead of 50.00 Hz.

Our sophisticated lab enables us to perform almost all the testing required for validation in house. This includes MTE PRS 400.3 & ZERA TPZ 308 from Germany, which we use for calibration & testing of our products.
