To calculate the ratios, the DTR8510 uses the IEEE C57.12-90-2006 measurement method.
To ensure greater user safety, the tests are performed by excitation of the primary and measurement on the secondary.

Advantages of the DTR8510:
½ NiMH battery life of up to 10 hours
½ Automatic calibration and balancing ½ saves considerable time ½ No adjustments required.
½ Low-voltage test ½ Prevents errors due to saturation of the CTs when they are tested at high voltages.
½ Digital display ½ display of ratios, winding direction - % deviation in relation to rated values - excitation current. The bargraph indicates the progression of auto-calibration and measurement.
½ Degauss function to eliminate magnetic effects and improve accuracy
