cover closed

FEATURES

• Measures power transformers, VT/PTs and current
transformer CT turns ratios

• Displays turn ratio, excitation current, winding polarity and %
deviation from the nameplate values

• Universal voltage (90-240V supply, 50-60Hz) via external
smart/fast battery charger; complete charge in less than
4 hours

• Two internal NiMH batteries provide up to 10 hours of
continuous operation

• Tests performed by exciting the primary and reading the
secondary; provides safer conditions for the operator

• Display warns of incorrect lead connection, reverse polarity,
open and short circuits

• Easy connection and test setup; no calibration or
balancing required

• Large dual display with adjustable contrast ensures clearer
visibility in any lighting environment day or night

• Low battery indicator
