INVERTER HOT LINE COIL RESISTANCE METER – DAC-HRI-3

The Inverter Hot Line Coil Resistance Meter is a testing instrument for measuring hot-line coil resistance of a motor stator coil. Traditionally, the motor under test is temporarily de-energized to measure its coil resistance, which is then converted to the corresponding temperature. Hot-line resistance measurement using this instrument enables high-precision and highly-efficient measurement of coil resistance while the coil is being energized.
