DAC-HRE-1

DAC-HRE-1 can measure resistance of coil windings of motors, transformers, etc, under energizing AC
voltage. The direct reading of resistance is possible with 4-wire measurement method, and
temperature is calculated from measured resistance values and displayed.
(According to the testing standard JIS 5311)

DAC-HRT-1

DAC-HRT-1 can measure coil winding resistance of motors, transformers, etc, under energizing AC
voltage. The direct reading is possible with 4-wire measurement method, and temperature of
specimens is immediately calculated from measured resistance values and displayed. Ambient
temperature is automatically taken in by connecting an option sensor Model DAC-PT-100.
Thermal Printer and Selection Control Box DAC-SCB-2 are also available as optional items.
(According to the testing standard JIS 5311)

DAC-PT-100

When DAC-PT-100 is connected to DAC-HRT-1, it is automatically possible to import ambient temperatures.
DAC-PT-100 is useful to acquisition of temperatures from start to finish of test: initial temperatures, final temperatures, etc.

DAC-SCB-2

DAC-SCB-2 is a ten-channel switching device to connect with DAC-HRT-1 for switching 10 specimens and measuring their resistances.

DAC-HRI-3

DAC-HRI-3 is suitable for temperature tests of AC energized coils of EV (Electric Vehicle) motors, DC brushless motors, compressor motors, etc.
You can measure resistances of electrical equipment driving with an inverter power supply (PWM) under energized conditions.

A DC cut capacitor is necessary for using Hot Line Coil Resistance Measuring Equipment.
It blocks a testing DC current so as not to flow into a power supply driving a specimen.
You should select it in accordance with rated currents of specimens.

DAC-HRM-1/2

DAC-HRM-1/2 is a measuring instrument for shielding-layer resistance of power CVT cables, etc. under current-carrying conditions. Controlling shielding-layer resistance is useful to prevention and maintenance of cable deterioration. DAC-HRM-1/2 is the most suitable for power cable tests on site where it is not easy to break power supply, such as substations, power stations, plants, etc.

DAC-MRG-2

DAC-MRG-2 is designed to measure the low resistance of motors, transformers, power cables, and rotating machines, etc. Having a built-in current generator of 10A, the compact design with an aluminum trunk body facilitates transport as well as operation at on-site test. Introducing 4-wire measurement method, the meter provide a stable measurement of minimum resolution 0.1μΩ.

DAC-IVE-1

DAC-IVE-1 is accessory for connecting to DAC-MRG-2 that enables measurement of power cables with inductive voltages. It is possible to eliminate inductive voltages up to max 100V.

DAC-MR-50A/100A

DAC-MR-50A/100A can measure low contact resistance of switches, breakers, bus bars, bushing, etc,
with 4-wire measurement method. It has a built-in DC test source of 50A (or 100A), and the minimum
resolution is 0.1 μΩ.
