Waveforms are compared by the difference between a standard coil and a coil under test in terms of the number of coil turns, layer shorts, wire breakage, and differences in core material. The tester can also detect insulation defects by applying high impulse voltage and by corona discharge.
JTEKT Electronics Corporation took over the measuring instrument business from KOKUYO ELECTRIC CO. LTD (KDK) and handled the following products, but as demand decreased significantly, it has become difficult to maintain model numbers.
We apologize for the inconvenience, but we would like to inform you that orders for all measuring instruments ended on July 20, 2023, and these products have been already discontinued.
Additionally, due to this discontinuation, after-sales services (repairs, calibration, etc.) also ended on December 20, 2023.

We deeply apologize for the any inconvenience this may cause.
Specification
We are developing and marketing Coil Testers, KL Series to test electrical properties of coils in a nondestructive method.
【KL-901/902/903】
KL-901/902 can measure the number of winding, layer short and core material by comparing vibration waveforms of the applied voltage to the standard coil and the test coil. This instrument also can find an insulation failure by checking applying high pulse voltage and corona discharge.
【OK/NG judgment】
Area, difference and amount of corona are compared for judgment.
【Non-destructive test 】
Test is performed by applying impulse. Touch LCD screen Operation is very easy thanks to the touch screen. Memory 196 waveforms (Built-in memory), 700 waveforms (Compact flash memory)
【Switching Unit KLZ-08B and KLZ-09 】
KLZ-08B and KLZ-09 are circuit switching units suited to the coil tester KL-901 or KL-902 to test coils while switching one by one for OK/NG judgment.
[ Characteristics ]
1. These appliances are automatically controlled by external signals.
2. These appliances deal with various types of coils because of the setting of a test waveform for each circuit is available.
3. Work saving at the point of production and efficiency of the test can be promised.
