Kikusui TOS 8850 Insulation Tester

Description

This equipment has been tested and is described as faulty/not working/for spares and repairs only. Please refer to the tests/remarks section below for details.

SERIAL NO: TOS 8850

MANUFACTURER DESCRIPTION:

Model T0S8850 W/I Auto Tester is a combination of an withstanding voltage tester and an insulation resistance tester, and it is capable of performing withstanding voltage test and insulation resistance test in one continuous process.

As for the withstanding voltage tester, the Tester can provide a maximum output voltage of 5 kV and an output wattage of 500 VA, and can be used for withstanding voltage test in compliance with JIS, UL, CSA, BS and other major electrical standards and ordinances. As for the insulation resistance tester, the Tester has two ranges of 500V/1000MQ and 1000V/2000MQ.

The Tester can perform a GO-NOGO judgement function when in either the with-standing voltage or insulation resistance test mode. A GO-NOGO judgement is with a window comparator type. When in withstanding voltage test, the Tester is capable of generating an NG judgement not only when the detected leakage current is greater than the high limit reference value preset on the front panel of the Tester but also when it is less than the low limit reference value (which is continuously adjustable down to one-half of the high limit reference value), thereby contributing to make GO-NOGO judgement including test of open circuiting of leadwires and imperfect contacting of connections.

The Tester is incorporated with a function to deliver signals representing theresult of GO-NOGO judgement and the state of the Tester, and a remote control function. The signals namely are TEST ON, GOOD, READY, and NG alarm (contact signals). The Tester is incorporated also with a remote control function for test set/reset. These features can be utilized for automatic test with labor economization.

Its sequence circuit is designed with full attention to noise to prevent erroneous operation which could be caused by noise.

Although many safety features are incorporated in the Tester, a deadly accident may occur when the operator touches the device under test (D.U.T) or the probe.

Safety guards around D.U.T. should be considered for safe operation.

Also, other precaution, which deemed necessary for the tester and the devices, shall be maintained under positive control.
