■ Accurate testing
based on standards Withstand voltage tests and insulation resistance tests based on various standards can be performed, accurate testing can be performed by pass / fail judgment function and timer function that compare by setting upper and lower limits of test.
In the withstand voltage test, the output voltage set by the voltage control knob is set to ± 5% of the reference voltage value (output voltage ≦ 1 kV: ± 50 V) The test can not be started until the voltage falls within the range. The voltage comparator function enables accurate testing.
■ Automatic test of insulation resistance test, withstand voltage test With the automatic test
mode, insulation resistance test and withstand voltage test can be conducted as a series of tests.
■ Fluorescent display tube The
fluorescent display tube is excellent in visibility and it is very easy to see, so you can check the test status and test results accurately and quickly.
■ Analog voltmeter (Withstand voltage test only) The
test voltage is digitally displayed on a fluorescent display tube, and it can be confirmed with an analog voltmeter.
■ Zero closing switch (withstanding voltage test only) It
controls the ON / OFF of the output voltage at the zero-crossing point and prevents damage to the EUT, even if the EUT is faulty.
■ Saving at the time of
test setting In order to quickly switch the test setting specified by the various standards and laws, the function to save the test setting value is provided and it is possible to save up to 10 setting values for each test mode I can do it. Also, since the set value just before shutting off the power is saved, the previous setting will be reproduced when the power is turned on.
■ EXT - I / O
EXT - I / O outputs signals according to the state of TWV - 552. You can also input start and stop signals.
■ Automatic testing and test results can be captured using the RS - 232C interface computer.
■ Status Out In
accordance with the status of TWV - 552, perform relay contact output from the terminal block on the rear panel.
