Preface
Outline of the TOS7200
The TOS7200 is an insulation resistance tester that is available in a wide range of electric and
electronic components and equipment, and allows any test voltage to be set. Because it
features the window comparator and timer function, the tester is capable of efficiently
conducting insulation resistance tests based on various safety standards. Moreover, with the
panel memory, which can be recalled externally and the RS232C interface provided as
standard equipment, the tester can flexibly handle automated systems.
Features
Arbitrary setting of the output voltage
The output voltage may be set to between 25 V and 1000 V. Thus, insulation resistance
tests can be conducted on a wide range of electric and electronic components and
equipment.
Equipped with a discharge function
The tester features a discharge function, which discharges the electric charge in the device
under test (DUT.) This allows tests to be conducted more safely.
Equipped with a window comparator
The tester has adopted a window comparator system capable of making judgments on
both the upper and lower limits. This prevents non-contact-caused judgment errors and
other errors.
Equipped with a timer function
The tester features a timer function that allows the test time to be set. It also enables
setting of the wait time, allowing more secure measurements and evaluation.
