Overview

The TOS7200 is an insulation resistance tester available for a wide range of various electric and electronic components, as well as electric and electronic equipment. The output voltage can be set at desired value in the range of – 25V to -1,000V with a resolution of 1V. (conforms with the output characteristics of the JIS C 1302-2002).

As it is fitted with a window comparator and timer function, the tester is capable of efficiently conducting insulation resistance tests based on various safety standards. In addition, this product is equipped with panel memory as standard feature, which can be recalled by remote control, SIGNAL I/O connector, and the RS-232C interface for easy automatic testing system construction.

LOWER FAILIf a resistance value equal or less than the lower resistance is detected, the tester shuts off the output and returns a LOWER FAIL judgment. Note that no judgment is made within the judgment wait time (WAIT TIME) after the start of the test.FAIL LED lights.
LOWER LED lights.		ONOutputs a L FAIL signal
PASSIf no abnormality is found when the set test time has elapsed, the tester shuts off the output and returns a PASS judgment.PASS LED lights.ONOutputs a PASS signal
  • A PASS signal is output for approx. 200 ms. However, if the PASS HOLD function is set to “HOLD,” the signal is continuously output until a STOP signal is input.
  • An UPPER FAIL or LOWER FAIL signal is continuously output until a STOP signal is input.
  • The FAIL and PASS buzzer volumes are adjustable. However, they cannot be adjusted individually, as they are set in common.
Setting range for the upper reference value (UPPER)0.01 MΩ to 5000 MΩ [In the range of the maximum rated current or less]

Safety *1

Conforms to the requirements of the following standard.
EN 61010-1 (Class I*2 , Pollution degree 2*3 )

*1 Not applicable to custom order models. *2 This instrument is a Class I equipment. Be sure to ground the protective conductor terminal of the instrument. The safety of the instrument is not guaranteed unless the instrument is grounded properly. *3. Pollution is addition of foreign matter (solid, liquid or gaseous) that may produce a reduction of dielectric strength or surface resistivity. Pollution Degree 2 assumes that only non-conductive pollution will occur except for an occasional temporary conductivity caused by condensation
