The high-voltage scanner TOS9220/TOS9221 has a function that distributes the test voltage provided by the TOS9220/TOS9201 to multiple test points. Up to four channels can be used for outputs on this scanner. Each channel can be set to one of the three electric potential modes - HIGH, LOW, or OPEN. Operator can conduct AC/DC withstanding voltage and insulation resistance tests on any of the four test points. Furthermore, up to four scanners can be connected to the tester, allowing a maximum of 16 channels. The TOS9200 is equipped with a "contact check function" to check the contact between the output of each channel and a test point.
These features ensure highly reliable and labor-saving withstanding voltage and insulation resistance tests for electrical and electronic eqiupment with multiple test points.
On the TOS9200/TOS9201, you can select an electric potential mode for each channel - HIGH (high voltage side), LOW (low voltage side), and OPEN (open mode). The high-voltage scanner permits AC/DC withstanding voltage or insulation resistance tests on any of the four test points A to D. For instance, you can set CH1 (test point A) to HIGH, CH2 (test point B) to OPEN, and CH3 (test point C) CH4 (test point D) to LOW. To specify these settings, you can use the TOS9200/TOS9201 panel or the GPIB/RS-232C.
