■ High-voltage scanner
The high-voltage scanner TOS9220/TOS9221 has a function to distribute a test volt-
age supplied by the tester among multiple test points.
• A single high-voltage scanner distributes an output to four channels. Each
channel can be set to a different electric-potential level – HIGH, LOW, or
OPEN. AC/DC testing and insulation resistance testing can be conducted at
any of four test points.
• Up to four scanners can be connected to one tester, enabling expansion to a
maximum of 16 channels.
• The contact between the output on each channel and a test point can be
checked (the contact check function is provided for the TOS9221 scanner
only).
These features ensure highly reliable, labor-saving withstanding voltage and insula-
tion resistance tests on electric and electronic devices and components having multi-
ple test points.
• This high-voltage scanner is designed for a maximum working voltage of 5
kVAC/6 kVDC. It is dangerous to apply a voltage exceeding this level. Be
sure to use this scanner at a test voltage below the maximum working volt-
age.
