Risk of electric shock. The TOS9320 scanner supplies the 5.0 kVac, 7.2 kVdc, or higher voltage received from the TOS93 series tester to external devices. Handling the prod- uct improperly may lead to a fatal accident. To prevent accidents, strictly follow the precautions and always pay the utmost attention to safety concerns when you operate the product. -

EUT, the test leads, the test probes, and the areas near the output terminals. • After the output has been turned off, the TOS93 series tester’s internal discharge circuit goes into operation and discharges the output voltage. During testing and before this discharge completes, do not disconnect the tester from the EUT. -
Page 12: Malfunction Precautions
Immediately turn off the tester’s POWER switch, and disconnect the power cord from the outlet. Further, turn off the TOS9320 scanners’ POWER switches, disconnect the power cords, stop using the system immediately, and contact your Kikusui agent or distributor. Emergency measures There are two actions that you must carry out if, due to a malfunction in the test system or the EUT, there is a possibility of an emergency occurring such as electric shock or damage to the EUT. -
Page 13: Installation
If the supplied power cord cannot be used because the rated voltage or the plug shape is incompatible, have a qualified engineer replace it with an appropriate power cord that is 3 m or less in length. If obtaining a power cord is difficult, contact your Kikusui agent or dis- tributor. -
Page 14: Checking Whether The Power Is On Or Off
Installation Checking Whether the Power Is On or Off Follow the procedure below when turning on or off each device in a system in which a TOS9320 scanner is connected. Turning the power on Turn on ( ) the POWER switch on the tester. POWER switch Turn on ( ) the POWER switch on the TOS9320 scanner. -
Page 15: Connecting To A Tos93 Series Tester
Up to four TOS9320 scanners can be connected to a TOS93 series tester. The TOS9320 scanner is an option for the TOS93 series tester, but by using the CONTROLLER INTER- FACE connector, you can also control the scanner from an external device such as a Kikusui TOS5300 series withstanding voltage and insulation resistance tester 25). - Page 16 (for example, the tester assigns channels 1 to 4 to the TOS9320 scanner that it is directly connected to). The following table shows the mapping of the channel numbers as seen from the TOS93 series tester and the channel numbers of each scanner.

Installation | Connecting to a TOS93 Series Tester Connecting to a TOS93 series tester As an example, this section provides the connection diagram and procedure for connecting three TOS9320 scanners to a TOS93 series tester. Risk of electric shock. Connect the cables securely. If cable connections are incom- plete, the scanner chassis or the entire EUT may be charged to a high voltage. - Page 18 (p. 17). • If you remove or insert an interface cable while the POWER switch on the TOS93 series tester is on, the tester’s protection function is activated. The display will show the word “SCANNER.” To release the protection, press STOP.

- Page 21 If you turn on the contact check function and press START on the TOS93 series tester, a contact check is performed before starting the test. The TOS93 series tester checks the continuity between the test leads and the EUT by turning on both relays x and y in the TOS9320 scanner for channels set to high or low, applying about 2 Vdc, and measuring the current.

Questions and answers
Does the scaneer needs to be calibration?
Yes, the Kikusui TOS93 series scanner requires calibration. You can set a calibration period from 1 to 24 months or set it to "Infinity" to stop monitoring. When the calibration period elapses, it can either trigger a protection mode or show a warning depending on the Protection setting.
