5.7.1 Multi-channel module
Multi-channel output is a built-in high voltage switching module attached to the lower part of the instrument.
Through the multi-channel output module, multiple points of the component to be tested can be connected with
multiple channels of the instrument at one time. During the test, the instrument controls the channel switch
according to the user-defined, and connects the corresponding port to the voltage resistant test end to realize
controllable test. The characteristic of this test is that user can realize the fast connection through the test
fixture, and it does not need to switch the interface during the test, so that the test is safe and reliable.
UT5320R-S4A/UT5320R-S8A has touch-inspecting function, its multi-channel test wires are double-wire ports.
Each channel’s port of the double-wire port has two lead outputs, of which the thicker plug is the high-voltage
lead during the test; the thinner plug is the current sampling lead during the test. A resistance of more than 1MΩ
is built-in between the two lines, which is used as the self-test standard of the port. In general, two lines must
be short-circuited as a port. If the test current passes through the built-in resistance, the built-in resistance
will be damaged and cause the test data current limiting error.
In contact-inspecting mode (CK function): the two test wires of the same port must be connected with the two
contacts of the same conductor of DUT respectively, and the instrument detects whether the port is conducted
and confirm whether the element is installed in place.

Notes
1. In the multi-channel status, the output port of the original hipot tester is still has the original function. It can
be used as a public end.
2. Output port connecting of the multi-channel is set by user-defined. Do not connect redundant high voltage
connection when in using, in order to prevent the dangerous.
