in high voltage test circuit, when return current flowing through shell is larger than 0.6A, the
high voltage output will be cut off, thus there will be no shock current in high voltage to
protect the operator’s safety.

in withstanding voltage test.
■
Current correction function
AC withstanding test needs high sensitivity and voltage, the stray capacitance effects the
accuracy of current test.TH9201series has the current correction function to eliminate the
moving current.
■
Voltage hold function
In the process of judge, this function allows operator to hold the record of test voltage when
the judge result is outputted continuously. The voltage hold function can monitor the
breakdown voltage by combining with rising time control function.
■
Easy operation
TH9201series are quite easy to be operated. In the setup interface, the test condition is
listed. Set test condition, use direction key to select a topic from LCD display, then rotate
code switch. Shortcut key can select the set topic. After setting the data, it will back to test
interface to perform test.
■
50 test programmes, and each one includes 100 test items, so it can save 500 test
items totally.
It can edit 50 test programmes which corresponds to user’s different test items
；
the test
item is one of AC withstanding voltage test, DC withstanding voltage, insulation resistance
test, open and short judge. Each test condition is noninteractive; the memory can save
500 test steps, and if the stored item is so large that most data have to be transferred to
external memory.
