Higher test accuracy
ST9201 series has a digital voltage display, in withstanding voltage test, the
accuracy is ±(1% of r5V), in insulation resistance test, it is ±(1% of
r2V). The digital display of test current is ±(1% of r5 digits)
in withstanding voltage test.
■
Current correction function
AC withstanding test needs high sensitivity and voltage, the stray capacitance
affects the accuracy of current test. ST9201 series has the current correction
function to eliminate the moving current.
■
Easy operation
ST9201 series are quite easy to be operated. In the setup interface, the test
condition is listed. Set test condition, use direction keys to select a topic from
the 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 programs, and each one includes 100 test items, so it can
save 500 test items totally.
It can edit 50 test programs 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, U-disk is
available.
