Operation
4.8 Conducting the Test
4.8.1 Connecting the UUT
First ensure there is no voltage output and the DANGER LED is off. Connect the low potential
test cable (black) to the Tester RTN/LOW terminal. Short-circuit the test cable and high
voltage output terminal and ensure there is no high voltage output. Next, plug in the high
voltage test cable (red or white) to high voltage output terminal. Then connect the low
potential test cable to UUT and the high potential test cable to UUT.
4.8.2 Procedure for AC/DC Test
1. Connect the UUT properly following the connection method.
2. In the power on screen shown below:
AC
Illustration:
TEST 1/2 means there are 2 test steps and it is running the 1
st
test step at present. AC
indicates the test mode. “Position 1” indicates the set voltage, “Position 2” is the high limit
set for current, while “Position 3” is the test result.
3. Press STOP to prepare for test. The status line shows “STANDBY”.
4. Press START to activate the test
When this key is pressed it starts to output voltage and the DANGER LED is on. The
status line shows a counter to count down. “Position 1” will show the output voltage value,
“Position 2” will show the current readings and “Position 3” will show the test result.
5. GOOD Judgment
When all tests are done and the results show PASS, the Tester will see the UUT as a
GOOD product and cutoff the output. The HANDLER interface outputs PASS signal and
the beeper acts at the same time.
6. NO GOOD Judgment
If the test value is abnormal, the Tester judges it as FAIL and cutoff the output
