If the test value is detected abnormal, it is judged as fail and immediately cuts off the output. The
rear panel gives a fail signal and the buzzer operates simultaneous, and it will continue until the
【
STOP
】
key is pressed. The test result in the lower right corner displays FAIL.
Explanation Table for Fail:
Displayed Test Result
Meaning
>High Limit
Test value is greater than the set high limit.
< Low Limit
Test value is smaller than the set low limit.
ARC FAIL
Current arc exceeds high limit.
GFI FAIL
Ground failure interrupt
SHORT FAIL
The instrument output current is greater than the internal set
current limit. This limit cannot be changed,
the AC test has a
short-circuit current of 200 mA and a DC test of 40 mA.
Table 4-8
In any case, if you want to abort the test output, just press the
【
STOP
】
key.
4.5.4.2 OSC Test Procedures
1.
Connect the DUT correctly according to the connecting method of the DUT.
Press the
〖
TEST
〗
key to enter the Test interface, at this time, the pending test steps that have been
set up are displayed, the small font shows the test steps, the test mode, and the open circuit judge
percentage and the short circuit judge percentage. The large font in the middle shows the set voltage,
capacitance value and time.
2.
Press the
【
STOP
】
key to prepare for the test.
Press the
【
START
】
key to start the test, when this key is pressed, there will be a high voltage
output, and the DANGER light will flash.
The first line of the large font shows the actual measured
high voltage output value, and the second line is the measured capacitance value, the third line is
the
corresponding
time, there is a message prompt in the lower left corner.
3.
Pass Judge
When all the test modes are done and the test result in the lower right corner displays PASS, it is
judged as pass,
and cut off the high voltage output, the rear panel also gives a pass signal, the
buzzer simultaneously acts.
4.
Failure Judge
If the test value is detected abnormal, it is judged as fail and immediately cuts off the output. The
rear panel gives a failure signal and the buzzer operates simultaneous, and this will continue until
the
【
STOP
】
key is pressed. The test result in the lower right corner displays FAIL.
Explanation Table for Fail
Displayed Test Result
Meaning
OPEN
Open capacitor, the percentage of capacitance test value and sampling
standard value is smaller than the set percentage of open circuit judge.
SHORT
Short capacitor, the percentage of capacitance test value and sampling
standard value is greater than the set percentage of short circuit judge.
