4.9.4.2 OSC Test Procedure
1. Connect the DUT via correct connection.
When the title shows “MAIN MENU”, press the [TEST] Function Key to enter the TEST
function list. The title will display “TEST”. The display shows a list of STEPs which are set
and waiting for testing. The first field is STEP, the second field is test mode (OSC), the
third field is output voltage setting value, the fourth field is capacitance reading, and the
fifth field is test result.
2. Press the [STOP] key.
Press the [START] key to start the test. When this key is pressed, high voltage will be
output and the DANGER LED will be illuminated.
The test is now running with the maximum current / voltage output
applied to the DUT. Use extreme caution when working near the
analyzer or the DUT.
The third field will show the output voltage reading and the fourth will show the
capacitance reading. The timer counts down and displays on the status list.
3. PASS judgment
When all the tests have been completed and the fifth field test result shows PASS, then
the DUT is judged as GOOD and the output is stopped. The rear panel outputs the PASS
signal and the buzzer is turned ON.
4. FAIL judgment
If the measurement value is abnormal, the DUT is judged as FAIL and the output
is stopped. The rear panel outputs the FAIL signal and the buzzer is turned ON.
The analyzer stays on the function until the [STOP] key is pressed. The fifth field test
result shows FAIL.
Fail Status Description Table
Test result
Meaning
OPEN
Capacitance open circuit/reading is less than OPEN CHK setting.
SHORT
Capacitance short circuit/reading is greater than SHORT CHK setting.
Press the [STOP] key to stop the test output.
Note
The valid display digit of capacity in OSC mode is determined by the Cs current range.
Example:
Get Cs voltage 0.018kV, Get Cs capacitance value 17.4nF, current= 1.18mA -- at the
max current range.
Get Cs voltage 0.016kV, Get Cs capacitance value 17.42nF, current= 0.97mA -- at the
medium current range.
4.10 CALIBRATION Function
4.10.1 Enable Calibration
The instrument requires a minimum 30-minute warm up period prior to calibration. With the
instrument in standby status ([STOP] button previously pressed and no lights flashing),
remove the front panel calibration seal and push (using the tip of a small screwdriver) the
recessed switch through the hole in the front panel labeled Cal- Enable (to the in position).
