Panel Description
(1) Please press F1 OFFSET to offset, it is necessary to offset wire or fixture at
each time change to ensure the accuracy of the test.
(2) When test or change a new capacitance DUT, the testing capacitance standard
sample as DUT. Press F2 GET Cs to read the standard capacitance value for testing.
(3) Please press F4 MORE.. key again to switch the menu which be displayed to standby.
(4) Press START key to begin the test. It will begin to output the voltage. The
DANGER indicator lights up and the “Status Line” shows “UNDER TEST” to warn
you that it is in test state and there is voltage output. "Line 1" will show the voltage
output reading, "Line 2" will show the reading of capacitance, and "Line 3" performs
timing and countdown work.
Note
When OSC Mode is testing, Get Cs current range at this time decides
the display of capacity effective digit.
Example: Get Cs voltage 0.018kV, Get Cs capacitance value 17.4nF, current=
1.18mA -- at the mass current range.
Get Cs voltage 0.016kV, Get Cs capacitance value 17.42nF, current=
0.97mA -- at the medium current range.
5. GOOD judgment
When all of test statuses have been tested and the result shows PASS, then the main
unit is judged as GOOD and cut off the output. The rear panel outputs PASS signal, the
buzzer functions simultaneously.
6. No good judgment
If the measurement value is abnormal, the main unit is judged as FAIL and stop to output
immediately. The rear panel outputs FAIL signal, the buzzer functions simultaneously.
Keep on function until STOP key of the main unit be pressed. The test result will show
no good status.
No good status
Test result Meaning
OPEN Capacitance open circuit/reading is fewer than OPEN CHK setting.
SHOP Capacitance short circuit/reading is larger than SHORT CHK setting.
Under any circumstances only need to press STOP key if you want to stop the test
output.
