(2) Setting range 0.3 to 999sec: When the setting time is up then end the pause mode.
Open/Short Circuit Detection Mode (OSC)
OPEN CHK : Set the judgment test result to open condition (compare the test reading with
the read standard capacitance value [Cs]).
SHORT CHK : Set the judgment test result to short condition (compare the test reading with
the read standard capacitance value [Cs]).
CHNL (H-L)
: The setting is the same as AC/DC CHANNEL.
4.9 How to Process Test
4.9.1 Offset Value Calibration of Test Cable / Fixture
1. Ground test adaptable test cable plug in (+) and (-) terminals of DRIVE and SENSE. And
then makes test cable short-circuit (be sure under grounding test status now). Press the
[OFFSET] Function Key. The display will show the “MESSAGE” window.
2. After pressing the [START] key, the title will show “GET OFFSET TEST”.
3. The DANGER LED on the front panel turns ON. Current is output for five seconds (when
the TEST TIME is set to CONTINUE). The analyzer starts to measure the resistance of
the test cable and shows its value on the display. It is then stored in the memory.
4. When the test time ends, [OFFSET] is highlighted.
5. Press the [START] again and if the line resistance of measured test cable is 0 ~ 0.1mΩ, it
means line resistance of test cable had been deducted.
4.9.2 Standard Capacitance Value (GET Cs) Description
1. Before starting an open/short circuit detection mode (OSC Mode) test or changing the
capacitance under test, acquire the standard capacitance value (GET Cs).
2. Before reading the standard capacitance value (GET Cs), press the [OFFSET] Function
Key to do the OFFSET elimination. Do an OFFSET elimination when changing wires or
fixtures to ensure the accuracy of the testing.
3. Before reading the standard capacitance value (GET Cs), use the standard capacitance
sample in testing as the DUT. Press the [GET Cs] Function Key to read the standard
capacitance value for the standard value in testing.
4. When running an open/short circuit detection mode (OSC Mode) test, the OPEN/SHORT
test pass or fail condition is based on the GET Cs reading.
4.9.3 DUT Connecting Methods
Ground Resistance Test Mode (GB)
Ensure there is no output current and the DANGER LED is OFF. Attach the test cables to the
terminals using a box spanner and then connect the test cables to the DUT.
Ensure the ground cable has been tightened with a box spanner
Withstand Voltage / Insulation Resistance Test Mode (AC / DC / IR / OSC)
Ensure there is no output voltage and the DANGER LED is OFF. Connect the black ground
