4.
Press the / keys to set the lower-limit confirmation voltage for Con-
tact Check.
Setting range: 0.20 to 5.00 kV (The value changes by 0.01 kV.)
To change the value by 0.1 kV, while holding down the SHIFT key, press /
keys.
If no lower-limit confirmation voltage for Contact Check is required, set it to
“OFF” using the ON/OFF key.
5.
Press the STOP key to complete the setting value.
The instrument reverts to the READY state.
To continue to the setting for the next item, press the key.
or
<Ex.> Set to 0.2 kV
.
STOP
• A value for the Contact Check upper-limit confirmation voltage which is lower
than the test voltage or a lower-limit voltage which is higher than the test volt-
age can be set but during this time, pressing the START key will not start the
test.
• When contact error is detected, the following errors will be displayed and the
test will terminate.
Err4
Contact error at the L side terminal
Err5 Test voltage setting lower than the lower-limit confirmation voltage
(wrong setting)
Err6 Output measurement voltage lower than the lower-limit confirmation
voltage (output abnormality)
Err7 Contact voltage(p. 22) lower than the lower-limit confirmation voltage
(measurement-type malfunction, contact error)
Err8 Pre-set voltage higher than the upper-limit confirmation voltage
(wrong setting)
Err9 Output voltage higher than the upper-limit confirmation voltage
(output-type or measurement-type malfunction)
* Test for Err6 and Err7 will not be carried out during ramp-up and ramp-
down.
* When FAIL hold is not set, an error message will appear for about 0.3 sec-
onds before returning to READY mode.
• To prevent ramp-up function and fluctuations in output voltage loads, carry out
the HIGH side terminal Contact Check only after the output voltage has
reached the test voltage value.
• As the upper-limit voltage for Contact Check is 5.00 kV, the judgment may be
inaccurate if the test voltage is set at 5.00 kV.
• As the lower-limit voltage for Contact Check is 0.20 kV, the judgment may be
inaccurate if the test voltage is set at 0.20 kV.
• Setting the voltages for the upper-limit and lower-limit Contact Check after tak-
ing into account the error margin of this instrument is recommended.
• The detected voltage for the Contact Check is the average detected value.
Therefore, if the waveform distortions are large, the margins of error from the
test voltage display will also be large.
