Confirmation Voltage used for upper and lower-limits for Contact Check
Contact Check can be carried out by measuring the terminal voltage of the
tested object. When this function is pre-set, test abnormalities can be detected
whenever the output voltage deviates from the pre-set ranges. The setting for
the upper or lower limit voltage confirmation is the same as that used for the H
side terminal Contact Check, but setting either the upper limit or the lower limit
will also automatically allow for Contact Checks on the L side terminals.
By measuring the voltage on the H side terminals of the tested object, checks on
whether an accurate voltage is supplied to the test terminals or not (whether the
test lead is properly connected or not: Contact Check) can be carried out. When
a value outside the range of the pre-set terminal voltage is achieved, an error
number will show and the test will terminate.
When Contact Check Function is not in use, press the ON/OFF key to set to
"OFF".
4.1.5 Setting the Confirmation Voltage used for upper
and lower-limits for Contact Check
1.
Press the key to move the flashing cursor to the upper-limit confirma-
tion voltage for Contact Check.
2.
When measuring the insulation-resistance, the following values will
automatically be set when the upper-limit Contact Check voltage is set
to ON.
Test-voltage 500 V : Upper-limit voltage 600 V
Test-voltage 1000 V: Upper-limit voltage 1200 V
If no upper-limit confirmation voltage for Contact Check is required, set it to
“OFF” using the ON/OFF key.
