1) There are power sources for measurement and for charging and currents for
these voltage sources are “total current = current on measuring side + current on
charge side. The power source on the charge side can be set ON and OFF by a
setting.
2) Current setting errors are ±10%.

2.2.2 Voltage monitoring (Voltage check)
Voltage that is output is measured and is compared with the set voltage. Any deviation
from the specified range is indicated by flashing of the side mark.
2.2.3 Contact check function
Connection of a work is checked by measuring the capacity by an RF signal and contact
is checked by a difference between contact in an open circuit state.
Item Remarks
Capacity range allowed for contact
detection Minimum 0.5pF. More than 1/10 of
capacity on jig side.
Capacity offset range on jig side Max. 100pF (0.1pF resolution)
[Notice] This specification is for a measuring cable length of 1m. Readjustment is
needed if the length exceeds 1m. This function cannot be used if the measuring cable
length exceeds 2m.
