2.1.2 Measuring voltage output
The output is determined by voltage and current of the power supply input from the rear
panel.
1) Complies with 2.5 “Specification for Dedicated Power Supply Unit PSU
- 8541” when
the dedicated power supply unit PSU - 8541 is used.
2) The screen for operation of the DSM8542 is programmed assuming PSU - 8541 will be
used.

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 (V.CHK ON display).
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.
Non-contact is indicated by flashing of the side mark (C.CHK ON display).
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.
