Connection Methods
2.2 Connecting Measurement Probes and Test
Fixtures
• Do not apply any voltage to the measurement jacks. Doing so may damage the unit.
• When disconnecting the BNC connector, be sure to release the lock before pulling off the
connector. Forcibly pulling the connector without releasing the lock, or pulling on the cable,
can damage the connector.
• We recommend using optional Hioki fix-
tures.
• Use the GUARD jack only for the High-
Resistance Measurements shield, and
avoid more than a 10 mA current flow.
This jack is not for guarding the network
resistance measurements.
