2.4 Connection of the Input Unit
────────────────────────────────────────────────────
2.4.1 8936/ 8938/ 8946 ANALOG UNITs
WARNING
Never connect the probe to the 8841/42 while the probe is already
connected to the measurement object. Otherwise there is a risk of
electric shock.
Use only the specified connection cables.
An insulated BNC connector is used for the specified connection
cables to prevent electric shock. If a metal BNC connector is used,
electric shock may result, as the input L-terminal and the metal part
of the BNC connector will have the same potential.
CAUTION
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.

2.4 Connection of the Input Unit
Use only the specified connection cables. Using a non-specified cable may
result in incorrect measurements due to poor connection or other reasons.
In addition, the BNC connector may be damaged.
For safety reasons, only use the optional 9197, 9198, or 9217
CONNECTION CORD for connection to the analog input units.
(For the 8946, use the 9198 CONNECTION CORD.)
Connecting to the main unit
1. Align the BNC connector with the guide groove of the unit input
connector, and turn clockwise while pressing in to lock the connector.
2. To remove from the unit, turn the BNC connector counterclockwise to
release the lock, then pull it.
Setting channels of the 8946 4 ch ANALOG UNIT (8841 only)
When the 8946 4-channel analog unit is used, input channels 1 to 4 are not
set in this customary sequence on the 8841. The slot position at which the
8946 is mounted determines the set input channel (see the illustration
below). To confirm the position of the setting channels, see Section 9.6.
