Verifying card installation
To verify that the card was properly installed:
1. If the instrument is controlled remotely (REM is displayed), press
EXIT
to switch control to local.
2. Press
SLOT
. The name and firmware version of the instrument is displayed.
3. Press
SLOT
again. The name and firmware version of the card in slot 1 is displayed.
4. If you have more than one card installed, continue to press
SLOT
until the slot you just installed is
displayed.
5. Confirm the name and firmware version.
6. Press
EXIT
to return to the operating display.
Connection safety
WARNING
Connection information for switching cards is intended for qualified service personnel. Do not
attempt to connect DUT or external circuitry to a switching card unless qualified to do so.
To prevent electric shock that could result in serious injury or death, comply with these
safety precautions:
Before making or breaking any connections to the switching card, make sure the
instrument is turned off and power is removed from all external circuitry.
Do not connect signals that will exceed the maximum specifications of any installed
switching card.
If both the rear analog backplane connector of the instrument and the switching card
terminals are connected at the same time, the test lead insulation must be rated to the highest
voltage that is connected. For example, if 300V is connected to the analog backplane
connector, the test lead insulation for the switching card must also be rated for 300V.
Dangerous arcs of an explosive nature in a high energy circuit can cause severe personal
injury or death. If the multimeter is connected to a high energy circuit when set to a current
range, low resistance range, or any other low impedance range, the circuit is virtually shorted.
Dangerous arcing can result (even when the multimeter is set to a voltage range) if the
minimum voltage spacing is reduced in the external connections. For details about how to
safely make high energy measurements, see High-energy circuit safety precautions.
As described in the International Electrotechnical Commission (IEC) Standard IEC 664, the
instrument is Installation Category I and must not be connected to mains.
