Connecting a DUT
Floating
With the default setting, Low Force and Low Sense terminals are connected to the
chassis ground. However, they can be disconnected from the ground for floating
measurements.
To specify the low terminal status, perform the following procedure. Setting is not
saved. Turning off the instrument sets the status to the grounded.
1. Press the Config > Source > Connection function keys. This opens the Output
Connection dialog box.
2. Set the Low Terminal State on this dialog box. It must be FLOATING for the
floating status, or GROUNDED for the grounded status.
3. Press the OK softkey.
For the floating status, the following indicator appears on the status information
area. And then the Low Force and Low Sense terminals can be connected to the
maximum of
250 V.
Channel 1 floating status indicator:
Channel 2 floating status indicator:
Figure 3-4 Dual View, Floating Status for Channels 1 and 2
CAUTION Do not apply current to the chassis ground. Doing so will damage the B2900.
WARNING Potentially hazardous voltages of up to 250 V may be present at the Low
Force and Low Sense terminals. To
prevent electrical shock, use accessories
that comply with IEC 61010-2-031. The terminals and the extended conductors
must be isolated by using insulation caps, sleeves, etc.
