Remote command terminals selection
Use the :ROUTe:TERMinals (Section 18) command to select the front or rear
panel terminals via remote.
Test fixture output enable
A test fixture switch can be used with the SourceMeter to help protect the DUT.
The SourceMeter output will turn off when the lid of the test fixture is opened.
However, you must ALWAYS assume that power is present until you verify that
the SourceMeter output is off. See Section 13 for details.
Connections to DUT
The maximum allowable voltage differentials between terminals are labeled on
the SourceMeter. Figure 2-1 shows these voltage differentials for the various
SourceMeter models.
WARNING To prevent electric shock and/or damage to the SourceMeter,
DO NOT exceed the maximum allowable voltage differentials
shown in
Figure 2-1.
The front and rear terminals of the SourceMeters are rated for
connection to circuits rated Installation Category I only. Do not
connect the SourceMeter terminals to CAT II, CAT III, or CAT IV
circuits. Connections of the SourceMeter Input/Output termi
-
nals to circuits higher than CAT I can cause damage to the
equipment or expose the operator to hazardous voltages.
Common mode current limits — As shown in Figure 2-1, the maximum common
mode voltage is the voltage between INPUT/OUTPUT LO and chassis ground. In
order to prevent electric shock and/or damage to the SourceMeter, current from
an external common mode voltage source must be limited. Current limiting can be
accomplished with the use of a protective impedance or a fuse.
