Series 2400 SourceMeter® Quick Start Guide
Basic connections
WARNING
The SourceMeter uses safety jacks for signal connections. To avoid
electric shock:
•
Do not leave exposed connections.
•
Properly insulate all external circuits.
•
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. Connection of the SourceMeter Input/Output terminals,
to circuits higher than CAT I, can cause damage to the equipment
or expose the operator to hazardous voltages.
•
Hazardous voltages may be present on the output and guard
terminals. To prevent electrical shock that could cause injury or
death, NEVER make or break connections to the SourceMeter
while the unit is on. Power off the equipment from the front panel
or disconnect the main power cord from the rear of the
SourceMeter before handling cables connected to the outputs.
Putting the equipment into standby mode does not guarantee the
outputs are not powered if a hardware or software fault occurs.
The three basic connection configurations for the SourceMeter include 2-wire local sensing, 4-wire
remote sensing, and cable guard.
NOTE Connections and details for in-circuit ohms measurements (ohms
guard) are covered in the “Advanced operation” section of this guide.
Front/rear terminals selection
The input/output and sense terminals are accessible from both the front and rear panels, while the
guard terminals and chassis ground are only accessible from the rear panel. On the front panel,
press the FRONT/REAR key to toggle between front and rear. The REAR annunciator indicates
that the rear terminals are selected. With REAR off, the front terminals are selected.
2-wire connections
Connections for 2-wire local sensing are shown in Figure 3. The following menu sequence selects
2-wire local sensing:
Press CONFIG > select SOURCE V (or
