REMOTE SENSING

Remote voltage sensing is recommended for accurate voltage measurement,
whether you connect sensing leads to the load or directly to the output
terminals. This will provide the most accurate voltage readback and front panel
voltage meter display.

CAUTION!

If the power supply is operated with load power lines disconnected and sensing
line connected, internal power supply damage may occur. (Output current then
flows through sensing terminals.)

To use remote voltage sensing, connect the power supply as described below.
See Figure 3–7 for connection requirements.

Connect sensing leads from the load positive to J3-1 and the load negative to
J3-2. A shielded, twisted-pair, hookup wire is recommended to avoid potential
noise interference.
