Local Sense
Local sense is only recommended when the voltage drop is of no
consequence or for load-current applications. By default, the sense
plug is already configured to local sensing.

Remote Sense
Remote sense is used to compensate for the voltage drop seen across
load cables due to the resistance inherent in the load cables. The
remote sense terminals are connected to the load terminals of the
DUT to determine the voltage drop across the load cables.
Model Range Maximum Compensation Voltage (V)
PHU 80-170/ 80-340/ 80-510 4 V
PHU 200-70/ 200-140/ 200-210 10 V
PHU 500-30/ 500-60/ 500-90 25 V
PHU 750-20/ 750-40/ 750-60 37.5 V
PHU 1000-15/ 1000-30/ 1000-45 50 V
PHU 1500-10/ 1500-20/ 1500-30 75 V
Load cables should be chosen with a voltage drop less than the
compensation voltage.
Do NOT bundle the sense wire-pair together with the load wires;
keep the load wires and sense wires separate. Keep the sense wire-
pair as short as possible and twist or bundle it to reduce lead
inductance and noise pickup.
