PEL-60-60-10 - Physical Instruments

LOCAL SENSE CONFIGURATION
When the Electronic Load is strapped for local sensing, an unavoidable voltage drop is incurred in the load leads and
this adds to the load regulation. Hence, local sensing is usually used in applications where the lead lengths are
relatively short or load regulation is not critical. Local or remote sense can be set by pressing UTILITY key and
then ENTER key to enter Measure Sense option.
To meet safety requirement, load wire size should be large enough to carry electric current of the source to the
Electronic Load without overheating. Stranded, copper wires are recommended. The wires should be large enough
to limit the voltage drop to less than 1V per lead. Refer to Table 2.4 for proper wire size selection. Input wire
connections are made to the "+" and "-" terminals on the rear panel of the Load.

WARNING
JJJJJJ
To protect personnel against accidental contact with hazardous voltages, ensure that the load, including connections,
have no live parts, which are accessible. Also ensure that the insulation rating of the load wiring and circuitry is
greater than or equal to the maximum input voltage of the electronic load.
WARNING
Never touch the input terminal when your hands are wet. Dry your hands first before operate the instrument.
