Revision A
WARNING- HIGH ENERGY AND HIGH VOLTAGE
Exercise caution when using and servicing a power supply. High energy levels
can be stored at the output voltage terminals on a power supply in normal
operation. In addition, potentially lethal voltages exist in the primary circuit and
on the output and sense connectors of a power supply with a rated output
greater than 40 V. Filter capacitors store potentially dangerous energy for some
time after power is removed.
Follow established antistatic procedures.
Work at a bench with adequate room and support for the test unit and for all

equipment required.

To reduce shock hazard, use only an insulated, straight-bladed screwdriver when
calibrating trim potentiometers.
NEVER test these units alone. Ensure that someone is present who can help
should an accident occur.
5-1/2 digit true RMS voltmeters (DVMs) (±0.05% accuracy) with test leads.
Current shunt 1 mV/amp (±0.25%) and connecting wire. Current rating for the
DC shunt and connecting wire must be at least 10% greater than the power
supply's output current rating. See also
for Wiring".
Non-conducting, straight-bladed screwdriver.
