Warm-up Time
AT851 is ready to be used as soon as the power-up sequence has completed. However, to
achieve the accuracy rating, warm up the instrument for 30 minutes is necessary.

Wiring Considerations
WARNING
FIRE HAZARD
To satisfy safety requirements, load wires must be heavy enough to not overheated
while carrying the short-circuit output current of the device connects to AT851.
Input connections are made to the + and - binding posts on the front panel.
A major
consideration in making input connections is the wire size.
The minimum wire size required to prevent overheating may not be large enough to
maintain good regulation. Stranded, copper wires are recommended to use. The wires
should be large enough to limit the voltage drop no more than 0.5 V per lead.
