42 V peak, or 60 V dc. These voltages pose a shock hazard.
•Ensure the Calibrator is in STANDBY by pressing the RESET
key before disconnecting test leads.
•Ensure the grounding conductor in the power cord is
properly connected to a protective ground. The output
terminals are clamped to the earth referenced chassis and
rely on the protective earth bond to limit accessible voltage
to the operator. Any disruption of the protective earth could
place lethal voltage onto the chassis of the Calibrator due to
abnormal output terminal configuration or mains transient
condition.
•Use only the replacement fuses specified by the manual.
•Do not position the Calibrator such that the power cord
cannot be accessed in the event of an emergency. In the
event that customer installation interferes with access to the

•Use only a power cord that is in good condition. Refer
power cord and connector changes to qualified service
personnel.
•Do not operate the Calibrator in an atmosphere of explosive
gases.
•Verify the voltage applied to the unit under test does not
exceed the insulation rating of the UUT and the
interconnecting cables.
•Do not remove the Calibrator cover without first
disconnecting the power cord.
•Do not operate the Calibrator without the cover properly
installed. Access procedures and the warnings for such
procedures are contained in the Service Manual. Service
procedures are for qualified service personnel only.
•Do not use the Calibrator if it appears damaged or operates
abnormally. Refer all questions of proper Calibrator
operation to qualified service personnel.
Caution
To avoid damage to the Calibrator, do not apply voltage in
excess of the marked rating to any terminal.
Operation Overview
The 5080A Calibrator may be operated at the front panel in the local mode, or remotely
using RS-232 or Ethernet ports. For remote operations, several software options are
available to integrate 5080A operation into a wide variety of calibration requirements.
Typical local operations include front panel connections to the Unit Under Test (UUT),
and then manual keystroke entries at the front panel to place the Calibrator in the desired
output mode. The front panel layout facilitates hand movements from left to right, and
multiply and divide keys make it easy to step up or down at the press of a single key. You
can also review 5080A Calibrator specifications at the push of two buttons. The backlit
liquid crystal display is easy to read from many different viewing angles and in different
lighting conditions, and the large, easy-to-read keys are color-coded and provide tactile
feedback.

[1] Duty Cycle: Currents <11 A may be provided continuously. For currents >11 A, the current may be provided 60-T-I minutes in any
60 minute period where T is the temperature in °C (room temperature is about 23 °C) and I is the output current in Amps. For
example, 17 A at 23 °C could be provided for 60-17-23 = 20 minutes each hour. When the 5080A is outputting currents between 5
and 11 amps for long periods, the internal self-heating reduces the duty cycle. Under those conditions, the allowable “on” time
indicated by the formula is achieved only after the 5080A is outputting currents <5 A for the “off” period first.
