Front-Panel Operation
Connect the Calibrator to a UUT

4-9
•
A p-p voltage output (square wave, triangle wave, or truncated sine wave) changes to
rms voltage output
≥
33 V (sine wave). For example, if a p-p output of 40 V is
changed to rms output of 40 V by a change to the wave form with the WAVE
softkey, the Calibrator goes to the standby mode.
•
The output location for current is changed from AUX to 20 A, or from 20 A to
AUX .
•
An overload condition occurs.

Warning
To prevent possible electrical shock, fire, or personal injury, do
not make connections to the output terminals when voltage is
present. Standby mode is not sufficient to prevent shock
hazard because

could be pushed accidently. Push

and make sure that the Calibrator is in standby before you
make connections to the output terminals.
The NORMAL (HI and LO) outputs are used to source voltages, resistances, capacitance,
and simulate resistance temperature detector (RTD) outputs. The LO terminal connects to
the analog signal ground in the guard shield. This signal line can or cannot be connected
to the chassis ground. This depends on how

is set. See “When to Use EARTH” in
this chapter for more about these internal connections.
The AUX (HI and LO) outputs source current and low voltages in the dual voltage
function. These outputs are also used for four-wire or remote sensing in the resistance,
capacitance, and RTD functions.
When an oscilloscope calibration option is installed, the SCOPE OUT BNC connectors
and TRIG give signals for oscilloscope calibration.
Use the TC socket to measure thermocouples and to supply simulated thermocouple
outputs.

Warning
To prevent possible electrical shock, fire, or personal injury:
•
Do not use test leads if they are damaged. Examine the test
leads for damaged insulation, exposed metal, or if the wear
indicator shows. Check test lead continuity.
•
Use only cables with correct voltage ratings.
•
Connect the common test lead before the live test lead and
remove the live test lead before the common test lead.
•
Use only the mains power cord and connector approved for
the voltage and plug configuration in your country and rated
for the Product.
