Item Description
The color touch-sensitive display shows the output amplitude, frequency, and other
active conditions and messages. The display provides controls not available with
the keys alone. The Calibrator interface is made up of multiple menus, described in
Chapter 4.
Numbered keys to enter the output amplitude, frequency, and other data such as
the time and date. To enter a value, push the digits of the output value, a multiplier
key (if necessary), and an output function key. Then push

activates the programmed output.
deactivates the programmed output. The output automatically changes to
STANDBY if:
• is pushed
• The output voltage is changed from <22 V to >22 V
• The output location changes
• The output function changes. An exception to this is that the output stays
operational when functions are changed between ac and dc voltage.
Multiplier keys to select output value multipliers. For example, if
is entered, the Calibrator output value is 33 mV. The multiplier keys are:
micro (10
-6
)
milli (10
-3
)
kilo (10
3
)
mega (10
6
)
Output function keys. The output functions are:
Decibels relative to 1 mW
Voltage
Current
Resistance
Frequency
When Hz is entered, the Calibrator automatically switches to ac. When a new
signed (+ or -) output value is entered without specifying Hz, the Calibrator
automatically switches back to dc.
Backspace (Bksp) key. As a new output value is entered, use this key to delete the
last key entry.
The CE (Clear Entry) key clears a value entry in progress.
The Reset key returns the Calibrator to its initial power-up state.
Power button. Push the lighted power button to turn on or off the Calibrator.
The ENTER key changes the output value just keyed in with the numerical,
multiplier, and output function keys explained above.
