Output Functions
Output functions are selected by pressing any of the function keys
while the calibrator is in output mode. Output functions available on
the Model 130/135 are Volts, Millivolts, Milliamps, and Frequency.
Output mode is selected by pressing the OUTPUT key. The calibrator
remains in output mode until the INPUT key is pressed. The cursor
position on the display provides an indication of input or output mode.
When the calibrator is in output mode, the cursor is displayed in the
rightmost column.
Output measurements are displayed on the right-hand side of the
display, with engineering units displayed on the top line and simulated
value on the bottom. The output value displayed is the actual value at
the output terminals, not simply the setpoint value.
Volts/Millivolts
To output Volts or Millivolts, press the V/mV key when the calibrator is
in the Output mode. Pressing the V/mV key will cause the display to
alternate between volts and millivolts. (Note: the 130 has separate V
and mV keys. Press V for Volts and mV for Millivolts).
The calibrator will prompt for the value desired. The calibrator will
automatically select the proper range for the value entered. See page
68 for a description of the ranges and resolutions.
Enter the desired voltage and press ENT. If an improper or out of range
value is entered, the calibrator will display an error message. Error
messages and their meanings are displayed on pages 57 and 58. If the
value is within the operating limits, the calibrator will set the output to
the requested value. The output display will show the actual output
