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 230/235 are Volts, Millivolts, Ohms, RTDs, and
Thermocouples. 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 230 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
85 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 page 71. 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
