Figure 1 is typical of the main display for all operating modes. It
shows the present measurement or output value. The individual
operating modes are described below.
Use the MENU/EXIT key to display the main menu described in
section 3 to select the primary operating mode of the calibrator, to
access the calibrator setup functions, or to enter HART mode.
In output mode:
• Press the knob to move the decade cursor.
• Rotate the knob to increment or decrement the output in steps
indicated by the selected decade.
• Use the 3 percent keys to directly set the output to preset
values.
• Use the step/ramp key to select and stop these advanced
modes which are described in section 5.1.
