Dual Control Screen
The Calibrator should display a screen similar to the one shown below at power up when
the instrument is set-up utilizing independent test ports. When the system is configured
for the single test port option, then the instrument will always display a single channel
screen. This is because the system automatically switches between the two channels
when controlling in this configuration. This is the top of the menu tree. The rotary knob
may be used to highlight a set-point to edit. Then enter the new value using the keypad.
This will show up in the scratch pad on the lower portion of the screen. Press the Enter
key and the highlighted value will be updated.
