Function keys (1+2)
Function keys are keys whose function depends on the menu and
operating state of the unit. The current function is displayed directly next to
the key in the field with a black background.
Fig. 22: Indication of the current functions of the function keys; here, on the left, the "mode"
function and on the right the "menu" function.
"Up" and "down" keys (3+4)
These keys are used to select the functions and values that are available in
the menu or to change the selected parameters.
In addition, these keys also control the indication of the measurement value
channels in the value windows. The "up" key is assigned to the left value
window, whereas the "down" key controls the right value window.
• For a selection, press the "up" or "down" key repeatedly until the
desired measurement value channel is indicated in the respective value
window.
