Menu Section
In addition to displaying status parameters on the two 5-segment LED
displays(bottom sections) of the instrument, the Menu (top section) section of
the Model 6100 front panel enables users to view/change many more
parameters including feedback sensor type, PID values, and Steinhart-Hart or
Callendar – van Dusen coefficients, for example. Prior error messages can be
viewed as well.
4.4.1
Control Knob
The control knob on the right side of the front panel is used to set the value of
parameters such as Laser diode current setpoint (Ild), TEC temperature
setpoint (Ts) etc. Users can select the parameter whose value needs to be
modified using the Setup/Enter and Cursor Arrow keys, and then modify the
values with the knob. Alternately, the parameters' values can be modified
with the Arrow keys.
The knob has an acceleration algorithm that causes the rate of change of value
to increase as the knob is turned faster. Turning slowly allows for a fine
adjustment at the smallest displayed decimal place.
4.4.2
Setup / Enter
The Setup/Enter key is used to (a) invoke the Setup screen, (b) accept
parameter change, or (c) enter a lower menu level, depending on the screen
displayed.
4.4.3
Esc
The Esc key is used to (a) cancel a parameter change or (b) back up one menu
level.
