Operating the TMD
REC-4105 Rev L
The keys on the TMD front panel are soft touch keys on a flat panel.
The keys are used to set up and calibrate the TMD. Figure shows these
keys on the front panel.
The up and down SCROLL arrow keys move the scroll of display
"screens" up or down one screen at a time when the TMD is in
Setup/Calibrate mode.
In Run mode, the SCROLL keys scroll through the high-level menu
displays shown below:
COUNT
PSWD N
CALIB? N
SETUP? N
NO ERROR
When either end of a scroll is reached, scrolling ends. Scrolls do not
wrap.
The up and down VALUE arrow keys change the value of the displayed
variable when the TMD is in Setup/Calibrate mode. Pressing the up
arrow increases the value. Pressing the down arrow decreases the value.
Values increase or decrease only within the range for the individual
variable.
Changed values are not entered into memory until you press the ENTER
key, and they flash in the counter until you press it.
Changed values are not permanently stored in system memory until the
TMD is placed back into Run mode.
The ENTER key enters a changed variable into memory. If the VALUE
keys are used to change the displayed value but the ENTER key is not
pressed, the original value of the variable is retained in memory.
