The color display is divided into four areas. Most of the display is used to show

the waveforms and grids. The area above and below the waveform display is

used for text related to menu items. On the right of the display is the menu

display area. This menu display area uses the ten menu display keys immediately

to the right of the color display.

The color display is used for real-time as well as data capture viewing. When

you make your choices using the menu display keys, the bottom part of the

display reports your settings as well as highlights the active choice.

Because the Dash 16u is versatile, where many choices are available, an encoder

wheel is used to quickly move through the selections. An example is gain setup

where the wheel is used to select your range and offset. Also, the encoder wheel

is used for moving the cursors when reviewing data.

A full QWERTY alphanumeric keypad is used for chart annotation (upper and

lower case), user scaling (engineering units), and setting up the gain of the

channels (range and offset).

There are eight buttons for speed control. Four buttons give quick selection of

common speeds: [1], [5], [25], [50]. Three other buttons to select the rate:

[HR], [MIN], [SEC]. The last key is the [SPD] key used to adjust the paper

speed, data logger (numeric) speed, select internal or external motor source, the

speed of the display (normal or trend) and to adjust the chart speed (+/- 2%).

Eight keys, one for two channels. For example, the first amp key toggles

between amplifiers 1 & 9. Set full scale range, offset (zero offset) from the

center of the channel, ground or unground the channel, select peak-to-peak or

RMS, setup filter, assign engineering units. Selecting the amplifier type, setting

the attenuator range and calibration are here as well.

Used to start and stop the chart paper real-time recording.
