Push the softkey below [Chrt Spd] to manually change the recorder speed. The current chart speed
will be flashing on the upper line of the display. Use the encoder wheel to change the speed to any
value between 1 and 125. Push the softkeys below [sec] or [min] to change the timebase between
mm/second and mm/minute.
•
Turn the encoder wheel until the "CHART SPEED" reads 5 mm/sec.
•
Press the softkey below "back" to accept this value. The DASH II will return to the Chart Speed
Menu.
•
Press the softkey below [Dlog Spd] to set the data logger speed. For this recording mode, the speed is
set in seconds/line or minutes/line, using the encoder wheel as above. This mode has speeds ranging
from 200msec/line to 999 min/line.
4. SETTING UP CHARTS AND GRIDS
The DASH II has four recording modes. You can select between two discrete grids of 40mm each, two
discrete grids of 50mm each, a single large grid of 100mm with overlapped waveforms or a numerical data
logger. You can also turn the grids on/off, select the major and minor division sizing, position the
waveform anywhere on the grid, suppress or enable the printing of waveforms and vary the waveform trace
thickness.
