5. SETTING UP ZERO AND GAIN

The [CH1] and [CH2] keys (Channel 1 and Channel 2) are used to set a variety of parameters, including:

turning each channel on/off, selecting a voltage sensitivity for a channel, selecting a location for the input

zero position, suppressing a DC component of the waveform input, choosing between RMS and peak to

peak recording modes, grounding the input signal, selecting between standard voltage inputs and bridge

inputs, selecting filters and calibrating each channel.

•

Press the [CH1] key. The Channel 1 menu will appear. Note: The channel 2 menus and operations are

identical to those of Channel 1.

CHANNEL 1 MENU

1 - DC

Sens

The first line shows the channel status. In the above example, channel 1 is in DC mode at a sensitivity of

5.0 volts full scale.

SENSITIVITY In the new generation DASH II recorder, voltage is expressed in reference to full scale.

Since signal size is independent of grid size, a finer or coarser view of the signal data can be obtained by

adjusting channel sensitivity.
