Hi Randy,

       After starting the computer and the AmaSeis program, click on Settings 
at the top left hand corner, click on Com Port and reset it if necessary.

       Click on Settings, click on Device, select the DATQ154 option and 
click OK.

       Click on Settings, short circuit the input to the DI-154RS (CH1 and 
Gnd), disconnecting / switching off your amplifier if necessary, click on Read 
Data Value and note the number. You do need to short circuit the ADC input 
terminals - it draws / gives out current.

       Click on Settings, click on Set zero level, delete the figure 
displayed (2048?), enter this figure and then click OK.

       My DI-154RS gives a zero at 32640 instead of 32768 - 2^15 - but for 
$39, who cares?

       Go to the other options in settings and enter any relevant data.

       Hope that this helps,

       Chris Chapman
