GER 1500 USER MANUAL

GER 1500 SPECTRORADIOMETER 5ROW 2Row 2 displays the parameter menu as well as some additional statusmessages.The parameter menu is scrolled by depressing the MENU button. Theparameters AVG, MEM, INSTP, TRG, and OPTIC can be adjusted.In addition to the parameters listed above, the status of the optional GPSdevice may also be displayed using the MENU button.Parameter Menu:MEM xxxAVG xINSTP mxMEM xxx is the memory slot that stores theacquisition. The allowable values are from 1 to471.AVG x is the averaging value. The allowablevalues are from 1 to 9. The number of detectorscans to be averaged is 2 (x-1) .In INSTP mx, the m represents the integrationmode and the x represents the integrationspeed.The normal mode of operation is Automatic.When m is represented by an “A”, this indicatesthat the integration speed is in Automatic Mode.To change to or from Automatic integrationmode, press “Menu” when in edit mode.When m is represented by a “blank space”, thisindicates that the integration is in manual modeand the user must properly adjust theintegration speed for the current lightconditions.The allowable values for x are from 1 to 6. Theshortest integration time is 5 milliseconds. Theapproximate integration time in milliseconds foreach value can be approximated by 2 (x-1) *5.TRG ccccThe “Trigger Switch” can be used to activatethe laser when depressed and/or initiate a scanwhen released. The trigger switch has thefollowing operational modes:BOTH – The trigger activates the laser whendepressed and begins the acquisition whenreleased.SCAN – The trigger does not activate the laserwhen depressed, but begins the acquisitionswhen released.LSR – The trigger activates the laser whendepressed, but does not begin an acquisitionwhen released.GER 1500 USER MANUAL, REVISION 3.7
