The System tab of the SCAMP Control Dialog allows users to set SCAMP system parameters and to view results. The System tab is shown below.
SCAMP’s gradient channel gains can be set by entering a value between 1 and 128 into the Gradient Gain box. This is applied to the Gradient Channel shown in the drop down box. SCAMP inplements gradient gains by the formula
Gain = 256/NGRAD
Where NGRAD is an integer between 2 and 255. Not all possible gradient gains can be implemented by this scheme. When focus shifts from the Gradient Gain edit box the SCAMP Control Dialog computes the closest NGRAD and then re-computes and re-displays the Gradient Gain.
Gradient Gains must be set in response to environmental conditions (see Velocity and Gradient Gain Adjustment section elsewhere in this manual). If at least one profile was uploaded from SCAMP at the start of the SCAMP Control Dialog session then clicking the Display button will produce a plot of the selected gradient channel from the most recently uploaded profile. If no profiles were uploaded this session then the Display button is inactive.
Velocity
SCAMP’s velocity must be set by ballasting in response to environmental conditions (see Velocity and Gradient Gain Adjustment section elsewhere in this manual). If at least one profile was uploaded from SCAMP at the start of the SCAMP Control Dialog session then clicking the Display button will produce a plot of the selected gradient channel from the most recently uploaded profile. If no profiles were uploaded this session then the Display button is inactive.
When the SCAMP Control Dialog begins its operation it reads SCAMP’s internal parameters. These include the battery voltage at the time SCAMP is connected to the USB port. The voltages read are displayed on the left side with progress bars on the right that give the approximate remaining life of each battery. The user should insure that sufficient battery life remains for the next profile or group of profiles. SCAMP will operate about 4 hours on a set of Duracell batteries. SCAMP will obtain about 1500 meters of data in 4 hours, not counting time spent awaiting a Starting Condition. See the Checking the Batteries section for instructions on replacing batteries.
