The following table describes the Switch and Universal Machine (UM) settings available in the ATP Settings dialog box:
Switch study:
Statistic study: Study with statistic switches. Specify the number of simulation Num>0.
Systematic study: Study with systematic switches. Specify the number of simulation Num>0.
ATPDraw sets the correct sign of NENERG.
Switch controls:
Option 
Description 
ISW 
If 1, printout of all variable switch closing/opening time to LUNIT6. If 0 (zero), no printout. 
ITEST

Extra random delay using DEGMIN, DEGMAX and STATFR in STARTUP. Possible values are: 0: Extra random delay for all switches. 1: No random delay. 2: Extra random time delay added to all closing switches. 3: Extra random time delay added to all opening switches. 
IDIST 
Select probability distribution of switch. A value of 0 (zero) means Gaussian distribution and a value of 1 uniform distribution. 
IMAX 
If 1, printout of extrema to LUNIT6 for every energization. If 0 (zero), no such printout. 
IDICE 
Use of standard random generator. A value of 0 (zero) implies computerdependent random generator and a value of 1 standard random generator. 
KSTOUT 
Extra printed (LUNIT6) output for each energization. Output of timestep loop and variable extrema (if Extremal values checked). If 0 (zero), extra printed output. If 1, no such output. 
NSEED

Repeatable Monte Carlo simulations. Possible values are: 0: Every simulation on the same data case will be different. 1: Same result each time the data case is run on the same computer. 
Universal machine controls:
Here the user can specify global data to be used with Universal electrical machines in ATP. The selections apply to all universal machines in a circuit.
Automatic or Manual initialization.
Manual: Terminal quantities of all machines must be specified.
Automatic: Initial conditions calculated by ATP. See section 9D1.5. in the ATP Rule Book for requirements.
Prediction or Compensation based interface.
Prediction: The machine does not appear to be a nonlinear element to the external network. The option is not available for single phase machines.
Compensation: The machine does appear to be a nonlinear element to the external network. Certain rules regarding connecting machines together must be followed. Inclusion of stub lines is often required.
SI or per unit quantities.
