Calibrating Sets B0 at the end of calibration.
Settling Sets B1 at the end of the settling period.
Trigger layer Sets B5 when leaving the trigger layer.
Arm layer Sets B6 when leaving an arm layer.
Calculating Sets B9 at the end of a math calculation.
Idle Sets B10 when leaving the idle state.

Programming example 10 OUTPUT 716; “:stat:oper:ntr 1026; ntr?”
20 ENTER 716; A$
30 PRINT A$
40 END
Line 10 Sets Bits B1 and B10 of the NTR Operation Transition Filter, and then queries the
register.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays the decimal value that defines which bits in the register are set (1026).
