Parameter
Sets the exponent leak range for Manual mode. Preceded by a two-character number
Acceptable values are 0 through -10.
Sets the ion value of the ion source. Preceded by a three-digit number of volts, in the range
200 to 350.
Sets the Range Stop exponent. Preceded by two or three characters -XX or -X.
Parameter
Initiates auto-ranging mode. Success is indicated by the normal ok response.
Initiates a Full or Fast calibration depending on system settings. The CPU software tunes,
then adjusts the gain so that the current helium signal causes the current leak rate
measurement to be the same as the most recently input using INIT-STDLEAK.
Subtracts 1 from the Manual Ranging leak rate exponent (making it more negative).
Success is indicated by the normal ok response. Does nothing in auto-ranging mode. Does
nothing upon reaching the most sensitive range.
Turns the Zero Enable function OFF.
Disables the active Applications Setup.
Turns the password function OFF.
