QFL(ASH)/SETFLA(SH)/FL(ASH) - Pre-flash control

QFLASH prints out the currently selected pre-flash time, measured in arbitrary units of about 1 microsecond. SETFLASH sets up this time. The actual flash is performed automatically prior to a GLANCE or RUN, or on demand using the FLASH command.

This is not available for the RCA chip. For the GEC chip the default pre-flash time is 0 seconds.


QFLASH requires none. SETFLASH requires the pre-flash time. If omitted, it will be prompted for. FLASH requires none since it uses the time previously set up by SETFLASH.


Adam:> SETFLASH 10

Adam:> FLASH


SETFLASH does no more than set a microcode variable governing the flash period. It performs no flash. To disable pre-flash give a zero flash time.

If the preset FLASH time is 0. FLASH does nothing.

***For the JKT PREFLASHDEFAULT = 0 is the default, since it is not considered necessary for the GEC2 chip. (There is no preflash available with the RCA2 chip).
