EXTRN: Selects a CMOS logic-level signal to be used as trigger, sup-
plied to the trigger input on the side of the unit.
TRG TIME: Can be set from 00 h 00 m to 23 h 59 m in 1 minute steps.

in memory.
0: DEFAULT Unit is reset to default measurement parameters when turned
off (except for SAVE, ERASE).
1: P_ON Measurement parameters are stored when unit is turned off and
reestablished when next turned on (except for SAVE,
