At least 288 intervals may be stored. Up to 707 unstable event values (see AutoHold) are automatically added to LOGGING memory for viewing only through optional PC software. Additional intervals will be logged up to 995 if the signal is stable.
Up to 100 readings may be saved by the user in a memory separate from LOGGING memory. These readings may be viewed using VIEW MEM.
