Logic Polarity for Main- and Delayed-
Trigger Outputs Negative TRUE. High to low transition indicates the trigger occurred.
Fuse Rating Either of two fuses1 may be used: a 0.25I × 1.25I (UL 198.6, 3AG): 6 A FAST, 250 V
or a 5 mm × 20 mm (IEC 127): 5 A (T), 250V.
1Each fuse type requires its own fuse cap.

Nonvolatile Memory1, 2Battery life ≥5 years
Floppy disk drive 3.5 inch, 720 K or 1.44 Mbyte, DOS 3.3-or-later compatible
Internal hard disk drive
(option HD and 2M available on the
TDS 500C and 700C)

1The times that reference waveforms, stored setups, and calibration constants are retained.
2Data is maintained by small lithium-thionyl-chloride batteries internal to the memory ICs. At the time of manufacture, no
special disposal requirements were in effect for these batteries as the amount of hazardous material contained was below
the regulated threshold. Consult your local waste disposal agency for proper disposal.
