Page 7: Introduction
INTRODUCTION This manual is designed to familiarize you with the Berkeley Nucleonics Model 555 pulse generator. Rather than the usual array of knobs and switches, the 555 uses a menu-driven user interface with “on-line” help -- once you learn the basics of operating your 555, you may never need to refer to this manual again. -
Page 8: Safety Issues
Berkeley Nucleonics does not warrant the operation of this product to be uninterrupted or error free. This product is not intended for medical or life-support use, for the detonation of explosive devices, or for any other application that could cause bodily harm in the event of a product malfunction. - Page 9 6. Never work alone. Someone should always be nearby to render aid if neces- sary. Training in CPR first aid is highly recommended. 7.

Page 15: Selecting Menus
• Enter the RATE menu, by pressing the FUNCTION key and then the "4" key. Set the desired pulse period. Note that in general the pulse delay plus pulsewidth should be less than the period. • Press the RUN key. Selecting Menus Parameters are grouped in menus, selectable using the function keys. -
Page 16: Item Edit Mode
Item Edit Mode When the current item is non-numeric, the Up and Down arrow keys are used to select among different options for the parameter. The adjustment knob may also be used to change the selection. If the item is an on/off toggle, the Up arrow (CW adjustment knob) enables the item and the Down arrow (CCW adjustment knob) disables the item. -

BASIC OPERATION With the channels in the normal mode, operation of the unit is controlled by the system mode and the external trigger. The basic modes are as follows: Operational Modes w/o External Trigger Continuous RUN/STOP button starts and stops a continuous pulse stream at the rate specified by the RATE menu. - Page 26 Single Shot RUN/STOP button arms unit. Generates a pulse for every external trigger received. Press the RUN/STOP button a second time to disarm the instrument.
