Introduction

The PASCO Time Pulse Accessory is designed to activate the ME-9491Fan

Accessory or the ME-9781 Variable Speed Motorized Cart for a selectable

period of time. Since the Fan Accessory produces an approximately con-

stant force, the Time Pulse Accessory can be used to perform motion stud-

ies of a cart under conditions of constant acceleration for a fixed time

interval. When used with the Variable Speed Motorized Car, the same kind

of studies can be done for constant speed conditions.

Controls

The Time Pulse Accessory has three controls: START, VARIABLE, and

TIME. The TIME control switch is a four-position switch. The selected

time interval is indicated by a small number visible in the “V”-shaped

notch on the switch. The “0” position is a 1 second interval, the “1” posi-

tion is a 2 second interval, “2” position is a 4 second interval, and the “3”

position makes the VARIABLE control knob active.

VARIABLE Control Knob

The VARIABLE control knob is a potentiometer that adjusts the time interval from less than one second to about seven seconds.

Turn the VARIABLE control knob to MIN for the shortest time interval (less than one second) and turn the knob to MAX for the

longest time interval. The position of the knob is approximately proportional to the time interval. For example, when the knob is

halfway between MIN and MAX, the time interval is approximately 3.5 seconds.
