Electronic Counter<br />
This microprocessor controlled 8-digit counter is designed for the<br />
measurement time intervals, periods of oscillation, rpm, frequency<br />
and for pulse counting, etc. The unit of measure is displayed, and it<br />
is possible to divide the display into two by 4 digits.<br />
There are start/stop terminals for connecting microphones, photocell<br />
units, free fall equipment, etc.<br />
There is a connection terminal for GM counters for measuring<br />
radioactivity with selectable gate times.<br />
The counter is provided with an easily read LED display<br />
and a logically designed control panel. This makes the<br />
counter well-suited for demonstration experiments as well<br />
as for student laboratory exercises.<br />
The counter has memory for storing measured values as<br />
well as an RS232 serial output for computer interfacing.<br />
Time measurements can be made down to 1 ms, and<br />
frequencies up to 2 MHz can be measured.<br />

Photocell Unit<br />
The unit is suitable for the measurement of pendulum periods,<br />
time interval measurements for experiments on an air<br />
track, measurements of periods of rotation, etc. The unit<br />
consists of a photocell which is illuminated via a one millimeter<br />
aperture by light from a light emitting diode. A red LED<br />
(light emitting diode) is provided next to the light source to<br />
indicate that the light source is on. A green LED near the<br />
photocell indicates when the receiver is illuminated. The<br />
photocell unit is provided with two 6-pole DIN-connectors<br />
for connection to the electronic counter no. 2002.50 and<br />
serial connection to additional photocell units, when signals<br />
are to be sent to the same input connection on the counter.<br />
The unit is manufactured in rugged plastic with threads for<br />
horizontal or vertical mounting using the 10 mm diameter<br />
mounting rod provided. A connector cable for the electronic<br />
counter is also provided. The maximum distance between<br />
the photocell and the light source is 90 mm. Dimensions:<br />
B x H x D: 160 x 120 x 28 mm. Mass: 450 g.<br />
