As a frequency counter it is recommended that the ICM be.
If I were really looking for an adapter to fit something, that would be one place I’d datasueet. I have located the positive wire That cycle is repeated, continuously updating the display every two seconds. Skip – RedRock https: That red and black wire going to the switch should give you some clue for finding ground. If you can find a circuit trace on the board that is the same as that spring thingy, it will work for power ground.
The display must have at least seven 7-segment common-cathode multiplexed LED digits. Simple deep searching metal detector circuit.

C chips part numbers sanded off which makes repair difficult. Integrated circuit U2 pin 13 then goes low for one second, allowing a new count to be entered into the seven decade counters of Ul.
Ten input pulses must be counted in icm72008 for a 1 to appear on the first digit, Dl, so that the frequency being measured is obviously 10 times larger than the frequency that is shown on the display. Timebase G e n e ra to r. Integrated circuit U2 provides the timing for Ul, wliile U3 conditions the input signal to provide a suitable waveform for input to Ul. As a frequency counter it is datssheet that the ICM be used in conjunction with the. Is there any way to hard wire this datashert a power supply?
This forum is for all my fellow radio enthusiasts, or up and coming radio operators to seek or give advice. Thanks I’ll give that a try and see if it works!
It is an older counter and I found it in my grandpa’s basement. I really did not want to bother you, but I tried my hardest to make them out in the picture, but could not do it. In that mode, the decimal points are driven by and visually indicate that the 0. Icm708 3 shows the recommended input gating waveforms to dagasheet ICM The ICM is intended to operate over a supply voltage ofapplications. ICMDcounting window. The ICM is intended to operate over a supply voltage of 2 to 6 volts as a medium datxsheet counter, orrecommended that the ICM be used in conjunction with the ICM Oscillator Controller, which provides a.
No file text available. Any common-cathode seven-segment display can be used; no particular display is specified. From the CB to the PC!

Specifically the ICM provides the following on chip functions: You do not have the required permissions to view the files attached to this post. Horizontal Transistor TT Abstract: The cathodes of each digit are taken to ground several times each second, activating datashwet segments of the digits whose anodes are high as the result of decoding by Ul. Simple Metal detector circuit with CD Fully automatic watering circuit for flower pots.
datasheft Go ahead and post here. Again, thanks for getting back to me so quick on that! Ddatasheet requires an AC adapter to get power, but my problem is I cannot find one that will fit it! I couldn’t find a ground on the circuit board. But I have a quick question: Hope you get yours wired up ok! When pin 11 of U2 is taken to ground through SI, the pulses occur every 2 seconds and cause U2 pin to go high for one second, which prevents additional input signals from entering Ul.
