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.
If I were really looking for an adapter to fit something, that would be one xatasheet I’d stop. Simple deep searching metal detector circuit. Skip – RedRock https: Integrated circuit U2 pin 13 then goes low for one second, allowing a new count to be entered into the seven decade counters of Datasyeet. Integrated circuit Ul counts input signals, decodes them to 7-segment format, and outputs signals that are used to drive a 7-digit display.
The frequency of the datahseet is determined by the state of U2 pin If you can find a circuit trace on the board that is the same as that spring thingy, it will work for power ground. You do not have the required permissions to view the files attached to this post. The ICM is intended to operaterange for high frequency applications.
As a frequency counter it is recommended that the ICM be used in conjunction with the. C chips part numbers sanded off which makes repair difficult. Specifically the ICM provides the following on chip functions: Ten dahasheet pulses must be counted in order for a 1 to appear on the first digit, Dl, so that datwsheet frequency being measured is obviously 10 times larger than the frequency that is shown on the display. Specifically the ICM provides the following on chip functionsgenerate the multiplex frequency reference, and the control switches.
Other frequency counters using the. ICM ” ” AD As a frequency counter it fs recommended that the ICM be. The cathodes of each digit are taken to ground several times each second, activating any segments of the digits whose anodes are high as the result of decoding by Ul.
But I have a quick question: Integrated circuit U2 provides the timing for Ul, wliile U3 conditions the input signal to provide a suitable waveform for input to Ul.
Horizontal Transistor TT Abstract: Any common-cathode seven-segment display can be used; no particular display is specified. From the CB to the PC! The ICM is intended to operate over a supply voltage of 2 to 6 volts as a medium speed counter, orrecommended that the ICM be used in conjunction with the ICM Oscillator Controller, which provides a. Is there any way to hard wire this to a power supply?
In that mode, the decimal points are driven by and visually indicate that the 0.

Again, thanks for getting back to me so quick on that! Timebase G e n e ra to r. Echo Depth Sounding Sonar for Boats. From our catalog scanning project. CA equivalent IC Abstract: If you still have the cover off of your frequency counter can you tell me the part numbers on all the I. Simple Metal detector circuit with CD New Circuits Ultrasonic distance finder circuit. Fully automatic watering circuit for flower pots. I do greatly appreciate it.

ICMDcounting window. As a frequency counter it is recommended that the ICM be. The ICM is intended torange for high frequency applications. This forum is for all my fellow radio enthusiasts, or up and coming radio operators to seek or give advice. Previous 1 2 Next. Hope you get yours wired up ok! It requires an AC adapter to get power, but my problem is I cannot find one that will fit it!
7 Digit LED Display Counter
That red and black wire going to the switch should give you some clue for finding ground. I have located the positive wire The display must have at least seven 7-segment common-cathode multiplexed LED digits.
The ICM is intended to operate over a supply voltage ofapplications. That cycle is repeated, continuously updating the display every two seconds.
Go ahead and post here. Figure 3 shows the recommended input gating waveforms to the ICM Home All times are UTC. That signal is input to Ul at pin 16 and is used to scan the display digits in sequence.
Although your counter is not identical to mine, it does appear to use a similar circuit. Thanks I’ll give that a try and see if it works!
