Re: Racal Dana 9916 Frequency Counter.
Good afternoon Gents, ok this is what i have found after printing off all your advice, i will address it to all rather than individuals, hope you dont mind.
IC1 pin 4 has 3.124v on it, so that i think is ok.
IC4 pin 5 has 10mhz, pin 22 has front panel input on it, gate pulses on pin19, 1mHz output on pin 6, 10kHz on pin 7, pins 15 - 18 showing data pulses, inputs on pins 8 - 10 change with position of front panel switch, nothing happens when i select lamp test, only LED,s lit are the decimal point ( alters in conjunction with front switch), top led showing mHz. so thats what i have found today. over to you gents,TQ
