HP 3470A / 3472A Multimeter dead
Hello, My favorite piece of nostalgia suddenly stopped working. The +5V and other supplies are ok. The display is blank except for the decimal point. The clock is working but the IC it passes the signal to does nothing with it. I assume that it is a divider of some sort. It has proprietary Motorola number 1820 -0567 I know it is a long shot but maybe one of you know. -- Boris Mohar |

Did a Google on your HP number.....shows a cross ref to MC4024 with the
basic description DUAL VCO. Best of luck with your repair - Gord |

It never occurred to me that Google would have that indexed. Regards, Boris Mohar Got Knock? - see: Viatrack Printed Circuit Designs (among other things) http://www.viatrack.ca |
