Wavetek/Datron 9100 Multifunction Calibrator Unable to boot
« on: April 29, 2022, 12:00:09 am »
Hi,

I found myself a Wavetek 9100 today, it cannot boot. Upon powerup the instrument turns on with a blank white display and stays there. I managed to find the service manual and schematic on https://ko4bb.com/.

So far i have confirmed that PSU voltages are correct. So now I am having a look at the digital processor board. Will be probing the SRAM for activity later today. I also saw its using a Dallas 1287 RTC.

Is there be a possibility a dead battery in it cause the unit to not turn on?. Any wavetek 9100 user out there that can advice me on this?

Well, I wont say its a conventional service manual, not sure how to name it, but here is the link:

http://www.ko4bb.com/getsimple/index.php?id=manuals&dir=06_Misc_Test_Equipment/Datron/Datron_9100

Progress Update:
I have already unsoldered the Dallas chip and drill a hole to probe for the battery voltage, its dead.
Will solder an external battery shortly to see if it does something.

This manual is for 9100A, a Digital Tester. Maybe fluke got stuck with Datron's model number when they rebadged and  ended up getting stuck with 2 different instrument with similar model number?

Anyway, it was not the Dallas RTC, it was a long shot to begin with. Will continue my diagnose :)

Make sure that the dip switches 6, 7 and 8 in the back are set properly.
