Help: Need Manual for Fluke 8060A DMM
Darren Harris
Is there a manual online that I can view/download?
I am supposed to be looking to measure +5V across some chips, but
don't know how to set the meter.
Thanks a lot.
The range buttons are as follows;
(Hz) (dB) -><-)))
1)2000mA 1000DC M(Upside down "U")
2)200mA 200 200k
3)20mA 20 20k
4)2mA 2 2k
5)200uA 200mV 200(Upside down "U")

Plug the probes into DC and COM.

operates like any other DMM so here is what you need to know:
Plug the black probe lead (negative) into COMMON. Plug the red probe lead
(positive) into DC Voltage.
Set Range to desired setting (if expecting 5V, then set to 20V scale #3 in
your list), but if voltage can be higher, then it can't hurt to start at a
higher setting and go lower if needed.
Measure voltage across the 2 points you want.
NOTE: Do not ever attempt to measure voltage with the red lead plugged in
either the amperage or resistance settings. Amperage will act as a short
and damage whatever you are measuring, and blow the fuse in the meter as
well. Resistance setting injects a voltage from the meter into the circuit
you are measuring and the meter can be damaged if the voltage it sees from
the circuit is higher than expected.
Good luck!

Thanks a lot.
I get "OL" on the screen when the 3rd button is depressed.
The probes are plugged into "common" which is imprinted in the black
box and "V (Omega sign) S" which is in the red box.
So I assmue that I power up the board and then and find two pins on
each chip that give me a reading?
I'm actually trying to trouble-shoot an arcade game PCB that is giving
rom errors. I was told to make sure it is getting the proper +5V at
the edge connector and also the chips at the far end of the board.
I played around with continuance(by depressing buttons 3 and 8)and now
know combination of pins on each chip on the board that gives me a
signal.
So I guess I will plug the board into the harness, and after powering
up, make sure +5V is present.
Any last words?
Thanks again.

to measure resistance and finding an open circuit (infinite).
Testing for the +5 VDC is certainly the first step. However, I'd really
suggest that if this test confirms +5, you find someone to help you do this
troubleshooting. Not even knowning how to operate a DMM is asking for a
disaster either to you or your equipment.

The Omega sign is RESISTANCE in OHMs. Plug the red probe into the VOLTAGE
jack. If you try to measure a live voltage in resistance mode, you can
damage the meter.
By the way, OL is OVERLOAD since the voltage being measured by the meter is
outside the range it expects to see. Resistance is actually measured by
injecting a voltage and measuring the voltage drop across a precision
resistor using ohm's law to then calculate the resistance from the voltage.
From what you have stated here in your two posts, I would recommend you not
continue to troubleshoot this and instead take it to someone who knows what
they are doing and can use test equipment..

lucky enough to find someone who knew anything about the PCB I'm
attempting get working(which is very, very unlikely), I'd have to run
back and forth with each and every issue when I needed something
measured.
I really need to find athe answers so I won't have to go through this,
and I'm way behind schedule. When I ask for answers at RGVAC, I
usually find no one who can help, or someone in particular telling me
my question is stupid.
I have several full sized coin-operated arcade video games and lots of
different game PCBs. And these machines are around 20 years old.
I picked up a DMM so I wouldn't have to depend on anyone for the
"easily" fixable problems. Or at least
I expect to eventually find the manual, but it really isn't clear on
these things anyway. The problem as usual is that there is no set
standard for terms, as far as what I read and what I'm told. So my
best shot is to find someone with the exact same meter who can tell me
exactly what buttons to push. Then I can use that info the next time I
have to check for +5V.
As far as "Set to (3)", I assumed that meant to push in the third
button down.
As for "the 20 V scale", there is nothing on the meter that says 20 V.
And as for "set to DC", the 6th button down indicates that if it is
pushed in it is for AC and if it is left out, it is for DC.(I left it
out).
As for "Plug the probes into DC and COM", there is no "COM. So I
assume he meant "COMMON", which is says in a black box over one of the
second of the three inputs at the bottom of the meter. The first input
has a red letter "A" over it, and the third input(which I plugged the
second probe into) has an omega sign between the letters "V" and "S".
Thanks.

Doesn't anyone know what the safety margin or range is for chips that
are supposed to register +5V?
(I guess that amperage and resistance are next).
Thanks a lot.

The operating voltage for TTL (and most other +5V ICs)
is 5V +/-5%, i.e. 4.75-5.25V.
The absolute maximum is usually -0.6 - +7VDC.

well....

But I think I figured it out anyway.

And you're running an Apple II? :)
Come on, much of the info on the Web is in PDF format and the reader is free.

You wouldn't believe the massive problems I've had over the last three
years.
If you go to "comp.os.ms-windows.misc" and check the title "@#$%!
Windows 98" which is my last post, you'd get a small sample of what
I'm talking about.

By the way, soes anyone know what would happen if someone by accident
sent, I don't know, let's say +12V where +5V was suppose to go? Hehe.
