Greetings,

If you have the operator's, service, or calibration manuals for a Fluke
6071A 200kHz - 1040Mhz Synthesized Signal Generator. I could really use your
help. My unit appears to be broken; it has two flashing indicators, AMPL and
UNCAL, and there is no output coming from the unit. I have enough experience
with this unit to know it is not working correctly.

I have never used a Fluke device, but maybe "AMPL" means amplifier and
"UNCAL" means "uncalibrated"?

You can download the complete manual here:

It's a DejaVu-File, you'll need the free plug-in for your browser to see

Hi there..

We have some very large, very, very expensive Hayley Industrial
Electronics UPSes... Amazingly these UPSes have NO method of us getting
telemetry off of them as they exist now! They only indicators we have
are the analogue guages on the front. These guages measure the load in
Amps, Voltage, and frequency. We'd like to measure the following
conditions within the UPSes, and either have that information accessible
via a serial device or on the network (Items with a * are available on
the analogue guages):

- Input voltage
- Input Cycles
- Cabinet operating temperature
- Battery plant operating temperature
- Battery plant voltage level
- *Output Voltage
- *Output Amps
- *Output Cycles

If anyone knows of anything we can use for this purpose, I would
appreciate any input... Thanks!

Regards,
Richard.

For any one of the above, you could use an external device such as a
voltmeter. There are some models that have either a GPIB interface, or
built in Ethernet. An external ammeter could also measure current.

I don't know about measuring cycles per second. That requires a more
costly instrument such as a digital oscilloscope/signal analyzer.

To use one instrument to measure all of the above is difficult. It would
require some kind of switch to measure different input sources.

Some sites that might have more information on such matters are:

www.agilent.com
www.ni.com

There is a considerable market for industrial control and remote
sensing equipment. That might be worth investigating as well.

Woodgate is right. Buy a cheapie.
Got one of these in Dallas? http://www.harborfreight.com/

Or learn to avoid current measurements as much as possible.
It takes time to open a connection and insert the amperemeter, and then
you have to restore the connection after measuring.

In most cases you can measure voltages and calculate the currents.

Make a few homemade shunts, like 1 Ohm and 0.1 Ohm, so you can insert the
shunt and measure the voltage over it, when there is no other way to find
out the current. The shunt can be a resistor or a suitable piece of wire.

I currently have one nice digital VOM. So I measure voltage, then current,
back and forth having to move the cable each time, which sucks. I want a
stand-alone ammeter that I can quickly place within a circuit, I think.
I
would rather not purchase another meter just to measure current and am
thinking that this might be something easy to build but didn't find alot
searching so far.

Do you guy's use a separate amp meter for this stuff? I am just a hobbyist
that likes playing around with things. One goal is to eventually build a
SW
transmitter. Should I try to purchase, build? I would prefer building. I
am
thinking I would like to be able to measure down to the microampere range.

Thanks for any input!

Well, I do approximately what you want. I have around the shop 3-4
miscellaneous meters in plain old sloping front panels. The meters are
almost free at the swap meet, the cabinets are the expense, but you could
fashion something yourself. Let's see, I have a 50 microamp, 1 milliamp, 500
milliamp and 5 amp units.

Leads are brought out through the top through a dual banana jack. For some
frequently used current ranges, I put some shunt resistors across a
stackable dual banana plug. By plugging the right shunt plug into the meter,
I get some ranges I commonly use; 10 mA, 100 mA, 1A, 15A.

You can laugh, but it sure beats wiring up range switches. Too, using the
dual banana jack forces you to unhook the meter from the source of power
before changing the shunt, which protects the meter from an open shunt
(burn-out) situation.

Hi, Jim -

For my current measurements, I bought an HP 428B (toob-type) off Ebay and
repaired it. The reason I wanted it was so I would not have to break
connections to measure current. Of course, one must have enough slack in
the wire to allow inserting the clamp-on probe.

Just an idea. Good luck.

Yup!!! I bought three of those HP 428B meters on ebay in one auction. One
of them had a problem, but was easily repaired. Old technology, but they
sure save the day when you need to jump around in a circuit and measure
currents quickly. They are capable of current measurement from 1ma full
scale to 10A full scale. Great equipment survives the ages.

Harbor Freight has DMMs on for $3.99. Buy one for each thing you want to
measure.

I've found common multimeters fairly accurate for measuring very small
currents.
The typical 1Mohm input resistance at 200mV full-scale drops 200nA.
(when I checked it, it seemed to be accurate).
Even my cheap $4(us) meter has a 200uA range.

If you put multiple wires through the core (like an AC line cord) they
will read about zero, unless there is a fault to ground, as they read
the difference between the two currents.

Though there exist probes like this that using some assumptions about the
geometry of the wire, and several sensors closely spaced arouind the
cord, can actually measure the current flowing through a balanced conductor.
 
Hi Peter

Big problem small low cost EIS!
I needed several unit (apx 5 units) for some work/test I am conducting and
found out that they are very costly and not so portable.
However, I perused and found a device that can be used with very little
hardware - but you may need to get some electronics help.
The device is the Analog Devices' AD8302.
http://www.analog.com/en/prod/0%2C%2CAD8302%2C00.html
They also do a demo board that is apx $100.
The device is a 2.7GHz RF / IF Gain Phase Detector. This device will work
down to 0.001Hz (and upto 2.7GHz) but you will need to switch in some large
capacitors.
The input impedance of the device is fix at 51R but can be safely adjusted
to apx 500R. However, using an opamp in unity gain configuration can give
input impedances of apx 1GR.

I have build several of these and they seem to work well.
As far as connecting them to a computer any cheap ADC unit such as the
Picotech (http://www.picotech.com/) devices prices at apx $100
Whilst this is a project rather than a turnkey solution it will save you
some money.

Let me know if you require any further info.

Wayne

I am looking for a portable potentiostat that would interface with a
laptop that would do Electrochemical Impedance Spectroscopy. Gamry is
offering an inclosure box which makes their potentiostat portable, but
this unit costs more than I would like to spend and offers more than I
really need. The reality of it is that all I need to do in the field
is EIS measurements, and not the other electrochemical methods. Do any
of you know of any units that would serve this purpose at a reasonable
price? Thank You.
