No good. Needs 160v minimum to opperate

The Blue Streak has a 230volt 50 cycle generator in it.

I don't think it's feasible, Rob, from what I can see of the specs.
It merely samples the output voltage (160-250 or so) and has a simple built-in frequency counter to display that parameter.

G'day,

I would like to monitor:
240 AC Voltage
50 AC Hz
Total amps being drawn by all AC powered equipment on The Blue Streak
I would also like to find the same kind of meter for Double Trouble in the USA.
I have a Kill-A-Watt but you can't monitor any device that's hard wired into the AC system.
I assume that I would have to wire this into the main supply buss just ahead of the circuit breakers. Double Trouble has CB's for
the front A/C, the rear A/C. the water heater, and the wall plugs. If I turn on those C/B's one at a time I could see how many amps
each item is drawing. Since the wall plugs feed the PD Convertor, fridge, microwave, etc. I can do the same thing with them.
Regards,
Rob M.

Rob,
I was curious about the specs on your second entry. When I saw that the
essential current transformer was not included, I checked "other items".
Before I found the transformer, I found this, which appears to meet your
need at much less cost, is applicable to 120 vac also, and DOES include the
current transformer:
http://www.ebay.com/itm/3-in-1-Red-LED-Digital-Meter-AC600V-100A-Voltage-Current-Frequency-power-DC12V-/310855695453?pt=LH_DefaultDomain_0&hash=it em4860717c5d
http://goo.gl/oSZ4sg
There are others further down the list that have additional features, such
as dual displays and power functions. I never did find a listing for a
current transformer for your choice.

Rob,
That instrument will do what you want, but it will need a current transformer (a heavy donut with two wires exiting) to enable it to read current. They are vary available and not expensive. The instrument says its default calibration is for a 500/5 CT (current transformer) but it says others can be applied. I would suggest you look for a 100/5 for your coach application.
Now I would like to find one for 120V 60Hz.

Ken,
Well spotted! The unit you found is mo betta!
I'd like to install it near the Avion Panel which is above the pantry to the left of the entry door. I assume that I will have to
run a wire through the current transformer to read amps. In the picture the wires from the current transformer to the meter are
short, would it still work if I ran the two wires from the main input buss to the circuit breaker panel on the driver side, across
the ceiling, forward about 4 feet, and then down a foot or so to the meter?

Rob,
The current transformer for ac current is analogous to a shunt for a DC
ammeter. The shore input line must pass through the transformer core
(donut); the smaller wires go to the meter, which can be 'most any distance
away.

Ken,
THANKS! That's what I was hoping you would say!
I've sent an email to the seller to see what kind of deal he'll do for three of them, one for The Blue Streak, one for Double
Trouble, and one spare.

If it will measure very low voltages, you could use a shunt. Otherwise, you're scrod (Pluperfect subjunctive of 'to screw').

I note that the CT is not included. You'll need the spec the meter wants for a CT.
