    Earth leakage problem on Kärcher pressure washer

    Pulling things apart before any testing to acertain any problem is simply crazy. It prooves nothing electrically.

    RF module not working at all. What am I doing wrong?

    From my reply #2.......... The Tx units can be bound with any of the receivers following the instructions. Best to print it out and keep it onhand as you will forget.

    Earth leakage problem on Kärcher pressure washer

    Can't help but notice a touch of de-ja-vous here. This is how it all began and I explained everything to you. Did you not read what I said..?

    RF module not working at all. What am I doing wrong?

    Good stuff. If you need "small" then there really is no other battery than LiPo for good capacity. Thing with them is, a small 3.7v single cell (say 500mAh capacity) would be about the same size as you wireless module. When more voltage is needed, like 12v in your case,the cells are stacked...

    RF module not working at all. What am I doing wrong?

    Solder bridge, well , mmmm...might hold. You also need a negative wire from your DC power jack inline socket (black) to your wireless unit negative terminal. Before you switch on, just temporarily remove the Red cable from the jack socket, and.......... .................If you have a...

    RF module not working at all. What am I doing wrong?

    Simply show me what you connect to where BEFORE powering up. And for the sake of Nelly, get rid of those b*** button cells and use a decent supply.

    Show a photo of how you have it connected BEFORE you turn power on.

    RF module not working at all. What am I doing wrong?

    Ok...... you can supply both from the one 12v battery. First look at the photo number 5 at the bottom in your link which shows an underside view of the wireless board. You will see a pcb trace coming from the common terminal of the relay on the right side all the way over to the left side of...

    Now you are starting to understand. so....1 step at a time here. What voltage does the DROK operate on...?

    RF module not working at all. What am I doing wrong?

    No, you have to get this idea of these little batteries powering devices with a specified current demand. Battery power is fine as long as you go up in capacity, say (for example) 8 * AA NiMh batteries in series or a decent 3 cell LiPo. I beg to differ. To repeat, see if it will sink in this...

    Have all the UPS makers switched to no consumer battery replacement?

    Most are designed for throw away....one of the things one has to get used to. No service information and no parts, some even deliberately remove any sign of active component detail. Units are commonly built as OEM and in modular form which makes things even worse to decypher.

    Earth leakage problem on Kärcher pressure washer

    Show the meter, I'm not Mandrake. As I sad previously, test requirements would depend on what the trip was,overload on the breaker or safety switch trip.

    RF module not working at all. What am I doing wrong?

    To begin with the specs say 12v operation so forget the smoke alarm battery and connect to some decent supply. A 1A 12v DC power adaptor should suffice. The output with these is normally a set of relay contacts commonly known as voltage free. By the look of your output you have nothing...

    Earth leakage problem on Kärcher pressure washer

    Unless there is a 500v megger range in there you are wasting your time. Metrel brand would be a bit of an overkill for a novice. Any of the Uni-T range of meggers would have done the job.

    Help with measuring AC current

    Wow, that is OLD......taken from the manual.....may be important.....The AC current modes do not use an AC coupling capacitor to block DC. Both DC and the AC current flows through the shunt resistance. Too much DC current overpowers the AC component. lf you need to measure the AC component of a...

    Earth leakage problem on Kärcher pressure washer

    You did but the length of the test leads is a killer...o_O What you can do to assist the lecky is take note of the indicator/ s on the safety switch when the fault occurs.

    Anyone here ever programmed an FPGA?

    Quite a few with the same thoughts I think.

    Earth leakage problem on Kärcher pressure washer

    Multimeter in this instance will be of no help. You need first to determine whether overloading the circuit or tripping due to earth leakage. Then, if the former, a site check to see why it is overloading, possibly because you are running on an extension lead. Or/ if trip is due to earth fault...

    Earth leakage problem on Kärcher pressure washer

    Earth leakage units are sometimes combined with a circuit breaker and commonly known then as a "combo" , or RcdMcb. ...typical example shown below of a 2 pole unit, there are also single pole. One would need to look at what indicator comes up when the power turns off so one would know if it was...
