Anyone know why my current reads zero even though voltage is working? I need both current and voltage at low settings....

Either there is nothing drawing current or there is a short circuit and the supply turned itself off to protect its hardware.

What kind of load do you have hooked up? If it's an open circuit, there won't be any current.

Either you have an open cat or your meter lacks sensitivityAlfred Bunge answered on June 11, 2014Edit this answer

Lucas, have you connected a load to the output of the power supply? No current will be drawn if the circuit is open .

Well, current will depend on the draw of what you are connecting it to. you could put an inline resistor if needed. To control the voltage, you just turn the pot screw until the meter reads the voltage you want. you could do 12 or 18 volts with a turn of the screw driver. basically, this should do exactly what you want.

Thanks, i'll check for the switch on the back tonight. i'm sure the polarity is correct, red to lead (+) and black to ground (-) right?

hi, could be due to problems of energy. Check the feed if using PoE , could have a poor voltage. My happened to me something!

You have to use a "Shut" to wire across for the current to be measured. The voltage will be measured when connected to your source. I don't remember the wiring sequence, but it was spelled out in the instructions. If I remember correctly Yellow goes to the shut, Red - Source Positive, Black - Source Negative. You would need to double check my memory for accuracy.

HI Stew. I used 200ohms to drive 4 RGB leds in parallel with source of 9volts. All four connected to same resistor. I haven't measure current or voltages but they bright pretty good. let me know if you need any measure.

I just searched mine again for any indication of dual voltage. Mine is 110/120V only.

It is possible that your light requires a constant "current" source (since you mentioned 32-36V), instead of a constant "voltage" source. This is a constant voltage source, 12VDC.

I see that another answer conflicts with mine. Perhaps I should add that I tried this before answering. It works fine. I think the secret is that the modules have an onboard voltage regulator. The input is always referenced to ground and really doesn't care what you connect it to.

Funny that you asked me this question... I am an Electrician by trade, and I have No Idea about the DC low Voltage on this perticular component..? I just matched it with the other 4 GB Ram memory board that came with the pc... I can take a reading, and get back with you on this, but normally I wire homes dealing with AC Electrical Current...

I don't know your particular setup but you need to separate voltages, one to power your volt/amp meter and the one your wanting to monitor. The you monitor you need to setup with your shunt, you have to use a shunt for it to work. If you don't set up a shunt amp meter will show nothing. I hope this helps.

When testing polarized parts, such as a diode. It should only allow current in one direction. When you try to push current through it in the wrong direction it will read .0L, because it wont let anything through. I had to check diodes for a power supply. When I connected it in the correct direction, it read .5, but in the wrong direction, .0L.

There is a voltage issue, sadly. You need a step-down transformer, which is what I use.

Consider using multistrand, connector wire - it has less resistance. Check the current under various lighting conditions. Good Luck

This is a frequently asked question. The voltage was apparent, however the amperes was guess work and I got the 50%-50% choice wrong. I emailed the seller and they replaced it no charge so I used the other wire. The meter has worked flawlessly for several months.

Question doesn't make much sense. To get more current, you'd want to step the voltage up.

It is not low voltage. I already had the post, so I can't answer that portion of your question.
