Set to Ohms, I touch the two probes and the reading will go all over the place and never settle. Is this normal on your DL389 too?

I saw on another review for this meter line that this problem went away when they sent him some higher quality test leads, so may want to try better leads.

tried this today and when probes are not touching led reads O.L and when touched reads 0000.0

Not for me - slow steady gradual movement of gauge needle as charging progresses. Make sure you have it switched to the correct charging mode (auto/manual) and voltage (12/24v) for your battery.

It may jump around a little at first. My Fluke would do this on DC Volts. Try testing an wall outlet and then when you have a reading and have disconnected it should stop flashing.

Use the Min/Max function. When it's blinking, activate the circuit and then cycle the Min/Max button to read values. Keep in mind, if you have the clamp probe turned the wrong way a negative value may show as "Max." Hope this answers your question

Hi Harold - there must be a defect then. I set mine for 345 and it stops at that - it will fluctuate a few degrees down when in use - but nothing major. I would contact them and have it replaced

I am using a 470ohm in mine. I have a lot of failure with this batch.first batch came as positive ground. The second batch came as negative ground. I have not used the new ones yet.

I am having the same problem...brought it back 3x without success...also temp guage not working properly either

It might be that you have the meter connected wrong. Check to make sure the pos connection is on the first battery and the neg is on the last battery. I have the same meter and the needle fluctuates very little. I am thinking about changing to an LED one.

Just took a multi meter to them while off. It read 0.5 ohms across 3 LEDs @ the cut points... Hope that helps.. Doesn't seem right to me for some reason...

I haven't had any trouble with mine. When immersed or poked into something, I get a reading within a few seconds, max.

Make sure the polarity is correct. Also make sure there can be no motion for it to detect. These are sensitive units. Good luck!

I've got the same gauge. same problem. I keep my batteries charged but the needle stays in the white until I run the cart. Then it goes down into the green. Don't know what that means or what the red means. I looked up the company on the net but couldn't find this guage listed. Amazon should contact this seller and discontinue selling this item. Like you, know instructions were included.

You shouldn't have to. So, there's a stray current you are measuring, or there's something wrong with your meter. I'm assuming you only have one wire going through the jaws, and that you have the wire centered as best you can. Is your reading off in all ranges?

That sounds like a short in the line somewhere. Occasionally mine does this as well, and has since it arrived, and I have not been able to remedy the situation. After researching it, I found both should work evenly all the time and this is a problem. Sounds like we need new wires.

I'm also using.035 wire with mine. You will need to run a bit hotter then what you chart calls for.

I bought those too, the readings with the no-calibration strips still came out as 0.1's almost all the time with occasional 0.2's just like the first set of calibrated strips that I had bought with the meter originally. I'm an engineer and don't know exactly how they do it, but nanoscale manufacturing these days is doing amazing things so maybe the calibration sample is on the strip sub-microscopically and we simply can't see it. Just follow the instructions and be happy.

Sounds like maybe the ground wire that attaches to the receiver/amp has possibly come loose. Maybe in installing the cartridge, it worked its way loose.
