Will reversing the source and load damage the meter? Does current flow backwards through the meter, or is there a diode preventing reverse current?

Website says it will not damage, it will just not read current flow. Thanks.

No. I have one set up on the bench. Apparently it's protected against reverse polarity :-) It shows 0.0 when powered on and the sampling wire is switched (white)

U can zero it by touching the leads together...most meters do the same thing and depending where u r there is electricity all around as is shown on am oscilloscope.

the controller prevents reverse polarity. remove the diode it does not do anything

Jaco, I've never put a meter on my trolling motor circuit under load, but I can tell you that a 55 lb thrust trolling motor under great duress (weeds, bottoming out, etc.) has yet to trip this breaker. I would be confident with the voltage and amperage you mentioned for both tripping when it needs to and not tripping when it doesn't.

I would not do that. I don't think it will give you a true reading of the battery condition. I ran a dedicated pair of wires from Positive & negative battery terminals to the meter. I installed a small toggle switch on the dash & broke the negative wire thru it so that the meter only draws current when the switch is on. otherwise it is always draining the battery. Hope this helps.

Oh my meter is a Fluke 375. But the Fluke 375 and 376 are brothers. Absolutely! That is one of the nice advantages of this meter. The inrush current feature works on the DC ammeter also. I was measuring 12 volt inrush DC engine starting current of our home standby generator with it in addition to measuring inrush AC starting current of compressors.

It is not set up to reverse, however, it is a two wire 12v DC motor, and you could put a double pole double throw (DPDT) switch in the power feed to reverse the polarity, and thus the motor direction

I'm sorry....I can't answer that, but, if you call the company that made your meter....they should be able to answer your question.

i fried one by reversing the in put . i now use a checking diode to keep this from happening .

I think the short answer is no. the unit has internal current limiting and fuses that are listed as "reverse polarity protection". I would recommend you download and read the .pdf manual at http://www.progressivedyn.com/pdfs/109821F%20english.pdfHappy Trails!

Attach a multi-meter set to measure dc volts, to both wires, just like testing a battery. If the movement is off the grid, then the wires are reversed. If the meter tests correctly, then the polarity is correct.

I just used a 12v adapter I had lying around. I cut the end off and used a multimeter to make sure the polarity was correct and hooked it to the board. Please, do be careful about the where you put the positive and negative. I remember reading on the net that this device won't protect itself from reverse polarity on the dc voltage. Meaning, the circuit board will be ruined.

I just put an ohmmeter across the heavier gauge black and white leads of my meter (out of circuit and powered down) and I got a dead short. So yes, when powered off, the meter will pass current through the black and white leads.

There are a couple of pins provided on the side which when connected (with a pushbutton switch, not included with the meter) would reset the amp-hour, watt-hour, peak watts and peak amps readout. Also, if you disconnect the unit from both (source and load) sides, the readouts would be reset.

After checking the manual I think the answer is no. There is wording in the manual:"To measure current, you must break the circuit under test, then place the Meter in series with the circuit." There is a clamp on style attachment. Of course that would only measure large Current Flows. Other replies seem to say there MAY be a special probe for small current values.

Actually I hooked mine up backwards and nothing happened. On the back of the box it says it has reverse protection, short circuit, reverse night current, overload, and overcharge/discharge protection.
