Easily test the resistance of your atomizers, cartomizers or clearomizers. You can also test the output voltage of your batteries with this meter. The meter comes with threading for use with all 510 and eGo threaded parts.
When you turn it on, it will be all dashes.
Screw on an atomizer and it will show the OHM's. Screw on a battery and it will show battery level once activated.
If both are screwed on, it will show battery under load.
The unit has an internal battery that is recharged with the included micro USB cord.
The meter will display a --- or 0 in the first digit to the left if there is no current flow from battery to the tester, or "888" indicates error or not able to read.
The test amperage is a mere 3 milliamps to prevent any damage to the coils in the items being tested. Generally Accurate to 0.4% (but can fluxuate depending on the coil and attachment)
