I don`t have that specific ohm meter but I noticed that they can be temperamental when it comes to certain devices.
Likely not making a connection there...extend the 510 pin on the corolla (if possible)
I have had to resort to using a heatsink on my ohm meters to ensure a good connection (or any connection at all sometimes !)
to save me from altering my atomisers - the spring loaded connectors in ohm meters aren`t fit for purpose in many cases.
Kepler Style 510 Heatsink adapter with adjustable screw
^one of those type things.
The adjustable screw on the heatsink/adapter means I can get a permanent good connection with the ohm meter and also that I can screw the atomiser down tightly enough without ruining the meter.
Can also use short and long 510 atomisers without needing to touch anything.
The springs in the ohm meters are poor, I think.
I have several but currently using a Coil Master 521 Mini, the CM 521 full size previously - both needed the adapter for a good connection every time.
~~~ Edit:
Additionally, the cheap ohm meters got tossed as they were wildly out most of the time and broke as soon as you looked at them but even the allegedly accurate one from "usaohmmeters" needed the heatsink due to the weak spring - bad connection.
The "Smoktech Omnitester" was OK iirc as it was not spring loaded but even then I ended up using a 510-510 adapter to deal with short 510 atomisers.
Thanks Fad! I'll see if I can get it to work by extending the pin per your suggestion. Thanks for the information on the heat sinks too. I think they would be a very good addition to my stash.
