I have multiple multi-meters here (Well Electronics is my hobby and I have some wallpaper (School certificate) in the field) ONE of them is a Crafstman (Sears) 82-369 This is a clamp on AC/DC ammeter, volt meter, Frequency meter, Bunch of other meters (Resistance too) and THERMOMETER (remote reading)
The DC ammeter function has identified two bad batteries by noting differences in current flow.. THIS was without having to disconnect them, Once disconnected a volt meter confirmed shorted cell (Actually I used a different volt meter for that since that one is part of an "Offline battery tester".
Tonight the temps are getting into the "Scary cold" range (For an RVer that is less than 20 degrees) For the first time since I started parking here,, Now being from Michigan I made some mods which extend the "Scary" temp down to 10, but ... Well the screen in front of me is improving, it's up to 9 as the expected low tonight.
I'm not sure I have enough heat in the basement without running the furnace and burning expensive propane instead of included in the site rental electricity.
I dropped the sensor in beside the GRAY tank, and will monitor the temps in the wet bay from the comfort of the hall closet above it using that meter, if it gets too low.. I'll start killing off (Shutting off) Electric heaters inside (Leaving the lights and heaters in the bay on) and fire up the furnace to blow heated air down there as well.
A very handy meter. Even helped me fix a Christmas decoration this morning.
