any others?
so after my third martini 56 meter in a year pooped out on me, i decided to get another exstik as mentioned here (the first one i bought was DOA). I am using it for the first time today and it seems to have the same issue i encounter with so many other meters....
i calibrate in brand new 7 and 4 buffer. so far so good. measure a few water samples (at room temperature). still good. walk away long enough for the meter to time out and turn off while sitting in the water sample. come back ten minutes later and the meter is off by .3 (sometimes high, sometimes low). put it back in the buffers and recalibrate. then it works fine again...for a few minutes...
i'm starting to think i am cursed. maybe its me? should i be keeping the meter in buffer solution when not in use (even for a few minutes). when i am done for the day i store it with buffer 4 in the cap....
or do i just need to suck it up and by a $300 benchtop?? would that even make a difference?
