   Inaccurate clamp meter?

   I got hold of a second hand one of these:   
   https://www.torontosurplus.com/rs-components-heme-100-clamp-mete   
   -611-414-clampmeter.html   
   A HEME 100 clamp meter.   
   I can't find specs for it online, only a HEME 1010.   
   I've tried reading a few currents with it (using a brand new battery in it),   
   and it seems to underread a fair bit on DC (0.56A instead of 0.62A) and AC   
   (7.5A instead of 8.5A).  It's also susceptible to wires near it - for example   
   if you put the live    
   inside the clamp but the neutral is an inch or so from the outside of the   
   clamp, it reads a bit of that too and gives a higher reading.  Are these   
   things supposed to be accurate?  Can I adjust it?
