The accuracy does not match the specification. 
 
Make sure the device is powered On for at least 30 minutes. This is 
necessary to stabilize the unit to match the specification. Some 
specifications require the operating temperature to be stabilized at 
23˚C±5˚C. Please see the specifications for details.
