Very nice unit and was calibrated a few years ago.
The fluke was cal'd only a year ago and as you can see they read the same to within 10mV.
Current is also very accurate and to be honest the 118 is likely to be more accurate than the ISO-TECH reading.
Battery inside needs replacing, will work if left on charge for a while but battery doesn't last long.
After a while of being unplugged it needs to be left to charge before the meter will function, these problems won't exist with a new battery.
