Perfect but false measure requiring calibration

Hello, the few flaws I found him:
. End cord too short.
. 11,4v measured for 12V and 4.6V to 5V. Checked with another calibrated multimeter. I had to open the meter and touch the (only) potentiometer.
. Paw difficult keeping to unfold
. The probes should be well down if no measure.
Getting to share its few flaws that are not big problems is good business for 12. It feels good in the hand.
