I see a screwdriver is required for calibration. Do new units ship being pre-calibrated?

    Instructions tell you virtually nothing. No batteries, No calibration chemical. This was my 2nd try @ a relatively inexpensive meter. Shows it all lit up so any normal person would assume the batteries were included. You would also think it would come pre calibrated. Not the case. DO NOT BUY!

    Excellent product and excellent value for money. It is a bit slow to stabilize the correct measure. Excellent purchase.
