It usually takes about 2 seconds. It's an auto ranging meter so it takes a second or two to get into the correct range and display the reading. The Pro of the SC53 is the price at around $100 and the Con is that it does take slightly longer for it to display. Our higher end meters such as the SC54 ($149) and SC57 ($269) are faster. If it really is taking 4 solid seconds you may have an issue and you can call Fieldpiece at 714 634 1844 and we'll arrange a repair or replace.
