The above equation is only a starting point. Adequate settling can be confirmed by triggering an oscilloscope on the rising edge of ITST (or alternately on SMBALERT using the mon_esr_done alarm). Observe the response of the discharging capacitors. They should have clearly settled into a linear discharge by the time specified in cap_i_on_settling after the trigger. If they have not settled in time, cap_i_on_settling needs to be increased. cap_i_ on_settling cannot be increased beyond 25 percent of the expected minimum measurement time. If 25 percent of the expected measurement time is inadequate to settle, the expected measurement time may be increased by increasing ?v via cap_delta_v_setting.
