Note that the IEEE and US curves are set differently to the IEC/UK curves, with regard to the
time setting. A time multiplier setting (TMS) is used to adjust the operating time of the IEC
curves, whereas a time dial setting is employed for the IEEE/US curves. Both the TMS and
Time Dial settings act as multipliers on the basic characteristics but the scaling of the time
dial is 10 times that of the TMS, as shown in the previous menu. The menu is arranged such
that if an IEC/UK curve is selected, the I> Time Dial cell is not visible and vice versa for the
TMS setting.
