In the IDMT, the user can also program the characteristic using time-multiplier-setting
(TMS) for the required operate time. For example, when the IEC characteristic is selected, the
user can set the TMS value using the setting [
OC1-TMS-IEC
] (incidentally, the default value
for the TMS is 1.00). The other TMSs are also available by the [
OC1-TMS-UK
], [
OC1-TMS-
IEEE
], [
OC1-TMS-US
] and [
OC1-TMS-ORG
].
