1 Rm: Measured resistance value [
].
Vs: Voltage setting [V].
Vo: 0.1 [V] (Vs 200 V) or 0.5 [V] (Vs > 200 V)
2 When the temperature (T) range is 2065 C.
Multiply both the rst term and the second term (the value in parenthesis) by the following error factors when the
measurement time mode is set to SHORT or MEDIUM, or multiply only the rst term by one of the following error
factors when the measurement time mode is set to LONG,
8T<18 C, or 28<T38 C : 22
0T<8 C, or 38<T45 C : 24
Multiply the second term (the value in parenthesis) by the following error factors when the measurement time mode
is set to LONG,
8T<18 C, or 28<T38 C : 25
0T<8 C, or 38<T45 C : 225
3 When measuring a grounded DUT, multiply the second term (the value in parenthesis) by one of the following error
factors according to the measurement time mode:
SHORT : 22
MEDIUM : 21.5
LONG : 21.25
4 Im: Measured current value [A]
5 When the test cable length is 1.5 to 2 m.
6 After 1 second from range changing.
7 When the contact check function is ON, multiply the second term (the value in parenthesis) by 1.5.
8 When the Oset-Error Canceling is OFF.
