Note 1: Custom values (Customer specified) of nominal resistance from 5 µΩ to 1 Ω are available by special order.
Note 2: Maximum current for natural air convection use without damage to the unit is the same as the maximum current when used with the
92310 forced convection unit.
Note 3: Defined as maximum variation of resistance value as initially adjusted at time of sale, temperature 23 ºC ± 2 ºC.
Note 4: When used as a standard resistor at 1 watt Level only.
Note 5: Typical specification defined as the time for the resistance value to settle to within 10 parts in 10
6
of the final value for any change in
applied current. The time constant is typically 1 minute for flowing oil.
Note 6: The 9230A-15R is the direct replacement for the 9230/15 version shunt. The 9230A-30 has the same resistance value as the 9230-15R
and can be used up to 30 A.
