in ppm/°C, is 10

), where ΔV
R
is the lowest value subtracted from the highest, V
R[25°C]
is the value at 25°C, and ΔT
J
is
the temperature range. This parameter is ensured by design and sample testing.
(6) Hysteresis is the change in V
R
caused by a change in T
J
, after the reference has been “dehysterized”. To dehysterize the reference; that
is minimize the hysteresis to the typical value, its junction temperature should be cycled in the following pattern, spiraling in toward
25°C: 25°C, 85°C, −40°C, 70°C, 0°C, 25°C.
(7) Low contact resistance is required for accurate measurement.
