Temperature:

C to 45
°
C
The 54522, 54523, 54591, and 54593 Track and Hold Clock Cards operate at
any ambient temperature within this range; however, their performance to
specification requires two additional temperature restrictions:
a. The ambient air temperature surrounding the track and hold cards must be
controlled to ±5
°
C with respect to the normal or average ambient
temperature. That is, the ambient temperature may reside within 0
°
C to
45
°
C, but the variance in temperature must be held to a 5
°
C deviation for
the duration of the measurement in order to guarantee the clock
specifications.
b. The slew rate of ambient temperature change, within the 5
°
C deviation
limit, must be limited to 8
°
C per hour.
