Temperature—What to Watch Out For
Changes in temperature can affect electrical characteristics. Therefore, the operating
temperature is a critical factor in performance. During a measurement calibration, the
temperature of the calibration devices must be stable and within the range specified in
Table 2-1.
IMPORTANT Avoid unnecessary handling of the devices during calibration because your
fingers are a heat source.
