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 shown in Table 2-1 .
IMPORTANT Avoid unnecessary handling of the devices during calibration because your fingers act as a
heat source and may increase the temperature of the device.
