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
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.
