Accuracy is usually specified at the calibration temperature (T
temperature range. This is a common temperature range for many operating
environments. You must add additional temperature coefficient errors to the
accuracy specification if you are operating the multimeter outside the ± 5 °C
temperature range (the specification is per °C).
