1.Within 1 hour after zero set, at a constant temperature, after a 24 hour warm-up of the power meter.

2.The number of averages at 16 (for normal mode) and 32 (for x2 mode), at a constant temperature, measured over a 1 minute interval and 2 standard deviations. For HP E-series power sensors the measurement noise is measured within the low range. Refer to the relevant power sensor manual for further information.
