Specifications describe the warranted performance and apply after a 30
minute warm-up. These specifications are valid over the power meter’s
operating and environmental range unless otherwise stated and after
performing a zero and calibration.
Supplemental characteristics, which are shown in italics, are intended to
provide information useful in applying the power meter by giving typical,
but nonwarranted performance parameters. These characteristics are
shown in italics or denoted as “typical”, “nominal” or “approximate”.
