The PC can request two types of numeric measurement data from the AccuSetter:
1. Current Data — Current measurement readings being displayed on the Accu-Setter.
2. Saved Data — Measurement readings stored in the Accu-Setter’s memory. The Accu-
Setter can store the active reading. The storage function is initiated by the operator.
To request current measurement data, a 2-byte request packet must be transmitted to the
Accu-Setter:
