1 Scope

This procedure applies to the first end of the production line and is used for quantitative packaging of the cable meter (hereinafter referred to as the meter) Verification, subsequent verification, and inspection in use.

2 Overview

The meter is a measuring instrument used to measure the length of a wire and cable in an absolute method. The meter is mainly divided into two types. standard meter and work meter. The standard meter is used for on-site verification of metering devices such as Figure 1 (c). The working meter has a meter for the cable quantitative packing meter as shown in Figure 1 (a), and the cable manufacturer uses it online. The rice device is shown in Figure 1 (b), (d) and so on. The shape of the instrument is shown in Figure 1. The principle of the instrument is shown in Figure 2.
