Have bespoken tape measure a tape measure to pay attention to in the home, I also just know, tape it incredibly still hidden a few small organs, let's get together to understand the below.

Sounding steel tape zero detector (steel tape zero calibration table) is according to the regulations of the JJG4-1999 verification regulation of the latest research and development of sounding rod of zero the special instrument for verification. Sounding steel tape zero detector can quickly check sounding ullage rule of error value of zero to 500 mm. The instrument has simple structure, reasonable design, convenient use, is the ideal of the metrological verification department detection tools. First of all, let's take a look at the Numbers on tape measure, small make up the hands of the tape custom tailor tape with a 64 mm, and that figure represents a tape measure shells transverse diameter, with this number, so we are in the measurement of the corner, would be more convenient.

Three, directions for use:

1. The first four leveling adjustment screws [9], the instrument is in steady state.

2. Use standard scholastic furniture check zero line and rod [4] error between the center line, general factory has been set.

3. According to the feet stink bespoken tape measure adjust the clip [5] lead hook height diameter, diameter more hours to raise the feet mound. Feet stink at larger diameter cut, make feet lead the centerline of the [6] is about 1 mm higher than mesa, then turn the handle [8] let the clip lead hook [10] clamping feet stink. Feet through the pulley [3], [1] by clamp feet again grip the feet, with Jordan farmar (2) load for the feet, make feet with flattened in mesa, the foot with a side should keep parallel to the edge of rod [5].
