When we were in the measurement of the corner, almost
personalised tailor tape double the tape measure is measured, if we
use this method to measure, so the corner will have a small Angle, then measured the distance is not standard. In fact, when we were in the measurement, can put the tape measure to measure
directly, if the ruler is 10 cm above, so the total length of the distance, is to add 6.4 cm, 10 is a total of 16.4 cm, as usual, when measuring the corner, we use this method to measure, then
measured the distance will be more accurate.
Then we take a look at the tape head this hole, the
retractable tape measure sewing holes has what effect? As usual, if
only one measuring distance, an object, there is no place to hang on, then we can on the objects above nail a nail, and then drove the card into the hole, used to fixed tape, so that when we
measure, even a person operation, also can compare the distance measurement.
Then, let's take a look at the tape head small grooves, the little grooves, is convenient, we use for marking mark if we are measuring the distance of the ground, the distance and the ground is
more than the total length of tape, so we press the tape head, sliding around, marked out on the ground, so that we can rely on this tag, continue to measure the rest of the distance.
Tape measure zero detector (steel tape zero calibration table) is
large print tape measure according to the regulations of the
JJG4-1999 verification regulation of the latest research and development of sounding rod of zero for verification of special instrument table. 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.
Tape above the stainless steel clamp, the clamp to normal use, we are used to receive a tape measure to use, as usual, we at the time of measurement, take with a tape measure, and we can put tape
on the waistband, or the card on the top of the belt, when we measure, with will be able to get a tape measure, so it is more convenient we take.
