Profile Projector Digital Readout

profile projector Digital Readout

Digital readout is a multi-function digital display processing system, which is used on profile projector to finish precise measurement of geometrical work-pieces. Work-piece measurement includes work-piece adjustment, creation coordinate origin, measuring work-piece via sample collection etc.

1.2 The Name and Function of Each Parts

This section describes each part’s the name and functions of DP100 digital readout.

1.2.1 Front Panel Introduction

Chart 1.2.1 Front Panel：

1)、Small LCD screen

Display operation cue

2)、Large LCD screen

    Display measuring results etc.

3)、Keyboard

Through Keyboard, you can create kinds of settings and input data

1.4 The definition of the term commonly used

This section introduces the definition of the term commonly used of DP-100 digital readout to help users understand the contents of the manual.

1.4.1 Graphic Elements

The basic graphic elements generated by DP-100 includ point, line, circle. The angle and distance is the combination result of the above graphic elements, but in DP-100 they still are looked as graphic elements. Graphic elements are short for graphics, graphic element or element.

1.4.2 Graphics List

When new graphic is created, it will be put into the graphics list. DP-100 can save 100 graphs (001-100).

1.4.3 Sample Collection

In Measuring, the coordinate data of a special point put in DP-100 system, the DP-300 calculate the correct measurement graphics process. These graphic elements used to create the special point are the sampling points. Except for the measurement of distance and angle, the max points for other graphics measurements can up to 50 points.

1.4.4 The Method to create Graphics

1、Measure the Graph

Collect sample points on the work piece to create graph

2、Preset the Graph

Put the necessary information through the keyboard to create new graphics

3、Create the Graph

Put the previous generated graph portfolio into a new graph.

1.4.5 Recall Graphic Elements

Rapidly orient an already existing element in the list.

1.4.6 Coordinate System

1. Relative / absolute Coordinate Ssystem

Absolute Coordinate system refers to the basic coordinate system  

Relative Coordinate system means the coordinate system which is relative to absolute Coordinate.

2. Polar /Rectangular coordinate

Rectangular coordinate expresses a point as with (x, y)

Polar angle coordinate expresses a point as with (ρ, θ)

 For Example：LCD dispalys“The current coordinates location”

             X window displays 1.000

             Y window displays 2.125

It means the current coordinate is（1.000，2.125）, but if convert polar coordinate is（2.349，64.799） , the display interface is as the chart 1.7 show.     

Chart 1.7  Polar coordinate display

Note：If it displays polar coordinate in small LCD, the coordinate system in large is rectangle coordinate.On the contrary, If it displays rectangle coordinate in small LCD, the coordinate system in large is polar rectangle coordinate. 

1.4.7 Measurement Pattern

There are two kinds of measurement patterns, One is that before measuring, pre-set the measurement points (max is 50 sample pionts); another is that before measuring it is no need to preset the sample points quantities which will be decided during measurement. You can choose any kind of measurement pattern via presetting in the internet function setup.

1.4.8 Function of Coordinate Rotation (Coordinate Adjustment)

DP-100 digital readout provides coordinate rotation to improve measuring precision and in order to improve the measuring precision, and make the user feel more convenient. The main purpose of coordinate rotation is help user to adjust the work-piece postion.

When the work-piece edge is irregular or has angle with X-axis, coordinate rotation function allows the operator rotate X-axis to the edge position of work-piece to improve accuracy and to be convenient to measure.

1.4.9   Input Numbers

After putting in numbers, press  key to confirm input number. Press key to cancel input number.During putting in, press  key to cancel the number put in last time, also can press  at the beginning, it means that you put in the default number displayed on the screen.
