It can test the display error and return error of 19 kinds of indicators listed in national regulations and non-standard display measuring instruments.
(including 0-3, 0-5, 0-10, 0-20, 0-30, 0-50㎜ dial gauge, 0-1, 0-2, 0-3 , 0-5㎜ Dial Indicator, ±0.4, ±0.5㎜ Lever Indicator, 0-0.2㎜ Lever Indicator, Probe Travel 0.6, 0.8, 1.0, 1.2, 1.6㎜ Inner Diameter- display, 0-0.8㎜ inner diameter dial gauge) .
The vertical grid indicator computer calibration instrument is a new high-tech measurement and testing product that integrates optoelectronic and electrical machines. The product has the advantages of improved accuracy and no return error, stable and reliable work, convenient operation, convenient carrying, easy installation and storage of verification data, etc. It can be used to verify dial indicators, dial gauges and lever indicators of various specifications. , display errors and return errors desInside diameter meter (adding non-standard verification function) and evaluating and processing the data according to the verification specification.
This instrument closely follows the national standards, fully complies with the requirements of the national verification regulations and provides updated software.
The instrument has the function of manual control and automatic timing control for test data collection; it has the function to pause at any time to prevent operation errors and wrong data changing; it is equipped with a verification of out-of-tolerance sound prompts and voice prompts; You can choose. The level of verification data digits (verification resolution 0, 0.00) is used to improve the consistency of verification results of the same watch.
The device is easy to use, offers high verification and printing efficiencynz and checking a watch only takes 3 to 8 minutes.
The device can print verification logs in three ways and print verification certificates and calibration certificates directly.
The device software is easy to use and manage (with sampling function, search and time range search function as well as data statistics management).
Operating principle and structure:
The computer grating display gauge checking system uses many gratings with equal spacing to create a length measurement The principle is this , to convert the linear displacement into an electrical signal through the interface circuit (pre-amplification, phase division, shaping, electronic subdivision), convert the light into a sine wave signal into an electrical pulse, and communicate with the computer, then the verification record through counting and data processing through the printer of the output deviceprinted.
The verification device of the whole machine (grid sensor, communication interface box, packet signal shaping circuit) consists of a DC 5V power source, a computer, a printer and three parts. The product is now integrated into the whole machine (direct communication with the computer via the 9-pin serial port output).
There is a buzzer behind the sensor. If the power supply is connected correctly, the buzzer will continuously sound four beeps (at this time it is communicating with the computer).
The nine-hole socket connects to the host computer's serial port. The instrument is equipped with a regulated 5V power supply to power the interface box and sensors.
