TR200 Surface Roughness Tester Instruction Manual

1 TR200 Overview

1.1 Introduction to TR200

TR200 surface roughness measuring instrument is a small handheld instrument suitable for the production site environment and mobile measurement needs. It is easy to operate, comprehensive, fast, stable, and easy to carry. It can measure the main parameters of the latest international standards. The instrument strictly complies with international standards.

1.2 Measurement principle

When measuring the surface roughness of the workpiece, the instrument first puts the sensor on the surface of the workpiece to be measured, and then starts the instrument for measurement. The precision driving mechanism inside the instrument drives the sensor to slide along the measured surface at a constant speed. The sharp stylus feels the roughness of the measured surface. At this time, the roughness of the measured surface of the workpiece will cause a displacement of the stylus, which will cause the inductance of the sensor's inductance coil to change. An analog signal proportional to the measured surface roughness. The signal is amplified and level converted into a data acquisition system. The DSP chip performs digital filtering and parameter calculation on the collected data. The measurement results are given on the liquid crystal display. Output on the printer, can also communicate with the PC.

1.4 Names of various parts of the instrument

1.1 Button definition

: Activate the measurement key. Used to start instrument measurement.

: Power on / off key. On-off key for daily use, it does not turn off the battery and retains stored information. If the instrument will not be used for a long time, turn off the battery switch on the rear of the instrument.

: Up arrow / parameter key. In the main interface, press this key to enter the parameter display interface, and press Enter to exit.

: Down arrow / store key. In the main interface, press this key to enter the storage record interface.

: Left arrow / graphic key. In the main interface, press this key to enter the graphic display interface.

: Right arrow / print key. In the main interface, press this key to start the printer to print all measurement results.

: Settings / Menu key. In the main interface, press this key to enter the measurement interface setting state. Long press this key for about 3 seconds to enter the main menu interface.

: Enter confirmation key. In all interfaces, it is used to confirm the result of setting modification or exit this interface.

Special instructions for using the arrow keys:

The general definition of the functions of the four arrows: up and down and left and right: uniformly stipulated in all interfaces that need to be modified. It takes effect only after the measurement conditions are modified and the graphic display interface. It does not work in the main interface. In the main interface, these arrow keys perform only the functions indicated by the characters above.

1.1 Standard configuration

Note: The above list is for reference only, and the actual goods and quantity are subject to the packing list.

1.7 Sensor and host connection

1.8 Power on / off

1.8.1 Soft Switch

The soft switch is located in the lower left corner of the panel (as shown in the figure). It is recommended to use it if the instrument is used frequently. When the soft switch is in the off state, the battery still supplies power to the circuit, and the information in the memory and the time setting are saved. Some system information does not need to be reset when the system is turned on next time.

1.8.2 Hard Switch

The hard switch is located on the back panel of the instrument (as shown in the figure). If the instrument is not used for a long time, the hard switch should be turned off to better protect the instrument and battery. When the hard switch is turned off, the battery will no longer supply power to the circuit, and the contents of the memory will be reset. It must be reset when the next time it is turned on.

1.9 Battery charging

When the instrument indicates that the voltage is too low or cannot be turned on, the instrument should be charged. When charging, as shown in the figure, insert the plug of the charger into the charging socket of the instrument, and then connect the charger to the mains power of 220V / 50Hz to start charging. When the red light is on, it indicates that charging is in progress. When the green light is on, it indicates that the battery is fully charged and can be powered off. The entire charging time is about 3 hours. Be careful not to make the charging time too long. The input voltage of the charger is 220 volts AC, the output is 8.4 volts DC, and the maximum charging current is about 500 mA. This instrument uses a lithium-ion battery, which has no memory effect and can be charged at any time. The instrument can work as usual when charging.
