Safety Precautions
1. The complete instruments may not be immerged into water either be exposed to rain. This could lead to unpredictable damages. The accumulator or display could be destroyed.
2. If the instrument is not used for a longer period of time, it should be stored cool and dry, the best in its original package. The environmental temperature should be from -30°C up to +80°C and relative humidity at (RH) 5% up to 95%.
1 General Description
1.1 Features
LCD display of 128×64 matrix is used. Converts to all common hardness s cales (HV, HB, HRC, HRB, HRA, HS). English displaying and menu operating, the operation is easy and convenient. With RS232 interface, multiple communication modes are adopted to meet cus-
tomized requirements of various users.
Equipped with 7 types of impact devices which need not to be recalibrated when
changing them, the system can identify the type of impact device automatically.
Max 600 groups（imp act times: 32～1）of data can be stored at internal non-
volatile data storage.
Upper and lower limit of hardness can be pre-set; If the tested value exceeds the
limits, alarm will be sent out automatically to make convenient for the require­ments of batch measurements.
Back light display has been used to make convenient for the use in poor light. Test values software calibration function. Material of “cast steel” is added; HB values can be read out directly when D/DC
impact device is used to measure “cast steel” work piece.
Printer be separated from main unit and copies of testing results can be printed
as required.
Power is two of AA battery. Continuous working period: approx. 200 h (no back
light on).
Software of PC can be installed according to the requirements of user, the fun c-
tion will be more powerful to satisfy the more strict demands of quality control and management.
1.2 Main Application and Testing Range
1.2.1 Main Application
The assembled machinery and permanently installed parts Die cavity of molds Heavy work piece Failure analysis of pressure vessel, steam turbo-generator set and other equip-
ment
Narrow testing space where work piece installed Bearings and other parts Cases which require the test result with normalized original recording Material identification of the metal material warehouse Quick tests of large range and multipoint measuring positions for heavy work
piece
