Additional information displayed (to be defined by the user): Model type ТКМ-459С Previous results of the measurements series, results of additional statistical processing Number of samples required to set up additional calibrations for hardness tester scales 1 or 2 Number of samples required for additional scales set up 2 to 0 (to be defined by the user) Intermediate interpolation of additional scales Piecewise linear or piecewise –parabolic (to be defined by the user) Measurement results overrunning alarm (model type ТКМ-459С only) Color. Check limits to be set up by the user for each individual scale. Types of limits: greater, less, overrun. Maximum number of measurements stored in the memory: Model type ТКМ-459С 12 400 Maximum number of individualized blocks set up in the memory: Model type ТКМ-459С 100 Displaying, statistical processing and plotting of charts of the measurement result blocks:
results in the block which are greater or less than values set up by the user results falling outside the specified range set up by the user
average deviation from the value set up by the user, number of results bigger / less than specified value, maximum deviation from specified value to bigger/less side number of results falling outside the range set up by the user (outside bigger/less limit), maximum deviation from upper/lower limit
in reference to value set up by the user in reference to measurement range set up by the user Computer interface connection: Computer interface connection USB Hardness tester automatic turn-off Turn-off time to be set up by the user Monitoring of battery charging Continuously. Continuous indication in the course of measurements Display illumination Time to be set up by the user Display color and intensity To be selected by the user Interface language of the hardness tester English ( German, French – optionally) Hardness tester power supply Autonomous, battery. Use of equivalent non-rechargeable batteries allowed. |
