ATH-1000 Big Load Spring Compress and Pulling Tester Meter; Spring Extension and Compression Testing Machine Functional Features: 1. Liquid crystal display (English); better Human Machine Interface (HMI) 2. High precision and resolution 3. Three kinds of measurement units can be selected (N, Lb and Kg); inter-conversion is available 4. The user can independently set up acceleration of gravity of the place of usage. In this way, the testing and unit conversion would be more accurate 5. 99 sets of test data can be stored; the user can directly look over, store and delete data in the machine 6. The user can freely shift among the following three patterns: Real-time and peak-value patterns and the pattern of automatic peak value 7. It has the function of client setup and free setup of upper and lower limits (corresponding to audible and visual alarms), storage value, holding value, automatic storage time of peak value, automatic shutdown time (non-operation), etc 8. Judgment of acceptance or rejection of test data to be printed and stored, maximum value, minimum value and mean value (only for tape printing machine) 9. MODBUS-RTU standard agreement is adopted for communication; USB interface is adopted for better connection with configuration and PLC connection Specification and Parameter: Model Number ATH- 10 ATH- 20 ATH- 30 ATH- 50 ATH- 100 ATH- 150 ATH- 200 ATH- 300 ATH- 500 ATH- 1000 ATH- 2000 ATH- 3000 ATH- 5000 Maximum testing load 10N 20N 30N 50N 100N 150N 200N 300N 500N 1000N 2000N 3000N 5000N Minimum resolution 0.001N 0.01N 0.1N Diameter of the platen 34mm 49mm 108mm Maximum free length of measurable spring 80mm 150mm 200mm Length of travel of the displacement scale 60mm 90mm 150mm Division value of the displacement scale 0.01mm Indication error ±1% Power Supply AC 110-220V, 50HZ-60HZ Power capability (without printer) 13W Power capability (with printer) 20W Working temperature 20 ± 10°C Temperature of storage and transportation -27°C~70°C Relative temperature 15%~80%RH Product Structure: ATH-1000 Force Gauge NDT à¤Ã×èͧÁ×ÍÇÑ´áç´Ö§ áç¡´
