INTRODUCTION
The COMTESTinstrument provides:
•Data monitoring and capture of load signals for:
•Compression range 0 to 3000 KN
•Flexuralrange 000.00 to 100.00 KN.
•0 ~ 200 millivolts transducerrange
•+6 and -4 volts DC excitation provided
Transducerconfiguration, calibration and Linearisation facilities forCompression and
Flexuralinput ranges.
Data logging: up to 100 test results, timestamped and with all relevant test data
results.
RS232 Serialcommunications portforprinting test results information, with options
available forfull computercontrolorand remote monitoring
This is achieved by the micro-processorbased electronics which includes:
16 bit multi-channelADC with automatic programmable gains.
RS232-C serialport, configured as 9600 baud, 8 bits, 1 stop and no parity,
fortest printout ordumping the results directly to a computer
4 rows *20 columns LCD, dot matrixscreen, with full LED backlight.
16-key pad forinstrument set up, usage and control.
Built in battery backed real-time calendar/ clock device.
Non-volatile memory, forconfiguration and data logging purposes, resulting in
storage forup to 100 test results.
