The LXI Digital is the system of choice for both commercial and in house testing laboratories where ease of operation, accuracy and test documentation is required. During a test, the LXI displays load, stress, rate of load or rate of stress in units of time selected — plus the type of specimen and its size, all simultaneously on the indicator's four line display. At the end of a test it automatically displays both peak stress and load, and if activated, the average rate of load applied to the specimen during the test, with an accuracy exceeding ASTM C39 and E4 requirements.
The user-friendly, scroll-through test setup menu allows the operator to simply select a menu option, enter a yes or no command to activate the option or enter a numeric value to set the test parameter field. A pre-set menu lists five common specimen types to select from; cylinder, cube, beam center, beam third point and cross sectional area, allowing you to select, display and document test data.
All test information is easily read on the indicator's back-lit LCD display, consisting of four lines, each having 20 alphanumeric characters .375" (9.5 mm) in height. Test data can be displayed in any of the selectable engineering units of; Load – lbs., kN, N or Kg, Stress – psi, MPa, Kpa or kg/cm², Size – in, mm or cm and Time – seconds or minutes. A durable membrane keypad is used to select and set all menu functions.
Accuracy exceeds ASTM C-39 and E-4 requirements and in general is better than ± .5% of indicated load from 1% to full machine capacity. For hard copy test documentation, up to 1,000 tests can be stored in memory and printed directly on a parallel port printer or transferred to a PC through a standard USB port. The system also features the X-Y plotting of a load. To transfer stored test results to a PC, the optional Wincom or Wincom Plus data communications transfer program is required. The Wincom Plus program includes the added feature of allowing raw X-Y data to be transmitted directly to a PC for generating a Load/Stress vs. Time graph. Up to 10 individual graphs stored in the PC can be plotted on a single report page.
An optional piston travel speed indicator package is available, that when activated displays travel rates in either in, mm or cm per second or minute.

This is the system of choice for those demanding accuracy, ease of operation, test documentation and dependability. The iD Indicator combines an accuracy that exceeds ASTM C-39 and E-4 requirements and in general is better than ± .5% of indicated load from 1% to full machine capacity with a construction designed for the harshest of laboratory applications. All information is clearly displayed on the indicators 4.6" w x 3.4" h (116 x 86 mm) back-lit VGA graphic panel display. Its 320 x 240 pixel screen with adjustable contrast is easily readable in both bright and poor lighting conditions.
During a test, the iD simultaneously displays load, stress and rate of load in the time units selected. At the end of a test it automatically displays peak stress and load, and if activated, the average loading rate applied to the specimen during the test. Large alphanumeric characters display test data in any of the selectable engineering units, force units of lb, kN, kg and N, stress units of psi, MPa, kg/cm2, Kpa, size units of in, mm, cm, and time units of seconds or minutes.
Its user-friendly setup menu displays all menu option listings simultaneously, allowing the operator to quickly access the required option, and simply press a key to activate it or enter a numeric value to set the test parameter. This display feature eliminates the time consuming method of scrolling through single line menu
displays to find an option or set a function. Its sample type menu lists six common specimen types to select from; cylinder, cube, beam third point and center point, cylinder split in tension and cross-sectional area. Just select and set. Test results can be automatically stored for hard copy documentation.
For test documentation the indicator can be set to automatically store test results for downloading via RS-232 to a PC or for printed reports. Up to 500 tests can be stored to memory and printed in a spreadsheet format. Information includes: Test date and time, sample ID number, sample type, specimen area and length, peak load and peak stress. Optional data includes average rate of load applied to a specimen during a test, cylinder correction factor to C-39, cylinder break type, cylinder cap type, sample age and weight, and operator ID number.

This is a basic, easy-to-use, budget-minded load indicator. The DIR model simultaneously displays both live load and rate of load in force units per second during a test and peak load automatically at the end of a test.
The DIR is one of the easiest-to-use digital load indicating systems available, featuring automatic test reset—eliminating the need to zero between tests—and automatic peak-load display at the end of a test through the pre-set sample-break detector function. The digital's face is set on a 60º angle for easier reading of load values, and the display uses 3/8" (9.5 mm) characters protected by a non glare, scratch-resistant window. Users can select from load-value engineering units of lbs., kN, kg, and N. Designed for years of dependable service, the digital's tactile keys have a life cycle of greater than two million uses, and accuracy is ±.5% of indicated load from 1% to 100% of machine capacity, exceeding ASTM C39 and E4 requirements. The calibration program is password protected in permanent, non-volatile memory. The DIR digital has no hardcopy test documentation capabilities.
