The Precise Digital Controller is designed for
manual or servo-equipped tension and com-pression
testing machines. It is a presettable
unit that simplifies materials testing and re-quires
a minimum amount of training. The Pre-cise
features load, crosshead position and
strain inputs plus enhanced closed-loop servo
capabilities for accurate and repeatable test-ing.

• plastics
• film
• textiles

• nonwovens
• rubber
• adhesives

• metals
• wire
• plus a variety of products.

Standard Features:

• Indicate load, load rate, position, position rate, strain, strain rate.
• Plot load, position or strain real-time.
• Save and recall three test procedures for accurate and repeatable testing.
• Password protected supervisor/operator modes al-low test procedures to be locked under password so they cannot be changed inadvertently.
• Calculate key test parameters such as Peak Load/ Stress, Offset Yield, Yield EUL, Modulus of Elastic-ity, Percent Elongation at Break and more.
• Calculate high, low, mean and standard deviation for a group of tests.
• Store up to 350 test results per test procedure to permanent memory. Test results include Date, Time, Specimen ID#, Specimen Area and Length plus all calculated test parameters.
• Generate hardcopy printouts of Group Test Reports and Single Test Reports which include an XY plot on an HP PCL5 compatible printer (ie.HP Deskjet/ LaserJet).

• Use the WinCom Plus Data Communications Program to download test results and XY data to a remote com-puter for import into common spreadsheet and data-base programs. Plot multiple test curves on the same set of graph axes.
• Configure up to a 3 segment control profile with soft-ware selectable control channels that can be changed on the fly. Includes PID compensation.
• Integral emergency stop and start pushbuttons on servo equipped units.
• Select between English, Metric and SI engineering units.
• Calibrate up to 6 load cells and 6 extensometers with piecewise linear fit between points for maximum ac-curacy. All calibrations are password protected.
• Calibrations exceed ASTM E4/E83 accuracy require-ments and feature high resolution and fast sampling rates in a simple proven design.
• Includes signal conditioning and excitation for a strain gauge load cell, pressure transducer or extensom-eter and a digital position encoder. Optionally, an LVDT conditioner can be supplied for AC extensometers.
