(position) readout should not be used as the primary strain measuring device where an extensometer on the specimen is clearly warranted. Frame compliance can be accounted for, to some extent, by Instron software. 10.At speeds below approximately 0.1 mm/min (0.004 in/min) the hydraulic cylinder moves in increments approximately equal to these values and can be seen as load steps depending on the specimen stiffness and load range.

Chapter 2: Specifications Noise level The A-weighted emission sound pressure level generated by the testing system under normal operating conditions does not exceed 70 dBA. The peak C-weighted instantaneous sound pressure value does not exceed 63 Pa. Since many variables (such as room layout) affect noise levels, it can not be assumed that these readings will be equal to those in the field.

Some bolt patterns are designed for the mounting of specific standard Instron accessories or fixtures, while others are more general for the mounting of a wide range of standard Instron accessories or fixtures. Any bolt pattern can be used for the mounting of customer fixtures; appropriate adaptation may be necessary.
Chapter 3: Operation Start the system This document presumes that customer training (by Instron service personnel) has been completed and that at least one procedure has been created in the controlling software. Before operating the system: • Familiarize yourself with the operating features and controls described in these instructions and in all other accompanying documentation for the controlling software.

Any fixture or specimen installed in the frame may not align. • If the crosshead is positioned with the crosshead lift cylinders fully extended and a tension or compression load is applied, the crosshead could slip until it reaches a level position. Product Support: www.instron.com...
Chapter 3: Operation • If the crosshead is positioned with the crosshead lift cylinders fully retracted and a tension load is applied, the crosshead will not be able to absorb the shock generated by a specimen break. This will cause the shock to be transferred to other components of the frame and may cause damage to the frame.

Chapter 3: Operation Do not attempt to use the Jog controls to operate the hydraulic cylinder until approximately 1 minute has passed. This allows the HPS to build enough pressure to clamp the crosshead lock cylinders. The noise level of the HPS is a good indication of when this occurs; the noise level will decrease once it has built enough pressure and the crosshead lock cylinders are clamped.

Chapter 3: Operation Shut down the system It is recommended that the system as a whole (frame, control unit, HPS, computer system, peripherals, etc.) be shut down at the end of each working day or anytime it will sit idle for long periods of time. The procedure to shut down the system is as follows: 1.
On loss of power, when the servo blocker valve closes, the hydraulic cylinder will drift upward approximately 2 mm (0.08 in). Any instrument in the load train that is sensitive to a tensile load may be damaged (i.e. extensometers, low range load cells, etc.). Product Support: www.instron.com...

General maintenance recommendations Only the maintenance procedures outlined in these instructions should be performed by the customer or their representative. All other maintenance and repairs should be performed by Instron Service personnel only.
Chapter 4: Maintenance Preventative maintenance schedule Table 13 outlines a recommended preventative maintenance schedule for system components. Table 13. Recommended preventative maintenance schedule. Frequency Component Maintenance Task • Daily: System Make daily checks of system; see page 53. • Monthly: Visually inspect all hoses (exposed and hidden) and around the base of System the frame and HPS for signs of oil leakage.
If any of these checks reveal a potential problem, the problem should be investigated and corrected before the system is operated. For assistance in troubleshooting the system, contact your local Instron Services department as directed on page 18.
Chapter 4: Maintenance Remove and install console covers To perform any maintenance on the HPS it is necessary to remove the rear cover from the console. Loosen and remove the seven M6 button head cap screws (2, Figure 11) from the rear cover (1). Be careful of the electrical wires to the fan.
HPS. Tighten any loose connections that you may find. • Inspect all cables for deterioration. Check for abrasions, cuts, etc. Replace cables as necessary. If you notice any problems resulting from this inspection, contact your local Instron Services department as directed on page for immediate assistance.
Chapter 4: Maintenance a short period of time is abnormal; contact your local Instron Services department as directed on page for immediate assistance. • Clean the rod of the hydraulic cylinder. Completely extend the hydraulic cylinder and wipe the rod with a soft cotton cloth to remove oil residue and debris.
