Gilson HM-396 User manual

(Continued on back.)
INTRODUCTION
The versatile HM-396 Load Frame can be utilized for multiple soil
tests. California Bearing Ratio (CBR), Unconned Compressive
Strength, Soil Cement, and Triaxial tests can all be performed
when tted with the required Component Set. This 10,000lbf
(44.5kN) capacity frame has a strain rate of 0.001 – 0.1 in/min
(0.0254 – 2.54 mm/min) controlled to +/- 1% of set point. Front
panel controls allow the operator to adjust the direction and
speed of the platen. The strain rate is set using the calibration
chart and the three-segment thumbwheel selector. Sliding
the cross-arm up or down the coarse-threaded 1.25in (32mm)
diameter rods and tightening the nuts makes adjustment for the
wide variety of testing components quick and easy.
FEATURES
• Precision adjustable strain rate of 0.001—0.1in/min (0.0254—
2.54mm/min) allows for multiple testing options (calibration
chart included)
• Powerful 1/8hp DC drive motor
• Load capacity up to 10,000lbf (44kN)
• Durable 14-gauge steel cabinet and precision loading screw
with protective rubber boot
• Hardened steel 8in (203mm) diameter platen accepts a wide
variety of test xtures
• Heavy 1.25in (31.8mm) diameter vertical rods with coarse threads
• Front panel controls
• Upper and lower limit indicator lights
• Three-position control switch with built-in hesitation prevents
motor damage when reversing direction
• Corrosion-resistant components
UNPACKING & SET UP
1. Inspect your HM-396 for damage, remove it from the pallet.
2. Place the Load Frame on a sturdy, level surface such as a bench
top or HMA-94 Rolling Load Frame Cart. HM-396

COMPONENT SETS
3. Connect to a properly grounded power supply with correct
voltage and amperage to output.
4. Adjust and level the crossarm to the appropriate height.
5. Install required Component Set and any accessories required
for testing.
CONTROLS
1. Main Power On/O: Includes an indicator light to show
when the power is on
2. Platen Direction: Three-position switch (up, down and o)
includes built-in hesitation to prevent motor damage when
reversing direction
3. Limit Lights: Indicates when upper and lower limits are at-
tained
4. Strain Rate: Three-segment thumbwheel selector (strain
rate calibration chart included)
5. Jog Button: Increases the speed of platen to the maximum
speed of the load frame jack screw (0.1in/min) when the
switch is pushed to the up position.
OPERATING INSTRUCTIONS
WARNING!
Disconnect and lock out power supply when servicing the
unit or installing components.
1. Read all safety and operating instructions before operating
the unit.
2. Power the unit with the Main Power switch (indicator light
will show that the unit is on).
3. Based on the calibration chart (included), set the desired
strain rate for the test using the three-segment thumbwheel
selector.
4. Use the Platen Direction and High-Speed Jog switches to ad-
just the direction and speed of the platen for testing.
5. Center the Platen Direction switch to the o position when
the test is complete.
6. Refer to ASTM and/or AASHTO test methods for specic test
instructions.
