Gilson HM-382 Operating Manual

HM-382 & HM-382F Digital Pneumatic Direct
INTRODUCTION
The Gilson model HM-382 Digital Pneumatic Direct
Shear Machine is a tabletop unit that provides direct or
direct/residual shear values for evaluating the strength
and stability of soils. This device utilizes a pneumatic
loading piston for applying the vertical load to the sam-
ple. A calibration chart is included for setting the high
load or the low load via the Fairchild Regulator while a
built-in digital readout displays the vertical load in psi.
This Direct/Residual Shear Device has a strain rate
of 0.0001 – 0.3 in/min (0.0025 – 7.62 mm/min) with a
maximum shear displacement of 0.8in (20.3mm) and
the travel speed is set with the thumbwheels on the left
side of the unit. The residual shear force is determined
by a load cell and while real time load settings and
peak load are displayed on the digital readout. Con-
solidation and shear displacement are measured with
Displacement transducers and displayed on a digital
readout.

UNPACKING & SETUP
• Inspect your Direct/Residual Shear Machine for
damage, remove from the pallet.
• Place Direct Shear Machine on a sturdy, level sur-
face, such as a bench top or Model HMA-95 Rolling
Cart for Shear Machines.
• Review the Connections section and install neces-
sary components.
