These ‘Equipment Maintenance’ posts are intended to show how to service and perform basic maintenance of different VJ Tech equipment used
for consolidation testing. This post describes how
to remove, check and replace the battery on a PCB. This may be when the battery has failed or following a prolonged period where the
instrument has been switched off in humid conditions and will not power up.
Consolidation Testing Part 1 described the initial setup for a Consolidation Test involving the System Setup and Test Creation
using an Automatic CONSolidation (ACONS) Instrument. Consolidation Testing Part 2 will deal with the Test Execution and Results.
These ‘Using Clisp Studio’ posts are intended to highlight facilities in Clisp Studio that the User may not be aware of, or general facilities to help
testing run smoothly.
The California Bearing Ratio (CBR Test) is a penetration test for evaluating
the load-bearing capacity of soils used for building roads and other hardened surfaces. The traditional method of for a CBR Test involved penetrating a
plunger of fixed diameter into a soil sample using a Load Frame (usually controlled by some mechanical device) with a Load Ring for measuring Vertical Load
and the Displacement measured using Mechanical Dial Gauges. This required the laboratory technician to be on hand with a clipboard and datasheet(s) to
record the data when required throughout the Test.
These 'Equipment Maintenance' posts are intended to show how to service and perform basic maintenance of different VJ Tech equipment. This post describes
how to attach the ACONS earth lead should it prove necessary and how to adjust the screen contrast on the ACONS and other various VJ Tech Instruments. This
may be necessary if the screen is too bright or too dark.
– Part 1 will describe the initial setup for a Consolidation Test involving the system setup and test creation using an Automatic CONSolidation (ACONS)
Understanding shear strength is vital to the engineering properties of any structural project. Shear testing determines the strength of a material and records the specific
strains a substance can take allowing the technician to understand how the sample will ‘behave’ in its relative field.
Welcome to part 3 of our Clisp Studio user guide. To get the best performance from our advanced software you must become familiar with all
the facilities in Clisp Studio to help your testing run smoothly.
Part One of our Triaxial Testing guide described the initial setup for a
Triaxial Test involving the System Setup, Sample Preparation and Test Creation. Part 2 described the setup required for the Saturation, Consolidation and
Shear stages. Triaxial Testing Part 3 will describe the Test execution, monitoring and results manipulation and assumes that all 5 setup
steps of the ‘Assistant’ have already been completed.
Equipment maintenance checks are vital to ensure the risk of potential problems is significantly reduced. Part three explains how to replace the internal Ram ‘O’ Ring in a standard Triaxial Cell, as well as one fitted with an internal load cell.
