Convenons Used Throughout This Manual
The following convenons are used in the manual to describe the Console, instruments, and operaon:
• Calibraon - The process of using a known force or angle to adjust the instrument parameters so that any
arbitrary force or angle input can be accurately determined.
• Control Sck - The singular mul-axis buon on the Commander Echo Console, which can be moved up,
down, le, right, and pressed, in order to operate the Console.
• CV - The coecient of variaon (CV) is dened as the rao of the standard deviaon (σ) to the mean (μ), or
in mathemacal terms, CV = σ / μ. In probability theory and stascs, CV serves as a normalized measure
of variability to help describe the relave scaer or spread of a data sample. A smaller CV suggests a higher
level of consistency. A calculated CV less than 15% (0.15) is oen used as an indicator of consistent eort
by subjects during biometric strength tests. This value is displayed in the review screen of the Console.
Commander Echo calculates CV using populaon standard deviaon. Note that this diers from CV
calculated using the sample standard deviaon, which can give a very dierent result.
• Device - Refers to both the Commander Echo Console and any Commander Echo instrument.
• Exam - This term is used to refer to a group of tests performed with the same instrument.
• Hold - Indicates that the Control Sck should be pressed and held.
• Instrument - This refers to a JTECH Medical tesng device, used in conjuncon with the Commander Echo
Console to record test data.
• Press - Indicates that the Control Sck should be pressed and released.
• Repeon, or Rep - A single instance of measuring performance for a designated instrument.
• RF - Radio Frequency.
• ROM - Range of Moon.
• Side - Either le or right, noted as L and R, respecvely.
• Test - Used to refer to a group of repeons performed for one or more sides with a given instrument.
• Threshold - The minimum force or angle that must be exceeded to start or end a repeon.
• Zero or Zero Calibraon or Set Zero - The process of determining the instrument parameters when no force
or angle is applied to the instrument
Convenons Used Throughout The Console Menus
The following addional convenons are used throughout the Console menus:
• Cal. - See Manual convenon Calibraon.
• CV% - See Manual convenon CV (Coecient of Variaon).
• DEF% - Percent Deciency, a value calculated from test informaon and displayed in the review screen.
• DEG. - Abbreviaon on the Console for degree.
• DEL. ALL - Abbreviaon on the console for Delete All. A global funcon that deletes all test data.
• DIFF. - Abbreviaon on the Console for dierence. A calculated value for the Maximum angle.
• FAT% - Fague Percent, a value calculated from med test informaon and displayed in the review screen.
• INC - Abbreviaon on the Console for Inclinometer.
• MMT - Abbreviaon on the Console for Manual Muscle Tester.
• Press any key - Indicaon to press the Control Sck in any direcon or into the console.
• Press Enter - Indicaon to press the Control Sck into the console.
• PRI. - Abbreviaon on the Console for Primary Inclinometer.
• POS - Refers to the calibraon posion for the Inclinometer.
• Ready Time - Starng delay before a test rep begins recording data, this is used to ensure transient forces
are not recorded.
• REPS - See Manual convenon Repeon.
• REV - Revision. Hardware Rev is specied on Device label. Firmware REV is noted in the informaon screens
• SEC. - Abbreviaon on the Console for Secondary Inclinometer.
• SFG - Abbreviaon on the Console for Stac Force Gauge.
• SN - Serial Number also referred to as device ID#.
• WT. CT - Weight Count. Instrument reading of a known physical value which is not neutral or minimal.
• Zero CT - Zero Count The value of a force or angle input when the instrument is neutral or equal to zero.
