8-58 Qualitek mR Owner’s Guide
chamber should be constructed so that the internal volume of the chamber
is only slightly greater than the volume of the test component. This test is
available on the Gauge Pressure Decay model Qualitek mR.
SCCM: Abbreviation for Standard Cubic Centimeters per Minute. This is a flow
measurement standardized to 68 degrees Fahrenheit and 14.7 psi (average
sea level)
Security lock: This key-operated switch locks out operators from Qualitek mR’s
Program Mode functions. The only way to access programming screens is
to use the key and turn the switch to program (vertical) position.
Sensor: Qualitek mR uses sensors to detect the quantities to be measured.
Sensor Calibration: Comparison of a device (such as Qualitek mR) to a standard
that is in turn calibrated to an even more accurate standard. Performed by
Uson.
Sensor Calibration Menu: Sensor calibration is performed by Uson.
Setpoint: A programmable threshold value (usually a minimum and maximum
value) used to establish a testing tolerance.
Start Switch: The green pushbutton.
Stop Switch: The red pushbutton. Pressing this switch will always abort a test in
progress.
Stored Programs: A set of instructions (parameters) that can be set by the
customer to run a variety of tests. There are a total of 100 programs
available. Users can alter stored programs to meet specific product testing
needs. Programs are configured in Qualitek mR’s Test Parameters Menu
and are kept in non-volatile RAM.
Supply Air: Qualitek mR’s standard fitting is a 1/8 inch female NPT bulkhead. Air
must be clean, dry, and free of oil. Unless the tester is a custom, the
maximum supply pressure must not exceed the limit shown on the back
panel label.
Test Parameter Menu: This menu is the first menu highlighted when the
Keyswitch is turned to Program mode. This is the primary menu for
entering the values that define the test and how it is to be conducted.
Test Circuit: The pneumatic tubing, fittings, valves, and sensors that make up the
internal air passages.
Test Cycle: A test cycle is all Qualitek mR-controlled testing activities that occur
from test start to finish. One test cycle can have multiple tests by linking
programs in Qualitek mR’s linking screen. Multiple tests in one cycle is
sometimes called a test series.
Test Phases: Each testing mode has individual phases or intervals of testing.
Test Port: The product to be tested is connected to the test port.
