Calibration
— Comparison of a device (such as the Isaac) to a standard that is in turn
calibrated to an even more accurate standard.
Calibration Data
— Values entered into Isaac through software calibration. Calibra-
tion data is stored as a look-up table in the Isaac’s non-volatile RAM and is used to
linearize pressure and flow transducer output at known pressures and flow rates.
Calibration Screen
— Calibration allows comparison of the Isaac to pressure and flow
standards. The calibration screen shows the Isaac’s actual reading and the pre-pro-
grammed target value the technician compares to the pressure of flow standard. Only
qualified technicians who have proper training and resources should calibrate the Isaac.
Counters
— The Isaac records the total number of tests performed (both pass and fail)
and the number of rejects (fail only). Running totals are displayed in the Test Cycles
and Failures fields on the Main screen.
Counters, (Reset)
— By selecting the “Cycles” or “Failures” numeric fields, the “Reset
Counters” dialogue box will appear, press the clear button then press “OK”.
Coupling Port
— The coupling port supplies air pressure to product sealing fixtures or
other external pneumatic components. Generally, the port labeled “2” on front of Isaac
is used for coupling air output.
Coupling Pressure
— The air pressure supplied to external fixtures. Coupling pres
-
sure must be the same as line or test pressure specified by the customer at order un
-
less additional pneumatic components are added.
Coupling Time
— A delay timer used to apply a clamp or seal to product under test
before the product is filled with air. Coupling time gives fixtures enough time to seal
product before Isaac applies test pressure.
D
Decay
— The amount of pressure a product can lose during a test period before going
out of an established tolerance. Also called pressure drop.
