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 ow transducer output at known pressures and ow rates.
Calibration Screen — Calibration allows comparison of the Isaac to pressure and ow
standards. The calibration screen shows the Isaac’s actual reading and the pre-pro-
grammed target value the technician compares to the pressure of ow standard. Only
qualied 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 elds on the Main screen.
Counters, (Reset) — By selecting the “Cycles” or “Failures” numeric elds, 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 xtures 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 xtures. Coupling pres-
sure must be the same as line or test pressure specied 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 lled with air. Coupling time gives xtures 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.
