Leak Zero:
The leak transducer is sensitive and it’s zero point may shift if it
is overloaded. The instrument is able to tolerate this to a large degree, but
eventually may stop with a fault. MEWS may be used to give a warning
before the instrument fails.
o
Calibration Due:
it is recommended that the calibration of this instrument is
checked annually, or as often as your quality system demands. This value is a
display of the number of days left before calibration is due. If the value is
negative then calibration is over-due.
