Note: When the coupling fluid falls below its recommended
minimum level, air bubbles may be introduced into the coupling
fluid, which reduces the accuracy or precision of source plate
surveys and fluid transfers. Labcyte recommends that you refill the
coupling fluid bottle as soon as possible after the Warning light
has been turned on (see
page 6-8).
The coupling fluid temperature is outside of the normal range:
