ERROR MESSAGES & FAULT CONDITIONS
CAUTION
If a fault condition cannot be cleared, the operator is cautioned against repeatedly
starting the instrument. In some fault conditions the internal pump may
progressively advance towards the end of its travel to clear the fault. If the end of
travel is reached in such conditions the instrument may lock up and become un-usable.
If difficulties resolving fault conditions occur the equipment distributor should be consulted.
