*19 Pump Tube Utilities
*19 resets the tube life pump count. A peristaltic units ability to operate and perform to specifications, such as
transport velocity and lift height is, to a certain extent, determined by the medical grade silicone rubber pump
tubing used in the system. The characteristics of the tubing change as it wears. It becomes less resilient, less
able to maintain its shape, develops pinch points on the outside edge of the tube, and as such is not capable of
the performance it had when it was new. To maintain optimum performance, it is necessary to monitor the
wear on the tube. *19 does this by enabling the operator to set a maximum number of pump revolutions, the
tube currently in use, will be allowed to withstand. This, in effect, determines the tube’s useful life. Manning
recommends not exceeding 1,000,000 pump counts for a singular tube as, by this time, there is risk that the
tubing could fail causing a variety of problems. *19 should be used every time the pump tubing is changed.
The user will be alerted to change the tubing, when the tubing reaches the number of counts set. The warning
will appear, every time the user executes a Program Mode, by pressing <START>. Since all programs are
initiated by pressing <START> the warning will always appear, if appropriate, before the program is initiated.
This allows the user the opportunity to exit the program and change the tubing. Once the tubing is changed,
the user can re-enter the program and begin sampling.
When the pump tubing is to be changed, the user will enter into *19 Mode, just like entering any of the other *
Modes. The sampler will prompt the operator to clear the current pump count by pressing 1, or to maintain
the current count by pressing 0. It is advisable to reset the pump counts when changing the tubing so an
accurate accounting of the number of revolutions, the tube in the pump has experienced, can be obtained. At
this juncture the user will be asked to enter a number for the tube life warning which represents the number of
revolutions the current tube will be allowed to accumulate before a warning is issued. Once entered, the
system will return to the sampler ready prompt and the system will be ready to program.
