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.
Display on LCD Explanation
SAMPLER READY
04/30 04:30:02
This display shows the sampler is ready to program. It displays the
current time. From here the user can enter any TIME, FLOW, or
* Mode. Press the * key to access the * Mode.
ENTER * MODE?
__ __ 04:30:02
Prompts the user to enter either a program or a * Mode. Press 19
and <ENTER> to proceed.
0=MAINTAIN 1=CLEAR
__ 04:30:02
This prompt is asking the user to determine how the system will
handle the current accumulation of revolutions:
0 - This maintains the current revolution count. This is useful if
the operator wishes to increase the number of revolutions the
current tubing can accumulate before a tube life warning is
issued. For example, assume the current tubing has 200,000
revolutions. The operator really wants the warning to come
on at 400,000. The 0 key would be pressed instead of 1 to
maintain the history the tubing has already generated. The
user would then enter 0400 (for 400,000) at the TUBE LIFE
WARNING prompt (see below).
1 - This resets the current revolution count. This is necessary if
the user is going to be placing brand new tubing into the
system. With the counter reset the user knows exactly how
many counts it will take for the sampler to issue a warning to
change the tubing.
