OPERATION
Each of the 165 possible ID settings corresponds to a unique ID that is associated with CPM, refill
and discharge time values. For typical usage, only the UP/DOWN arrow keys are required to set
flow, and the ID number is provided for easy, direct return to past settings. Appendix 1 lists all pos-
sible ID settings and the default refill and discharge time settings for each CPM. Appendix 1 also
shows how the refill and dis-charge time will change within a CPM setting as you press the UP or
DOWN keys.
Sample Collection The PAUSE key (
user time to collect a sample or carry out other steps that might be difficult if the controller contin-
ued to automatically cycle and cause the pump to produce water. While the controller is cycling,
pressing the PAUSE key causes the controller to immediately enter the Hold state. Drive air is
vented from the pump (this is the pump refill cycle) and the pump fills and waits. Pressing the
PAUSE key a second time causes the controller to immediately enter the Sample state. Drive air
is directed to the pump causing the pump to discharge its volume of liquid. Bladder pumps typic-
ally hold 400-500 ml of liquid, so use of the Hold and Sample states allow the full volume of the
pump to be discharged into a sample container. Pressing PAUSE once again returns the MP10 to
its normal Automatic Cycling state. During Hold and Sample a HELD is displayed to remind you
that the controller is in a paused state. Figure 3 shows an example of the MP10 in MP mode, but
HELD in the Sample state.
Note: Pressing the Cycle key also freezes controller cycling. However, using the Cycle key rather
than the Pause key causes the startup screen to be displayed upon restart. Use of the Pause key
is recommended for typical operation.
