OPERATION
User Set Mode
A final controller mode, User Set mode (MN on the display), is useful for man-
ually setting refill and discharge times on the controller as in traditional controllers (like previous
model QED pump controllers). An example of the MP10 in User Set mode is shown in Figure
8. User set mode is also used when the wells being sampled are at extreme depths or there
are other conditions where one of the 165 possible preset times of ID and MP modes will not
match your needs. MN mode is entered when the MODE key is pressed twice from the default
MP mode. As shown in Figure 8, the display indicates MN mode in the lower left corner and
CPM and ID are not displayed.

Note: changes in time settings that are entered while the controller is cycling are reflected on
the next cycle change (so a long refill time of 15 seconds will time out before a new refill time
becomes valid).
In this mode the CPM and UP, DOWN keys function differently. The CPM key becomes a key
used to scroll between the one's and the ten's digits of the ID. The UP and DOWN keys are
used to change the ID number (the MP10 has IDs that range from 1-165) up or down in value.
Sampling in ID mode is the same as explained, above, for MP mode.
Appendix 1 lists all possible ID settings and the default refill and discharge time settings for
each CPM. Appendix 1 also shows how the refill and discharge time will change within a CPM
setting as you press the UP or DOWN keys. As you change IDs you will see the CPM change
and the refill and discharge time setting change.
