Micro purge MP15, User Manual

OPERATION

18

In User Set mode the CPM and UP, DOWN keys function differently 
than MP mode.  The CPM key becomes a key used to select the digits 
of the refill and discharge time settings found at the rightmost positions 
on the display.  The UP and DOWN keys are used to adjust the digit 
value up or down.  By selecting and adjusting digits up and down a user 
can quickly set any time from 00.1 seconds to 99.9 seconds.  Sampling 
in User Set mode is the same as explained, above, for MP mode.

The MP15 does not attempt to translate a user set time into a corres-
ponding ID or CPM.  Also, any settings you have entered in MP or ID 
modes are lost once you press the MODE key to enter MN mode.  

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 sec-
onds will time out before a new refill time becomes valid).

MP15 Battery - 

The MP15 features sophisticated power-supply 

circuitry that optimizes battery life.  A fresh set of AA batteries will 
provide more than 100 hours of controller operation at normal operating 
temperatures.  As ambient temperatures drop below 15-20F (-9C to 
-6C), the ability of  the  alkaline batteries to deliver energy is affected.  
Continuous operation may be difficult in extremely cold conditions.  
Once the batteries and MP15 warm, additional cycle capacity will be 
regained from a set of batteries. drop below 15-20F (-9C to -6C), the 
ability of  the  alkaline batteries to deliver energy is affected.  Contin-
uous operation may be difficult in extremely cold conditions.  Once the 
batteries and MP15 warm, additional cycle capacity will be regained 
from a set of batteries.

Replace alkaline batteries by removing the 4 thumbscrews located on 
the battery cover and inserting 3 fresh cells.  The MP15 battery holder 
includes space for 

3 spare AA cells

 so you should never be without 

power in the field.  Properly dispose of the spent alkaline cells.

Note: If you are storing the MP15 for more than 3 months, remove the 
AA batteries to prevent leakage.  The MP15 power supply is auto-
matically shut off by closing the lid. Make sure the lid is closed during 
storage
