|
Temperature Range
|
Operating: 32 to 104 F (0 to 40 C)
Storage: -4 to 113 F (-20 to 45 C)
Protect sample pump from weather when in use outdoors.
|
|
Compensated Temperature Range
|
41 to 122 F (5 to 50 C ) |
|
Operating Humidity
|
0 to 95% non-condensing |
|
Power
|
Three standard AA alkaline batteries
Rechargeable AA-size 1.2-volt NiMH batteries may be used but will provide approximately half the run time stated for disposable batteries.
|
|
LED Functions
|
Slow flash = normal run
Fast flash = flow fault
Double flash = low battery, approximately one-hour run time remaining
Flash every eight seconds = pump shutdown due to exhausted batteries
Indication of pump shutdown due to exhausted batteries will override all other indicators.
Four flashes every six seconds = pump shutdown due to flow fault
|
|
Run Time
(new batteries)
|
8.5 hours at 1 L/min, 25 inches water back pressure
10 hours at 2.5 L/min, 15 inches water back pressure
Dependent on batteries used. See tables below.
