data at the pre-set intervals including running the pump for a preset

Press “KEY 2” to enter the time in seconds for the length of
time you wish the pump to run when taking a sample read-
ing. The pump run-time is the time in seconds for which the

point setting a pump run-time of 10 seconds if it takes 30
seconds to draw in a new sample.
