1. Calculate the sampling rate to fill a cylinder in 30 days:
2. Set the timer dials on the Z-65 to the sample rate
from step 1.
NOTE:
To obtain maximum battery life, choose
the longest time interval and the largest pump
displacement setting possible.
NOTE:
The time (18 minutes), in the chart
above, corresponds to the dial setting shown for
the Z-65 model with the timer range setting in
the factory position (jumper on the two left pins).
See section 10 Timer Range Setting, Page 24
