3.2 CONTROLS AND ADJUSTMENTS (See Figure 3-2.)
SENS A single turn control used to set the threshold
sensitivity level above the ambient noise pickup.
RANGE A dual in line (DIP) switch located within the
enclosure (see Figure 3-3 and Table 3-1) which is
used to program the module to accept an input
SPAN A multiple turn adjustment which is used to set
the voltage output signal to the desired span
corresponding to the equivalent flow range (i.e., 0
to 5V corresponding to 0-100 GPM).
ZERO A multiple turn adjustment which is used to set
out put signal with no flow to the desired “zero”
value (i.e., 0.00V dc).
RESPONSE A multiple turn adjustment which is used to set
the response time of the analog output.
