FUSE, A circuit protection device located inside of case
(see paragraph 3.2.1)
SENS. A multiple turn control used to set the threshold
sensitivity level above the ambient noise pickup.
RANGE A dual in line (DIP) switch located on the PCA61
board (see Figure 3-3 and paragraph 3.2.2.) which
is used to program the module to accept an input
frequency range.
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
output signal with no flow to the desired “zero”
value i.e., 0.00 Vdc).
RESPONSE An internal, multiple turn adjustment which is used
to adjust the response time of the analog output.
3.2.1 Replacing the Fuse (see Figure 3-2)
1. Turn off power to the FLSC-35B.
2. Remove the two screws from sides of case.
3. Lift off cover and remove printed circuit sub-assembly.
4. Pull fuse from fuse socket using fingers pliers are not
recommended).
5. Install now fuse.
6. Reassemble into lower case.
3.2.2 Range Select for Analog Output
1. Turn power to FLSC-35B off.
2. Remove the two screws from sides of case.
3. Lift off cover and remove printed circuit sub-assembly.
4. Turn “on” desired range position using a ball point pen or
similar object (Refer to Figure 3-3 and Table 3-1).
5. Reassemble into lower case.
SECTION 4 CALIBRATION OF ANALOG OUTPUT
4.1 INTRODUCTION
In general, all flow measurement systems supplied by OMEGA
Engineering ˆˆhave been factory calibrated as specified by the
user, at the time of purchase.
Field calibration is only required when a change has occurred or
is sought to the measuring system. Such a change may be due to
repair, replacement or recalibration of the flowmeter, or perhaps
a change in the analog output span.
