Step 4 - Reset Totalizer; Step 5 - Sampler Pacing - Teledyne 4250 Installation And Operation Manual

2.4.7 Step 4 - Reset Totalizer

2.4.8 Step 5 - Sampler
Pacing
If you select step 4, the following will appear:
RESET TOTALIZER
• YES • • NO •
This step allows you to reset the flow meter's internal flow total-
izers. All models have the capability of maintaining a separate
totalizer for the time the sampler is enabled through the
sampler enabling feature (step 6). The 4250 flow meter,
because it can measure forward and reverse flows, maintains
three separate totalizers: a separate totalizer for each
direction and a totalizer for the difference between forward
and reverse flows.
If you select NO, the flow meter will advance to the next step. If
you select YES, the flow meter will reset the internal totalizer to
zero.
FLOW TOTALIZER: XX CF
FORWARD XX REVERSE X CF
Then, if you have sampler enabling turned on (step 6), the flow
meter will ask you whether you want to reset the totalizer for the
total flow during the time the sampler was enabled. (See step 6
for an explanation of sampler enabling.)

ENABLE TOTALIZER
PRESS 'ENTER
Then:
RESET SAMPLER ENABLE TOTALIZER
• YES • • NO •
If you select step 5, the following will appear:
SAMPLER PACING
• DISABLE • • (VOLUME) • • (FLOWLINK) • • CONDITIONAL •
This step determines how the flow meter will signal an asso-
ciated automatic wastewater sampler to take a sample. The flow
meter and sampler must be connected together with a cable. The
flow meter sends flow pulses to the sampler. The sampler uses
these flow pulses as counts. When an appropriate number of flow
pulses has been received by the sampler, it will take a sample.
VOLUME will not appear if the flow meter is measuring level
only, or is only being used for parameter monitoring.
The Flowlink menu option will not appear unless Flowlink
software is installed and pacing has been downloaded from
Flowlink.
If you select DISABLE for sampler pacing, the flow meter will be
effectively disconnected from the sampler. The sampler will run
its program as if there were no flow meter. Selection of DISABLE
