Note
Do not attempt to run a sampler from a power source installed
on the flow meter. While a flow meter will operate satisfactorily
with a power source installed on a sampler, the reverse is not
true. The sampler's pump draws heavy current, particularly on
start-up. The flow meter-to-sampler connect cable cannot
carry such currents. If you are using a single power source for
a flow meter-sampler combination, always install the power
supply on the sampler.
Teledyne Isco offers a 4 ampere-hour 12-volt rechargeable
nickel-cadmium battery pack to power the flow meter. Teledyne
Isco packages this battery specifically for use with Isco flow
meters and samplers. Refer to the Power Products Guide accom-
panying this manual for detailed information about this battery
and the procedure for charging it.
Attaching the Nickel-Cadmium Battery – Install the battery
on the top of the flow meter case, and attach its connector to the
12 VDC connector on the side of the flow meter. Place the battery
with its cable pointing toward the right side of the cabinet.
Secure the battery by stretching the two rubber draw catches on
top of the flow meter until they slip over the two metal "U"
brackets on the ends of the battery case. Then screw the battery
connector into the top mating connector on the right side of the
flow meter case.
