nected to the optional digital cellular modem), or from a 581
Rapid Transfer Device (RTD). The RTD is a quick and simple
way to transfer the data from the field to your computer. Reports
are easily collected with Teledyne Isco’s Samplink software.
1.5 Pump Requirements The pump also requires a pump tube made specifically for the
6712 and 6700 Series samplers. These pump tubes are easily rec-
ognized by their blue alignment collars. The 6712 pump tubing is
the same as that for Teledyne Isco’s 6700 Series samplers, but
different from Teledyne Isco’s earlier model samplers, such as the
3700 Series. Other types of pump tubing will not work in
the 6712FR. Refer to Replacing the Pump Tube on page 8-9.
CAUTION
This sampler has a high performance pump. As with all such
pumps, it relies upon liquid to cool working components. If the
sampler is programmed to pump in the absence of liquid in
excess of 5 minutes, excessive heat buildup may damage the
paddles, rollers, and housing. Ensure that the liquid inlet is
completely immersed.
