Real-Time Displays As the sampler runs a sampling program, it displays the program’s status.
The status display may include such information as the time of the next
sample, the number of the next bottle, or whether the sampler is disabled or
stopped. If the sampler encounters an error while running the program, it
displays a message alerting you to the problem.
Programming for Modules Program the modules from the sampler’s control panel. The module’s
program settings become part of the sampling program.
Setup for SDI-12 Sondes Calibrate and program SDI-12 sondes from the sampler’s control panel. The
program settings become part of the sampling program. See Section 6.
Memory for Stored Programs
and Readings 512 kilobytes of battery-backed RAM (Random Access Memory), to store:
•Five sampling programs.
•A sampling report from the most recently run program. It records as many as
1000 sampling events; events can be the program start time, enable time,
sample event information, etc.
•700 Series module readings. The readings can be: level, flow rate, velocity, pH,
temperature, or the data collected by the 4-20 mA module.
•Rain gauge and refrigerator temperature readings.
•SDI-12 sonde readings.
Five Reports Available
•The Program Settings report, listing current program settings.
•The Sampling Results report, listing the events occurring during the program.
•The Combined Results report, combining sampling events with readings from a
rain gauge, module, or SDI -12 sonde.
•The Module Summary report, summarizing flow rate or parameter readings.
•The Rainfall Summary report, listing a summary of rainfall readings.
Serial Data Output
ASCII data output from the interrogator port.
Units of Measure A variety of metric and English units of measure for length, flow rate, flow
volume, and temperature.
External Sampler Enable Teledyne Isco flow meters and flow loggers have a programmable sampler
enable feature that lets them send an electronic signal to a 6712SR that
enables (starts) or disables (stops) a running sampling program.
Dual Sampler Mode Dual Sampler Mode operates two samplers.
Command Driven Operation
Operate sampler functions using RS-232 communications.
Warning Messages
•Pump Tube Warning. The 6712SR displays a warning to inspect the tube.
•Internal Battery Warning. From the Maintenance screen, the 6712SR displays a
warning when it is time to replace the internal battery. The internal battery
preserves stored data when the 6712SR is without external power.
