  • Page 37: Measuring Sample Volume

    The volume is determined by the programmed value. The volume is dependent on the volume per revolution of the pump, which is dependent on the suction head. The 6712SR delivers the sample by counting the pump revolutions and automatically compensating for the suction head.

  • Page 38: Installing The Sampler

    CAUTION When using the 6712SR sampler with a 750 or 710 module, transmitters such as cell phones or walkie talkies must not be operated within 3 meters of the sampler. If water level readings are fluctuating due to TV/radio station transmitter towers in the area, the sampler must be relocated.
