    Safety Always Read and Observe the Safety Instructions! The device is constructed in accordance with the latest technology and generally accepted safety rules and regulations. Under certain circumstances, however, usage may pose risks to users or cause damage to the device. Commissioning must be carried out by specialist personnel authorized by the operating company.
  • Page 8 Safety Function Check Mode (HOLD Function) After activating configuration, calibration, or service, Stratos Pro enters function check mode (HOLD). The current outputs respond in accordance with the configuration. Operations must not be carried out while Stratos Pro is in function check (HOLD) mode, as the system may behave unexpectedly and put users at risk.

    Product Calibration Calibration by sampling – for product calibration, the uncompensated conductivity (μS/cm, mS/cm, S/m) is used. During product calibration the sensor remains in the process. The measurement process is only interrupted briefly. Procedure: 1) The sample is measured in the lab or directly on the site using a por- table meter.

    USP Function According to the “USP” directive (U.S.Pharmacopeia), Section 645 “Water Conductivity” the conductivity of pharmaceutical waters can be monitored online. To do so, the conductivity is measured without temperature compensation and is compared with limit values (see table on next page). The water is usable when the conductivity is below the USP limit.
