    This test should be carried out by the manufacturer at its factory. Intended Use Stratos Pro A201N-CC is a 2-wire device for two-channel measurement of electrical conductivity and temperature in liquids. The device has been designed for measurements before and after cation exchangers using commercial analog 2-electrode sensors.
  • Page 7 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.
