The load circuit must be fused for the maximum relay current, in order to prevent the output relay contacts becoming welded in the event of a short circuit. Do not connect any additional loads to the screw terminals for the supply of the instrument. Any electrical connection other than that specified in the connection diagram may result in the destruction of the instrument. -

Page 41: Calibration
8 Calibration 8.1 General The cell constants of conductivity cells stray somewhat depending on the type and additionally change during operation (due to deposits such as lime, or as a result of wear). This results in a change of the output signal from the cell. It is therefore necessary that the user is able to compensate for the deviations of the cell constant from the nominal value, either by manual entry or an automatic calibration of the cell constant K…

Page 42: Activating The Calibration Mode
8.2 Activating the calibration mode The setup interface and the measurement inputs for conductivity and temperature are not electrically isolated. This means that, in unfavorable conditions, equalizing currents may flow when the PC interface is connected. These equalizing currents may result in damage to the devices connected.
