3. Millivolt mV Offset Adjustment Oxidization Reduction Potential ORP or Redox is not a precise measurement but is useful as a relative indicator mV offset adjustment makes readings comparable to a reference 1 Connect an ORP electrode and press Q as needed to select mV or R mV Dip the ORP electrode into a solution with a known mV value and stir Press when the reading is stable The primary display shows the relative millivolt value R mV while the secondary display shows the factory default mV value Adjust the R mV value using or Press or to accept or to cancel The meter allows an adjustable maximum value of 150 mV from the factory default mV value Note When an offset has been stored successfully R mV replaces mV E Ion Calibration lon 700 Only The available ION calibration values are 0 10 1 0 10 0 100 0 and 1000 parts per million ppm Choose a minimum of 2 consecutive values for calibration and prepare the corresponding ion calibration solutions For best results always begin with your lowest standard value followed by the next lowest standard 1 Connect the ISE and press e as needed to select ppm Note The primary reading will show without a stored ion calibration The secondary value is the corresponding mV reading of the ISE 2 Dip the ISE into your lowest standard solution value and stir Press when the secondary eading is stable 3 Press or to match th
