ORP/REDOX Overview ORP stands for Oxidation / Reduction Potential and represents the oxidizing or reducing nature of a solution. The overall “reactive” tendency of a solution can be determined from ORP measurements. ORP testing is becoming increasingly more common in waste-water measurement regimens. The unit of measurement for ORP is mV. Replacing Electrodes TM The ExStik is shipped with an electrode attached. If the electrode is to be replaced, follow these steps for removing and connecting electrodes.
Changing the Displayed Temperature Units o o Press and hold the CAL button for approx. 3 seconds. The C or F icon will change first and then the numerical temperature value will change after the button is released. If the Calibration mode is accidentally accessed (‘CAL’ appears on the LCD) simply turn the TM ExStik off and start again. ORP Operation TM When an ORP electrode is connected and the ExStik is turned on, it enters the Automatic Calibration mode.
Battery Replacement 1. Twist off the battery compartment cap 2. Replace the four (4) SR-44 button batteries observing polarity Rear TM Top View of ExStik Front (LCD Side) 3. Replace the battery compartment cap Battery Note: For maximum battery life, use battery style SR-44 (Silver Oxide) such TM TM Energizer No. 356 or Duracell No. 303/357.
Measurement and Display Considerations • • • If the unit appears to be locked (display frozen). It is possible that the Data Hold mode has been inadvertently accessed by pressing the MODE button. Simply press the MODE button again or turn the meter off and restart if the display appears frozen. If the meter does latch up and no button presses revive it, remove the batteries and restart. Note that if the batteries are removed, any stored readings will be discarded.
