OPERATION:
•The meter is supplied complete with a 9V battery. Slide off the battery compartment cover located on the back of the meter. Install the battery into the battery clip connector while observing polarity.
•Always remove the electrode protective cap before taking any measurement. If the electrode has been left dry, soak the tip in storage solution for a few minutes to reactivate it.
•Connect the ORP electrode to the BNC socket on the top of the meter.
• Immerse the tip (2.5 cm) of the ORP electrode into the sample.
• Turn the instrument on by pressing the ON/OFF key.
• Allow the reading to stabilize before taking measurements.
• After use, switch the meter off and store the electrode with a few drops of storage solution in the protective cap.
• T h e m e t e r i s f a c t o r y calibrated. ORP electrodes are interchangeable and no mV calibration is needed when they are replaced.
MAINTENANCE:
•When not in use, the tip (reference junction) of the electrode should always be kept moist and safe from any mechanical stress.
BATTERY REPLACEMENT:
When the battery becomes weak the meter will display "
", the low battery indicator. The battery has about 50 hours of working time left. A low battery will result in unreliable measurements. Prompt battery replacement is required.
Battery replacement must only take place in a non hazardous area using an alkaline 9V battery.
Turn the meter off, slide the battery compartment cover located at the rear of the meter off and replace the 9V battery with a new one. Make sure the battery contacts are fully engaged in the connector, seat the battery in its compartment and replace the cover.
•The surface of the ORP electrode must always be clean. Use M10000B rinse solution for this purpose. If needed, clean the Platinum tip with very fine abrasive paper.
