Milwaukee Smart PH Meter, SM100 - Smart PH Meter Manual

OPERATION

• The meter is supplied complete with a 9V battery. Slide off the battery compartment cover on the back of the meter. Install the battery while paying attention to its polarity.
• Always remove the electrode protective cap before taking any measurement. If the electrode has been left dry, soak the tip (bottom 2.5 cm) in rinse solution (M10000B) for a few minutes to reactivate it.
• Connect the pH electrode to the BNC socket on the top of the meter.
• Make sure that the meter has been calibrated before taking any measurements (see Calibration Procedure)
• Immerse the tip (2.5 cm) of the pH electrode into the sample.
• Turn the instrument on by pressing the ON/OFF key.
• Allow the reading to stabilize before taking measurements.
• After measurements, switch the meter off and store the electrode with a few drops of storage solution in the protective cap.

CALIBRATION PROCEDURE

• Remove the protective cap from the electrode.
• Immerse the electrode tip into a new sachet of pH7 calibration solution and allow the reading to stabilize.
• Adjust the pH7 (OFFSET) calibration knob to display "7.0 pH".
• Open a new sachet of pH4 calibration solution and use a small quantity to rinse the electrode.
• Immerse the electrode tip inside the pH4 sachet and allow the reading to stabilize.
• Adjust the pH4/pH10 (SLOPE) calibration knob to read "4.0 pH".
• The calibration is now complete and the meter is ready to take measurements.
• It is suggested to recalibrate the meter at least once a month, after a prolonged stocking time and after electrode replacement.

BATTERY REPLACEMENT

When the battery becomes weak the meter will display "V".

When the low battery indicator appears, the battery has only about 50 hours of working time left. A low battery will result in unreliable measurements. It is recommended to replace immediately the battery.

Battery replacement must only take place in a non-hazardous area using an alkaline 9V battery.

Turn the meter off, slide off the battery compartment cover at the rear of the meter and replace the 9V battery with a new one. Make sure the battery contacts are tight and secure, seat the battery in its compartment and insert the cover again.
