To replace electrolyte solution

Replace the electrolyte solution when bubbles are seen around the sensor

or membrane, meter appears to be less sensitive, or when an error message

indicates that measurements are inaccurate.

1. Remove the screw nut, washer, and o-ring from the filler port with a screw driver.

2. Flush out the current electrolyte solution.

3. Rinse the electrode by injecting distilled or de-ionized water into the filler

port. Gently shake the probe and flush out the water.

4. Use a syringe to refill the probe with electrolyte (KBr) solution from the

sprue on the probe. Refill slowly to ensure no bubble in the probe.

5. Reinstall the o-ring, washer and screw.
