1. 800 661 2023 35 Todd Road Georgetown Ontario Canada L7G 4R8 Clean the probe tip Follow the Cleaning and Maintenance instructions The water could be pure and non conductive or product may be coating the probe in which case shake the probe for a while in the water column to clean product from the probe The probe circuitry could be damaged due to high voltage static in the well Always use a ground cable Please contact Solinst Solinst Web Site www solinst com E mail instruments solinst com2. Solinst Operating Principle The Solinst Model 122 Mini Interface Meter has a narrow 5 8 16 mm diameter probe An infra red circuit detects the presence of a liquid and a conductivity circuit differentiates between conductive liquid water and non conductive liquid LNAPL or DNAPL product Equipment Check Check the electronics and battery condition by turning the unit ON A brief tone and red light indicate that the meter is functional IMPORTANT For safety always ground the meter by attaching the ground cable to the metal well casing or to a suitable grounding rod Failure to properly ground this instrument could cause damage to probe electronics or result in an explosion from any flamable gases trapped in well Remember to switch off after use as the meter will not turn off automatically Field Measurements Mini Interface Meter Operating Instructions Model 122M Cleaning and Maintenance After each use the tape should be wiped clean and carefully rewound onto the reel An alternative is to steam clean the tape only The probe should be cleaned as follows 1 Wash the probe thoroughly with a non abrasive mild detergent DO NOT USE ANY SOLVENTS Use a soft cloth around the pins and on the prism on the end of the probe to remove all product Use lukewarm water not hot water or you may damage the probe 2 Rinse probe thoroughly with distilled water wipe dry 3 Return the probe to the hol
3. der Battery Replacement If the tones get weak battery power is getting low and you should replace the battery before you go into the field Push battery drawer in and up and then pull out The battery drawer should eject slightly to make pulling out easier Replace the battery with an alkaline 9 volt battery IMPORTANT Reverse polarity can cause probe damage Ensure correct 1 Turn the rotary power switch ON A brief tone and light indicate that the meter is functional The meter will stay banen placement ON until the power switch is turned back to OFF 2 Lower probe into well If a tape guide is used lay the tape General Tips onto the groove on the top Measurements will be read at 1 The probe should be cleaned after each use the point of the V notch on the tape guide Remember to deduct 2 10 ft or 60 mm 2 Always use the grounding cable 3 A steady tone and light indicate a non conductive liquid 3 Do not drop probe e g product An intermittent tone and light indicate a 4 If the tones are weak replace battery conductive liquid e g water 5 Before storage make sure that the meter is turned OFF 4 For floating aes Pe aa a product interface 6 The meter can be checked by placing the probe in pure aia aa di al alae ara phase product for example lamp oil avoid bright 5 The interface between the LNAPL and water should be sunlight during testing A steady tone and light sho
