1. Maintenance The device is maintenance free if used for its intended purpose Battery Charger LOW BATT appears at the LCD panel when the battery is weak The integrated rechargeable NiMH battery can be quickly and reliably recharged with the included ACS 410 mobile battery charger Charging time for a fully depleted battery is about 2 2 hours The charger can be connected either to a 230 V mains outlet or to a 12 V automotive cigarette lighter with the help of the included DC connector cable Charging Procedure O Remove the dust cap from the charging socket at the MUDLine TGS O Plug the connector cable into the charger and screw into place O Plug the charger into a 230 V mains outlet or an automotive cigarette lighter via the DC connector cable O The red LED on the charger blinks for about 10 seconds battery contact detection test O The LED then remains continuously lit Battery is being charged O The green LED lights up and the red LED goes out The battery is fully charged and the charger has switched to the trickle charge mode O If the battery is defective the red LED continues to blink after the test phase O The yellow knob can be used to fully deplete the batteries but this is not necessary with the utilised NIMH batteries Attention After charging plug the dust cap back into the charging socket on the MUDLine TGS Charger Functions O Charging is monitored by a micro controller O T2. Procedure O Switch the instrument on 002 005 is displayed offset Increased Sensitivity For minimal turbidity difference i e no clear cut boundary between sludge and clear phase e g churned up sludge The instrument is calibrated and the desired switching threshold is selected as follows Remove a specimen with the desired concentration of sludge and pour it into a bucket Set a bucket full of clear water next to the sludge bucket Immerse the measuring probe into the sludge specimen to a depth o at least 10 cm Adjust the potentiometer as described above Repeat several times if necessary Greatly Increased Sensitivity O In case of extremely minimal sludge concentration gt Select measuring range 2 Minimal turbidity differences are then detected O Proceed as described above Attention O The instrument reacts very sensitively to differences between purified and turbid water in this operating mode and detects even extremely small suspended particles SU0306a doc 05 06 IER GmbH Cleaning o Clean the drum with integrated electronics with a moist cloth only Do not immerse in or spray with water o The measuring probe and the cable can be cleaned under running water with a soft brush Do not use high pressure water blasters or steam cleaners gt The submersible pressure transducer will otherwise be damaged o Use mild household cleaners only Do not use solvents or degreasing agents
3. el Measuring Instrument Safety Precautions e Do not open the housing e The device may only be connected to the included battery charger which is described in the operating instructions e Clean the cable drum with integrated electronics with a moist cloth only Do not immerse in or spray with water Functions Description The portable MUDLine TGS is used for the measurement of sludge levels in settling and precipitation tanks as well as in small effluent treatment plants It detects the transition zone between the clear phase and the precipitated sludge after which the momentary immersion depth of the measuring probe can be read from the integrated digital display The instrument is equipped with an integrated automatic measured value memory for immersion depth The instrument can be set to the desired switching threshold with the help of the sludge concentration adjusting knob and the measuring range selector switch The instrument is functional to an immersion depth of up to 10 metres IER MeB und Regeltechnik GmbH Innstrasse 2 D 68199 Mannheim Germany Phone 49 0 621 84224 0 Fax 49 0 621 84224 90 e mail info IER de e Internet www lIER de SU0306a doc 01 06 IER GmbH wis Technical Data Setting range switching threshold Measuring range 1 standard measuring range Measuring range 2 increased sensitivity Immersion depth measuring accuracy Approx 1 cm Ambient tem
