    General introduction thank you for selecting the 3020m meter. The 3020m is a precision tool that measure conductivity, salinity, tds and temperature. A built-in microprocessor stores, calculates and compensates for all parameters related to conductivity and temperature determinations. This unit has ...

    2. Allow temperature reading to stabilize, press "cal" key to enter the calibration mode. The "cal" icon appears on the lcd. Press "mode" key to sequentially view previous calibration settings. Tds tds is determined by multiplying conductivity (ms) by a tds factor. The default factor value is 0.65. ...

    Changes made will be cancelled and the previous calibration settings will be retained. Conductivity calibration (a) immerse the probe in a standard of known conductivity, preferably a standard in the middle range of the solutions to be measured. Immerse the probe (at least 2" to 3" or 5~7cm from the...
