Instruction Manual Mi 170 Bench Meter Note Note Note Note Note: The compensation is referenced at the selected reference temperature (see SETUP for details, page 26). Automatic (ATC): The EC probe has a built-in temperature sensor; the temperature value is used to automatically compensate the EC/TDS reading (from -20.0 –...
www.milwaukeeinst.com Notes Notes Notes Notes Notes: •If the reading is out of range, the full-scale value (100.0 for MTC/ATC mode or 400.0 for uncompensated TDS) will be displayed blinking. •If the SHIFT&RANGE/FIXED keys are pressed to freeze the LCD range and the reading goes out of range, the full-scale value of the frozen range will be displayed blinking.
Instruction Manual Mi 170 Bench Meter EC/TDS CALIBRATION EC calibration is a one-point procedure. Selectable calibration points are 0.00 μS for offset and 84.0 μS, 1413 μS, 5.00 mS, 12.88 mS, 80.0 mS, 111.8 mS for slope. Rinse the probe with calibration solution or deionized water. Immerse the probe into the solution.
www.milwaukeeinst.com Press the GLP/ACCEPT key to confirm calibration. The instrument stores the calibration value and returns to measurement mode. Notes Notes Notes: Notes Notes •If the uncalibrated reading is too far from the expected value, the “WRONG” and “SOLUTION” tags will blink. Calibration can not be confirmed. In this case check if the correct calibration solution has been used.

Instruction Manual Mi 170 Bench Meter reading is stable. When the reading is stable, the “READY” and “ACCEPT” tags will blink on the LCD. Press the GLP/ACCEPT key to confirm calibration. The instrument stores the calibration value and returns to measurement mode.
www.milwaukeeinst.com GOOD LABORATORY PRACTICE (GLP) GLP is a set of functions that allows storage and retrieval of data regarding the maintenance and status of the electrode. All data regarding EC and NaCl calibration is stored for the user to review when necessary.

TEMPERATURE CALIBRATION (for technical personnel only) The Mi 170 Mi 170 Mi 170 is factory calibrated for temperature. Mi 170 Mi 170 Martini’s temperature probes are interchangeable and no temperature calibration is needed when they are replaced. If the temperature measurements are inaccurate, temperature recalibration should be per- formed.
Instruction Manual Mi 170 Bench Meter EC SOLUTIONS TEMPERATURE DEPENDENCE The conductivity of an aqueous solution is a measure of its ability to carry an electrical current by means of ionic motion. The conductivity invariably increases with increasing temperature. It is affected by the type and number of ions in the solutions and by the viscosity of the solution itself.
