The desired measurement mode is easily selectable through a membrane keyboard on the front panel. Conductivity measurements are automatically compensated for temperature changes with a fixed coefficient of 2%\u002F°C. The HI 761285 probe features a built-in temperature sensor, and it has been designed to require little maintenance. The meter can be calibrated at one point for EC or TDS, while the temperature range is factory-calibrated.\u003C\u002Fp>\u003Ch2>TAKING MEASUREMENTS\u003C\u002Fh2>\u003Cul>\u003Cli>The meter is supplied complete with a 9V battery.

The display will then show the measurement automatically temperature compensated for temperature with the appropriate indication: “μS” symbol indicates the meter is in EC mode, while no symbol means that the meter is in TDS mode.\u003C\u002Fp>\u003Cfigure class=\"image\">\u003Cimg style=\"aspect-ratio:416\u002F83;\" src=\"https:\u002F\u002Fmanualsfact.com\u002Fmedia\u002Fposts\u002F660fec0389b73d8967d3ee38\u002Fhanna_instruments_ec,_tds,_and_temperature_meter_hi_8730-taking_measurements.png\" alt=\"hanna_instruments_ec,_tds,_and_temperature_meter_hi_8730-taking_measurements.png\" width=\"416\" height=\"83\" loading=\"lazy\">\u003C\u002Ffigure>\u003C\u002Fli>\u003Cli>• To read the temperature of the solution, select the temperature\u003Cbr>mode, by pressing the “°C” key.\u003C\u002Fli>\u003Cli>\u003Cp>Wait a couple of minutes for the reading to adjust and stabilize.
