Calibration Tips
You .only .need .one .calibration .for .measurement .throughout .the .entire .range .of .the .
meter . .If .a .range .was .not .calibrated, .the .meter .automatically .detects .the .closest .range .
calibrated .and .uses .that .calibration .information . .However, .only .the .ranges .that .were .
calibrated .have .maximum .accuracy . .
If .you .are .measuring .in .ranges .near .to .or .greater .than .20 .mS .(10 .ppt), .or .near .to .or .
lower .than .100 .μS .(50 .ppm), .calibrate .the .meter .at .least .once .a .week .to .get .specified .
±1% .F .S . .accuracy . .
If .you .are .measuring .in .the .mid-ranges .and .you .washed .the .probe .in .deionized .water .
and .stored .it .dry, .calibrate .the .meter .at .least .once .a .month . .
Wet .the .probe .for .10 .minutes .before .calibrating .or .taking .readings .to .saturate .
the .probe .surface .and .minimize .drift . .If .you .make .measurements .at .extreme .
temperatures, .calibrate .the .meter .at .least .once .a .week . .
You .should .only .use .the .conductivity .probe .specified .for .these .meters . .These .probes .
have .a .built-in .temperature .sensor . .If .you .use .a .different .probe .without .a .temperature .
sensor, .you .must .measure .the .solution .temperature .separately .and .manually .enter .the .
solution .temperature . .See .the .
Manual Temperature Compensation section .
