Temperature Calibration
With Temperature probe
The .temperature .probe .provided .with .the .meter .is .factory-calibrated . .Over .time, .
temperature .calibration .may .drift .and .require .calibration . .If .there .is .a .need .to .replace .
with .the .new .probe .you .should .calibrate .the .temperature .probe .prior .to .pH .calibration .
1 . . Connect .your .temperature .probe .to .the .meter . .Press . .to .enter .the .
temperature .mode .until .“°C” .annunciator .appears .in .the .LCD . .
2 . . Compare .the .displayed .value .to .a .NIST .certified .thermometer .or .other .
thermometer .known .to .be .accurate . .For .best .accuracy, .place .both .the .probe .and .
thermometer .in .a .constant .temperature .bath . .
3 . . Press . .to .enter .temperature .calibration .mode . .The .LCD .shows .“ CA ” .
momentarily .and .displayed .reading .flashes . .
4 . . Press . .until .the .LCD .display .shows .the .desired .temperature . .The .meter .
allows .an .adjustable .maximum .value .of .± .5 .˚C .from .factory .default .
5 . . To .cancel .or .abort .this .operation, .press . . .Note .no .new .value .will .be .stored .
into .the .meter‘s .non-volatile .memory . .To .confirm .calibration, .press . . .The .LCD .
