Preparing the Meter for Calibration
Before .starting .a .calibration, .make .sure .you .are .in .the .correct .measurement .mode .
For .best .results, .select .a .standard .value .close .to .the .sample .value .you .are .measuring . .
Alternatively .use .a .calibration .solution .value .that .is .approximately .2/3 .the .full-scale .
value .of .the .measurement .range .you .plan .to .use . .For .example, .in .the .0 .to .2000 .μS .
conductivity .range, .use .a .1413 .μS .solution .for .calibration . .
Calibrate .to .all .measurement .ranges .to .ensure .the .highest .accuracy .throughout .all .
measurement .range . .Note .that .RL060C .will .not .accept .calibration .values .that .are . .
less .than .40 .μS/cm . .All .new .calibration .values .will .automatically .override .existing .data .
If .you .are .measuring .in .solutions .with .conductivity .lower .than .100 .μS/cm, .calibrate .
the .meter .at .least .once .a .week .to .get .good .accuracy . .If .you .are .measuring .in .the .mid .
ranges .and .you .wash .the .probe .in .deionized .water .and .store .it .dry, .calibrate .the .meter .
once .a .month . .If .you .take .measurements .at .extreme .temperatures, .calibrate .at .least .
once .a .week . .
Ensure .that .you .use .new .conductivity .standard .solutions .or .sachets .during .calibration . .
Do .not .reuse .standard .solutions .as .it .may .be .contaminated .and .affect .the .calibration .
and .accuracy .of .measurements . .Use .fresh .calibration .solution .each .time .you .calibrate .
your .meter . .Store .solutions .in .a .dry .and .cool .environment . . .
Always .rinse .the .probe .with .either .deionized .water .or .rinse .solution .before .and .after .
each .calibration/sample .measurement .to .avoid .cross-contamination . .For .details, .refer .
to .the .
Probe Care and Maintenance
section .
Note:
These meters are factory set to a temperature coefficient of 2.1%/°C. For
most applications this will provide good results. To set the temperature coefficient to
different value, see the
Temperature Coefficient
section. Also, see
Addendum 2
- Calculating Temperature Coefficient
to determine the appropriate temperature
coefficient for your solution.
Note:
The factory default value for normalization temperature is 25 °C. If you need
to normalize to a value other than 25 °C, see the
Normalization Temperature
section.
