Instruction Manual CON 6/TDS 6

IMPORTANT NOTES:

1. Meter allows a tolerance range of ±40% of its

calibration standard. An error message “Err 1” will be

displayed for 3 seconds if you attempt to calibrate

with a solution whose value is outside the tolerance

range.

For instance: For 1413 µS conductivity calibration

standard, 40% tolerance is from 848 µS to 1978 µS.

2. If the temperature (t °C) of the conductivity calibration

solution is below 0 °C or above 50 °C (0°C < t °C >

50 °C), an error message “Err 2” will be displayed

when performing the auto calibration, and meter will

return to measurement mode.

3. All new calibration data will over-ride existing stored

calibration data for each measuring range calibrated.

4. It is important to use new conductivity calibration

standards.

5. Low conductivity standard solution (less than 20 µS

/cm) cannot be available easily. Such low conductivity

standard will be contaminated as soon as it is

exposed to the air therefore exercise caution during

calibration in the first measurement range (0.00 to

20.0 µS /cm).
