Calibration Mode (CAL)
Selecting a calibration standard
For best results, select a conductivity or TDS standard
near the sample value you are measuring. Alternatively,
use a calibration solution value which is approximate 2/3
of the full scale of the measurement range you plan to
use. For example, in the 0 to 1999 uS range, use 1413 uS
solution for calibration.
DO NOT reuse the calibration solution. Contaminants in
the solution will affect the calibration and the accuracy
When to do the calibration?
Calibration is necessary and should be done regularly.
If measure the mid-ranges, calibrate the meter at least
once a month. Soak the probe for 15 mins before
calibration or measurement can saturate the probe
surface and minimize drift.
If measure the extreme temperatures or special
concentration (<100uS or >2mS), calibrate the meter at
least once a week to get specified accuracy
Conductivity calibration
1. Dip the probe into demineralized or distilled
water for about 30 minutes to rinse the probe.
2. Select the conductivity standard for calibration.
3. Pour enough solution into two separate clean
containers.
4. Power on the meter. Select the mode as
conductivity measurement mode.
5. Rinse the probe into one of above containers.
Gently stir the probe.
