About Calibration

50% tolerance

To ensure higher accuracy, the tester must be calibrated on a regular basis.
Calibration can be manual or automatic (only for ECTestr11 & ECTestr11+); calibration
can be 1-point or multi-point. You can choose any combination of the above two
options for calibration. If you calibrate the tester for 1-point, the calibration is applied
for all the measuring ranges. In applications where you need higher accuracy, and
when you intend to measure values in more than one range, it is recommended to
select multi-point calibration.

Selection of Automatic or Manual Calibration

ECTestr11 & ECTestr11+ models support both automatic & manual calibration while
all other models have to be calibrated manually. In automatic calibration, the tester
automatically detects and verifies known conductivity standard solutions (84uS,
1413uS & 12.88mS) . In manual calibration, you can use non-standard solutions
which may be specific for your application.

The factory default is Automatic calibration (Auto). You can enable or disable
automatic calibration as described below (for only ECTestr11 & ECTestr11+ models).

Selection of 1-point or Multi-point Calibration

The factory default is 1-point Calibration. For higher accuracy, it is recommended that
you calibrate the tester for multiple ranges if you intend to measure values in multiple
ranges. You can enable or disable multi-point calibration as described below.

Note:Note:

Note:

If you have selected a specific measuring range for the tester, selecting multi-

Note:Note:
point calibration has no meaning, as the tester can only be calibrated for 1-point
for the selected range. Set the tester to ‘AUTO’ measuring range if you wish to
calibrate multi-points.

Auto Calibration

Auto calibration feature is available only for conductivity in ECTestr11 &
ECTestr11+ models. Make sure that ‘auto calibration’ is enabled as described in
the previous section. Auto calibration is suitable if you use standard conductivity
solutions for calibration process.

If you selected 1-point calibration, you need to choose a calibration standard
corresponds to the selected measuring range of the tester listed below. If you
have selected multi-point calibration & AUTO measuring range, you can choose any
of the calibration standards listed below. During auto calibration, the tester
recognizes the calibration standard if its value is within 50% tolerance. For multi­point calibration (with AUTO measuring range), the tester automatically scans
through all possible calibration points until all of them are calibrated.
