measurement data

opened with MS

Excel

The csv file with the measurement data includes the following information:

z

Sensor name

z

Series number of the logger (SerNo)

z

Start and stop (time) of the exported data

z

Date and time of the measured values

z

Measured value

z

Measured value status (Valid; Invalid; OFL/UFL = outside the measuring
range; Ranging = optimal measuring range is being searched)

z

Temperature

z

Measured value status (Valid; Invalid; OFL/UFL = outside the measuring
range)

z

Measured value ID (MeasID)

z

Calibration ID (CalProtID) so you can allocate the calibration data if there
are several calibration procedures for the exported data - see csv file with
calibration data).

z

Date and time of the calibration (CalDateTime)

z

Settings ID (SetID) so you can allocate the settings for the exported data
- see csv file with setting data).

AutoRange

function

Due to the large scope of conductivity measurements ( 1 ... 1.000.000

μS/cm)

the WQL-Cond logger automatically searches for the suitable measuring
range. In the most unfavorable case (changing from the largest to the
smallest measuring range or vice versa) it takes the logger a response time
of approx. 8 seconds to do this.

In the case of extreme conductivity jumps, the logger can determine the real
conductivity value only approximately because of this response time.
Approximate values are indicated with the measured value status,
RANGING.

When measuring directly, the conductivity value is only displayed after the
suitable measuring range has been found.
