Performing a user

calibration

Proceed as follows if you want to perform a user calibration:

In the

Settings of sensors and diff. sensors

menu, set the

Signal

smoothing

setting to

Off

Subsequently, leave the menu with

Save and quit

How to navigate to the

Settings of sensors and diff. sensors

menu and

the operation of the menu is described in section 3.4.3.

At least one value pair and a maximum of two value pairs can be

entered for a valid calibration. The values must be in ascending order.

If they are not in ascending order, a calibration error will occur.

The entry of calibration values outside the measuring range leads to a

calibration error.

1. Bring the sensor into the measuring position.

2. Switch to the measured value display with <M>.

3. Wait for a measurement, read the raw value (without dimen-

sion) and note it down. In the case of fluctuating values,

observe several measuring cycles and average the individual

raw values.

4. Take a sample at the same time as the measurement and as

close to the UV-VIS sensor as possible.

5. Determine the reference value and note it down as a value pair

together with the raw value.

6. For a two-point calibration:

Determine the second value pair (step 4 to step 6).

7. Sort the values pairs in ascending order.

8. In the

Settings of sensors and diff. sensors

menu, enter the

value pair or pairs (see the following table).

1 2 ... 25 26 27 28 29 30 31 32 33 34 35 ... 65 66
