Operation

7.1 Calibrating DULCO

turb C

The DULCO

turb C is tested and

calibrated before leaving the factory.

For this reason, the DULCO

turb C

may be used immediately. Under

normal conditions, it is recommended

to carry out calibration at least once

every three months.
If the DULCO

turb C is in [CAL] or

[CONFIG] mode, the alarm relay

changes to alarm status. If no input is

made in [CAL]mode within a period of

15 minutes, the DULCO

turb C auto‐

matically switches back to [AUTO]

mode.

7.1.1 Standard solutions for cali‐

bration

If the DULCO

turb C is operated

over its complete measuring range of

0.02 NTU ... 1000 NTU, you must per‐

form calibration with all 3 standard

solutions (0.02 NTU, 10.0 NTU and

1000 NTU). If the sensor is only oper‐

ated in measurement ranges under

10 NTU, then you may perform a sim‐

plified calibration with standard solu‐

tions 0.02 NTU and 10.0 NTU.

CAUTION!

Use of diluted formazine
Possible consequences: Inaccurate

calibration. Malfunctions in dependent

processes.
Diluted formazine is instable. Ensure

that freshly prepared formazine solu‐

tion is used when performing calibra‐

tion.
If possible, use a standard solution

from Prominent for calibration. These

standard solutions are more stable

than formazine and have a minimum

shelf-life of 12 months. In doing so,

observe the use-by-date on the

standard solution packaging.
