Maintenance
The Blanko is designed to reduce the manual maintenance to a minimum. All metal parts
are stainless steel (SS 2343/SS316). The enclosure is IP68/NEMA 7. The sensor cable is
a specially manufactured PUR™ with a strong shield and extra heavy wires to withstand
mechanical wear for a long life. The sensor and enclosure cable fittings are high quality
MatchClamp™ to ensure a water proof connection even should the outer shield be
damaged.
Inspection of the sensor
The sensor head should be cleaned if any solids or fouling of the measuring windows
occurs. In order to verify the necessity of cleaning, place the sensor in clean, de-aerated
water and read the display value. The value should not differ more than ±100mg/l from
zero. If the value is off the cleaning is required, a new zero calibration may be
performed. See section Calibration .
In order to verify if a depth calibration is needed, lower the sensor into water until the
one meter cable mark. The depth value should not differ more than ±2cm (±1”). A higher
deviation requires a zero and one meter calibration, see section Calibration .
When cleaning the sensor, it is preferred to use the Cerlic Sensor Cleaning (CSC) liquid.
It is also possible to use a soft cloth and water. Pay attention not to scratch the
measuring windows or damage the built in pressure sensor.
Trouble shooting
If the Blanko values for depth and concentration should deviate, a new calibration for
depth and/or concentration. Please see section Calibration for instructions.
In case of any malfunction that is not possible to correct with a new calibration, please
contact Cerlic or a local Cerlic representative. In case of sending the Blanko to Cerlic for
check up or repair, please make sure to use the form for Return of Material (RMA) prior
to dispatch. The RMA document can be downloaded from the Cerlic web page
www.cerlic.com . The WEB page also has the actual and correct receiving address.
