22.3 Calibrating the light sensors and adjusting the controller display –
KBF LQC
The light sensors are supplied with a calibration certificate giving at least 2 measuring values with the
related measuring current values.
For recalibrating the light sensors, send the sensors to BINDER factory service.
If an independent reference measuring device is used to directly compare the light intensities,
it must bear the same spatial sensitivity characteristics (spherical) as the sensors of the
BINDER system (chap. 20.5.4).
22.4 Cleaning and decontamination
Clean the chamber after each use to avoid potential corrosion damage by ingredients of the test material.
DANGER
Electrical hazard.
Danger of death.
∅ Do NOT spill water or cleaning agents over the inner and outer surfaces.
Before cleaning, turn off the chamber at the main power switch and dis-
connect the power plug.
Completely dry the appliance before turning it on again.
22.4.1 Cleaning
Disconnect the chamber from the power supply before cleaning. Disconnect the power plug.
The interior of the chamber must be kept clean. Thoroughly remove any residues of test mate-
rial.
Wipe the surfaces with a moistened towel. In addition, you can use the following cleaning agents:
Exterior surfaces
inner chamber
racks
door gaskets
Standard commercial cleaning detergents free from acid or halides.
Alcohol-based solutions.
We recommend using the neutral cleaning agent Art. No. 1002-0016.
Instrument panel Standard commercial cleaning detergents free from acid or halides.
We recommend using the neutral cleaning agent Art. No. 1002-0016.
Light sensors
(KBF LQC)
Wipe with a soft, if desired moistened towel. Do not mechanically strain the light
sensors during cleaning and take care not to scratch them.
Zinc coated hinge
parts
rear chamber wall
Standard commercial cleaning detergents free from acid or halides.
Do NOT use a neutral cleaning agent on zinc coated surfaces.
Do not use cleaning agents that may cause a hazard due to reaction with components of the device or the
charging material. If there is doubt regarding the suitability of cleaning products, please contact BINDER
service.
