Operating instructions for the calibration devices for tube sensors and blade sensors

These operating instructions enable safe and efficient use of the calibration devices for pipe sensors and blade sensors.

Calibration

Prerequisites: Calibration device (Art.No.10006) and humidity standards (Art.No.10005).

The device, the calibration device and the calibration solutions must have a temperature between 20.0 °C and 26.0 °C. It is recommended that the device, the calibration device and the calibration solutions are stored in a room with low temperature fluctuations for 24 hours before the calibration process.

Calibration ampoules for calibration

Relevant uses:
Only suitable for checking or calibrating moisture analyzers.

Certified calibration ampoules:
Use with article 10072, calibration device.
The calibration ampoules each have a different relative humidity, e.g. 50% or 35% etc. The higher the relative humidity of the material, the higher the humidity of the calibration ampoules.

Calibration procedure

Make sure that all appliances and solutions have reached the recommended temperature.
Store the devices and solutions 24 hours before calibration in a room with minimal temperature fluctuations.
Use the certified calibration ampoules to perform the calibration.
Note the results and adjust the meter according to the manufacturer's instructions.

Following these steps will ensure the accuracy and reliability of your moisture meters.

Important notes

The use of non-certified calibration ampoules can lead to inaccurate measurement results. It is therefore important to only use products recommended by the calibration device and the manufacturer. Always ensure that the calibration ampoules are stored and used in accordance with the manufacturer's instructions to ensure optimum calibration

Performance features

Mounting the calibration device for pipe sensors

Place the sealing ring over the thread of the lower part, as shown in Fig. 1.
Place the textile pad in the lower section
Hold the ampoule by the neck and gently tap to transfer all the liquid into the lower part of the ampoule.
Now carefully break off the head of the ampoule at the marked point.
Pour the solution completely onto the textile pad.
Carefully place the upper section on the lower section and screw the upper section on clockwise.
- Recommendation: Leave the lower part on the table while tightening the upper part.
- Note: If necessary, only lift the calibration device straight up. Do not tilt or turn it over.
Loosen the fastening nut counterclockwise until the sensor tube of the measuring device can be inserted without excessive pressure.
Now carefully push the sensor tube of the measuring device into the upper part as far as it will go
Secure the calibration device on the sensor tube by tightening the previously loosened fastening nut.
- Make sure that you only lift the device with the calibration device straight up and do not tilt or turn it over, as this could damage the sensor.
- Note: Leave the calibration device mounted on the sensor tube until specifically instructed otherwise.
- Tip: Place a spacer under the device so that the device and the calibration device rest horizontally on the table.

Your advantages

Mounting the calibration device for blade sensors

Insert the seal (30 mm) (1) into the housing
Slide the blade sensor into the housing.
- Note: The blue area of the blade sensor must be visible.
Place the textile pad in the lower section .
Hold the ampoule by the neck and gently tap to transfer all the liquid into the lower part of the ampoule.
Now carefully break off the head of the ampoule at the marked point.
Carefully pour the dampening standard onto the textile pad.
Place the narrow seal (34 mm) (4) on the lower part, followed by the washer (3) and then the wide seal (34 mm) (2) (Fig. 10).
Carefully place the housing together with the blade sensor on the lower part .
- Recommendation: Screw the lower section into the upper section while lying on the table.
- Take care: Lift the device with the calibration device straight up and do not tilt or turn it over, as the sensor could otherwise be damaged by the liquid.
Leave the calibration device mounted on the blade sensor until explicitly instructed otherwise.
Place a spacer under the device so that the device and the calibration device rest horizontally on the table.
