Positioning the instrument

Insert the sword-sensor into the stack for only approx. 10 cm, and push it a

few more centimetres into the stack every 10 seconds. Let your humimeter

RH5 adequately adjust to the material (at least five minutes) before you start

to measure, particularly when the material pile was stored at a different

temperature than the device. When removing the sword-shaped sensor

please ensure that there is no up or down movement, because this could

deform the sensor. For heavy stacks and rolls please use the optionally

available sword sensor holder and the tool for removing the sword sensor

holder.

Measurement

To switch on the instrument, press the key for

three seconds.

After showing the logo, the measuring window opens and

the current temperature and moisture value is displayed.

In the type selection menu the calibration curves can be

changed by pressing or . The calibration curves

saved in the device can be found in the following list.

Description of definitions

Relative air humidity: indicates the relation between the current water

vapour pressure and the maximal possible water vapour pressure (called

saturation vapour pressure)

The relative humidity shows the degree the air is saturated with water

vapour. For example:

50% relative humidity indicates that at the current temperature and the

current pressure the air is saturated with water vapour for half of its value,

100% relative humidity means that the air is totally saturated. When the air

has more than 100% of relative humidity, the excessive moisture would

condense or form fog.

Dew point temperature: The dew point indicates the temperature that the

not completely saturated air has to reach in order to be completely saturated

with water vapour. If the room with the current relative humidity is cooled

down to the dew point temperature, the water vapour begins to condense.

Application range

Within the normal application range (normal range) the accuracy of the

device is as indicated. A long-term application beyond the normal application

range (max. range), particularly at an air humidity of more than 80%, can

lead to higher measuring errors (+3% after 60 hours). Back in the normal

application range, the sensor will return to the indicated accuracy

automatically.

Proceedings

Preparation

To ensure as good as possible inspection results it is essential that the

measuring device, the calibration equipment and the calibration ampoules

have approximately the same temperature.

This temperature has to be between 20°C and 26°C.

The best way to ensure the same temperature of the different components is

to store all components together in a room with only small temperature

fluctuations minimum over night – better for 24 hours.

Components of calibration equipment

In this image you can see the components of the

calibration equipment and a calibration ampoule

with humidity standard.

Assembly of calibration equipment

1. Put in the first gasket ring in the upper part of the calibration device.

2. Push in the sword sensor in the upper part as shown in the picture.

3. Now put the second gasket ring into the upper part.

4. Lay in the textile pad in the bottom part of the calibration device, and

pour the humidity standard carefully at the textile pad.

5. Now put the third gasket ring into the bottom part.

6. Fit the metal ring on the third gasket.

7. Take the upper part with the RH5.1 and attach these carefully at the

bottom part of the

calibration device.

page 8 version 2.0_

8. Pick up the RH5 together with the calibration device STRAIGHT and

DON´T TURN IT AROUND. Screw it up like shown in the picture.

Then put the RH5 with the calibration device down on a table carefully and

proceed as follows.

Conditioning the sensor

To achieve best results, let the sensor adjust for two hours.

The temperature has to be between 20°C and 26°C.

If the shown measuring value differs more than the factory tolerance

(2.0% r.h.) , we recommend to carry out a recalibration as follows.

Offset adjustment

1. Leave the measuring device in the calibration equipment, and switch it

on.

2. Press the Rolling Menu button until you reach the main menu.

3. Select the menu item Options by pressing the button and confirm by

pressing .

4. Navigate to Setting using the button and confirm by pressing

again.

5. Enter the superuser password using the buttons resp. and confirm

by pressing .

•The superuser password after consignment is the serial number of

the device, shown on the display after switching on the device or in

menu item Status.

6. A query if a setting is desired appears. Confirm by

pressing .

7. Wait until the bar has risen completely. The

device adjusts by itself and automatically jumps

back to the measuring window. The adjustment is

completed now.

Check the result before you remove the device

from the calibration equipment. Depending on the

temperature the display should show a humidity

around 50% now.

If you made a mistake during the setting, you can reset to the factory

calibration as follows:

Reset to factory calibration

1. Press the button 2 times to reach the menu point Options.

2. Select the menu item Reset using the button and confirm by pressing

3. Enter the superuser password using the buttons resp. and

confirm by pressing .

•The query reset? appears on the display.

4. Press the button for resetting the device to the factory calibration.

•The software reloads the factory calibration data and reboots the

device. This will need about 15 to 20 seconds.

5. Pressing the button you can exit without any changes.

Conditioning of the sensor

The conditioning of the sensor (time until the device shows the actual

measuring value) depends on several parameters. The parameter

responsible for the highest measuring error is a temperature discrepancy

between the sensors resp. the whole measuring instrument and the material

to measure resp. the air.

In order to fasten the conditioning, the following proceedings are possible:

Spaced insertion of the sword sensor

oInsert the sword-sensor into the stack for only approx. 10 cm, and push it

a few more centimetres into the stack every 10 seconds.

In case of a high temperature difference repeat this action – if necessary

several times!

oIf you use the sword sensor holder, please ensure that both the sword

sensor and the sword sensor holder are adjusted to the surrounding

temperature of the material.

In this case insert the sword sensor holder at frequent intervals and leave

the sword sensor in the sword sensor holder for an appropriate period.

Care instructions

Do not drop the instrument or expose it to excessive temperatures. The

instrument is not waterproof. Do not immerse the sensor in liquid.

The intervals for checking the instrument depend on your operational

demands and the required level of accuracy. In general the drift of the sensor

page 10 version 2.0_

according to the degree of use (constant humidity or use within the whole

moisture measuring range) is beneath 0.5 % per year. You can check

humimeter RH5.1 instruments by yourself using the calibration equipment

(see optional accessories). For a fee, Messtechnik Schaller GmbH can also

carry out a calibration at their factory. On demand you will also receive a

calibration certificate.

Changing the batteries

Press with your finger onto the arrow of the battery cap und pull it back.

Remove the empty batteries. Put four new 1.5 Volt AA Alkaline batteries in

the device. Make sure that the position of the battery poles is correct. Press

down the batteries and close the cap.

Exemption from liability

For miss-readings and wrong measurements and of this resulting damage

we refuse any liability. This is a device for quick determination of moisture.

The moisture depends on multiple conditions and multiple materials.

Therefore we recommend a plausibility check of the measuring results. Each

device includes a serial number and the guarantee stamp. If those are

broken, no claims for guarantee can be made

If the battery symbol appears in the measuring window

resp. if a critical charge of battery is shown in the status,

the batteries have to be changed IMMEDIATELY.

If you do not use your humimeter device for a longer

period, remove the batteries. For eventual resulting

damages we cannot provide any warranty.

In case of a faulty device, please contact Schaller

GmbH (www.humimeter.com) or your dealer.
