Measuring procedure RM1 recycling-material probe

1. For a correct measurement please ensure that the device has
the same temperature than the recycling material (+/-3°C). For
that reason, let your humimeter RM1 adjust to the surrounding
temperature of the material for at least half an hour before
measuring.

2. Switch on the device: Press the

key for

three seconds.

3. Plug the probe of your RM1 recycling­material probe straight into the
recycling material. It is not allowed to
load the measuring head incorrect or drop
it down!

4. Plug in the sensor cable into the socket of
the RM1. Take care of the correct
position and fix it with the knurled nut.

5. Change the calibration curve: Press one
time the key and then the or key.
The name of the calibration curve can be
seen at the head of the display.

6. Now the display shows the water
content. Left hand the temperature is
displayed.

7. To save the results in the save menu
press the ( button). The storage was
successful when the number in front of
the symbol increased. To reach the
store menu please press ( ) until the
appears.

8. To name the saved results press the
button.

9. Remove the RM1 probe

straight with

caution and clean the measuring head.

Recycling spez 1 and Recycling spez 2 include the possibility of a
thin water film on the plastic pieces, if the plastic content is really
high. Recycling spez 3 and Recycling spez 4 include the moisture
expansion by a high content of cellulose.

Compression of recycling material

The humimeter RM1 is calibrated for normally compressed
recycling material. If the measured recycling material is
compressed to a much lesser or greater extent, this will cause
measuring imprecision.

Selection of calibration curve

Due to the different compositions of recycling material there is no
standardised allocation of calibration curves. The different
calibration curves refer to the different contents of plastic and
cellulose in the material.

To ensure the best accuracy of your measurement you have to
carry out a comparison measurement using your online moisture
measuring system or by kiln-drying (according to DIN 287) once.

1.) Measure the water content of your recycling material using all
calibration curves that offer realistic results and write down the
measuring results of the different calibration curves.

2.) Now please note the effective water content determined by
your online measurement system or carry out a reference
measurement according to EN ISO 287.

3.) Compare the determined reference water content with the
measuring results of the different calibration curves. Use the
calibration curve with the measuring result nearest to the
reference water content.

Determination of the reference water content

The humimeter RM1 determines the water content, which means that it
calculates the moisture referred to the total mass (EN ISO 287):

Mn: Mass of the sample before drying
Mt: Mass of the dried sample

%WG: Calculated water content

housing. For that, hold the rubber
housing at the upper side and pull it
over. If your RM1 is provided with an
optional USB port, you have to remove
the protection cap before.

2.) Press with your finger onto the arrow of

the battery cap und pull it back.

3.) Remove the empty batteries.

4.) Put four new batteries in the device.

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

5.) Press down the batteries and close the

cap.

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.

Device maintenance instructions

To provide a long life of your device please does not expose it to
strong mechanical loads or heat e.g. dropping it or direct sunlight
exposure. Clean your device using a dry cloth. Any kind of wet
cleaning damages the device.

It is not allowed to load the measuring head incorrect (stress,
bending), otherwise it can be broken.

Plug and remove the

insertion probe of your RM1 straight into the recycling material.

The instrument is not rainproof. Keep it in dry areas. When the
device isn’t used for a longer period (2 months) or when the
batteries are empty, they should be removed to prevent a leakage
of the battery acid.

Transfer saved data to the PC

(Only possible with humimeter USB
interface module)

To send your saved logs to the PC, connect
the humimeter device to your PC using the
USB cable that was delivered with your
device. Carefully loose the protection cap on
your humimeter and plug in the USB mini B
connector. The bigger connector has to be
connected to a USB slot on your PC.
Start the LogMemorizer software on your
PC and switch on your humimeter RM1.

The data transfer can be started on your
humimeter or on the software.

Starting the data transfer on the humimeter:

Press the key until you reach the menu
(see image on the right). Then choose
„Send Logs“ and confirm by pressing the
key. Now choose „Manual Logs“ and
confirm with again. All saved logs will be
sent to your PC.

Starting the data transfer on your PC:

Press the button „remote control“ in the
LogMemorizer software. A drop-down menu
with several options opens (see image
below).

For transferring the data you can select
„Import last manual log“ (the last saved
measuring series is transferred) or „Import
all manual logs“ (all saved logs are
transferred).

If you click on one of these menu items, the
transfer starts immediately.

For the basic adjustments of the software
please look through the instructions on the
LogMemorizer CD.

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. In case of a faulty device,
please contact Schaller GmbH (

Most common reasons for miss readings with RM1
recycling-material probe

• Product temperature out of application range
Material below 0°C resp. above +40°C (32 to 104 °F) may
cause faulty measurements.

• Temperature difference between meter and sample
Please ensure that the device and the material under test are
being stored at the same temperature (+/-3°C) before
measuring. A high temperature difference has a negative
effect on the stability of the measurement results.

• Wrong calibration curve
Before you measure your sample, double check the correct
selection of the calibration curve.

• Frozen or mouldy material
If you measure such products, the accuracy will decrease.

• Water film at the measuring head
After measuring wet material a water film can arise on the
sensor head. This could lead to a too high result in the
following measurement. After measuring wet material clean
both black plastic parts accurately with a dry cloth.

It is not allowed to load the measuring
head incorrect (stress, bending), otherwise

it can be broken.

Plug and remove the

insertion probe of your RM1 recycling­material probe straight into the recycling
material.

Do not move the RM1 probe crosswise to the insertion direction
after plugging in.

Do not drop the measuring head or use it for
any ulterior purposes.

A broken measuring head is no case
of warranty!
