Measurement
5.1
Measuring procedure setup
Requirement:
The measuring instrument must have the same temperature as the prod-
uct to be measured as precisely as possible. It is recommended to let the measuring
device adjust to the temperature close to the product before measuring.
1. Turn on the device (see
"4.1 Turn on the device"
).
2. Select the desired product type (see
"6. Product types"
) by pressing the
or
button (see
"6.1 Selecting the product type"
).

5.2.1 Measurement on stapled pulp sheets / bows
Requirement:
The pulp height has to be at least 30 cm on
the top and bottom side of the electrodes to avoid incor-
rect measurements. The device has approximately the
same temperature as the measured material. The inser-
tion position is designed to ensure that the contact
pressure on the electrodes lies around 250kg/m²
(2.45kN/m²).
1. Take the measuring unit by the handle with
one hand and gently lift the pulp pile. Insert the
measuring electrodes into the crack of the pile (see
figure
9 and 10
).
2. The electrodes have to be inserted as far as possi-
ble into the pile ( at least ¾ of the electrode length)
(see figure
11
).
3. Make sure that the IR temperature sensor is
exposed and can measure the temperature of the
pulp surface. If the IR sensor does not face the pulp
surface, a too high temperature, due to hot parts
or the body surface as well as a too cold tempera-
ture, due to cold parts or clothing, can negatively
affect the measurement result caused by incorrect
temperature compensation (figure
12
).
