▬
After turning on, the temperature is checked making sure that
the device is within the allowable operating temperature
range (15-30 °C) and is ready for measurement. The current
device temperature and a corresponding message is shown
on the display.
▬
When an allowable operating temperature is reached, the
following message is shown on the display,
“Detection of
ambient temperature”
. The measuring head is still not
allowed to be submerged in the dampening solution. By
confirming the request, the actual ambient temperature is
saved and the device is ready for measurement. The main
menu is shown in the display with the following items:
•

Service
▬
By using the selection buttons, navigate to
“Measure”
and
press the enter button „>>>“. The actual measurement does
not yet begin, however.
▬
Fill the measuring dish with 25 ml of dampening solution
immediately before the measurement. Use the delivered tool
for taking a precise sample in order to avoid overfilling, which
could cause the measuring dish to overflow when the meas-
uring head has been placed. An accurate amount also avoids
an unnecessarily long warm-up time.
▬
Now place the measuring head inside the measuring dish. The
frame of the measuring head should rest evenly on the
heating plate. This is assured due to the construction of the
measuring device when placed on an even surface. Do not
place any additional underlays underneath the measuring
dish or the hand-held device!
▬
Begin the measurement by pressing the enter button „>>>“.
▬
The dampening solution will then be warmed-up to a tem-
perature between 20 °C and 25 °C. The message
“Heating
phase“
as well as the actual and target temperature is shown
on the display. Attention: The measuring dish heating plate
will become hot during the heating phase! Do not touch the
heating plate! Do not start a measurement without dampen-
ing solution in the measuring dish!
