Bosch Professional GIS 1000 C Original Instructions Manual page 13

– Marking (p) in the red range: There is an increased risk of
mould because the humidity is too high or the surface
temperature is close to the dew point temperature. The
respective value flashes in the indicator.
A mould risk warning is given when the surface temperature
is 80 % of the dew point temperature.
Note: Mould spores cannot be detected with the measuring
tool. It only indicates that mould may form if the conditions
remain unchanged.
Contact Temperature Mode
Contact temperature measurement enables the temperature
of an object to be measured directly using a commercially
available type K thermocouple.
The contact temperature measurement can be a helpful ad-
dition to the contactless temperature measurement. Applic-
ation is sensible particularly in situations in which the in-
frared measurement has principal disadvantages, e.g. in
temperature measurement in media, liquids, air currents or
surfaces with a low emissivity (polished metals).
There are specially optimised sensor geometries for various
applications in liquids, in air currents or on surfaces, which
allow correct measurement when using a suitable sensor.
Read and observe information from the thermocouple manu-
facturer if available.
Using a thermocouple principally requires direct contact
with the object measured. Pay attention here to potentially
arising hazards and the safety instructions.
In this mode, only the temperature of the temperature
sensor is measured. Other parameters are excluded here.
Note: Use type K thermocouples only. Measurements may
yield incorrect results if other types of thermocouples are
connected.
Open the flap (1) and connect the thermocouple at the
connection (25).
As soon as a thermocouple is connected, the (n) indicator
appears in the display. The measured value of the indicator
is continually updated. For the measurement, the measure
key (4) must not be pressed in this mode and the lasers are
deactivated. To achieve a reliable result, wait for the meas-
ured value to stop changing. This can take several minutes
depending on the version of thermocouple.
The contact temperature can, however, also be measured in
every mode in addition to the surface temperature. Then the
measured value is displayed in another place (s). The sur-
face temperature (n) is, however, always used to determine
thermal bridges and the risk of mould.
When the thermocouple is removed, the function
indicator (s) on the display goes out. Close the flap (1) again
after removing the thermocouple.
User mode
Surface temperature, ambient temperature and relative hu-
midity are measured in user mode. The dew point temperat-
ure and the average temperature (average of the surface
temperatures during the measuring period) are calculated
from these.
Bosch Power Tools
You can hide the following values in the display as required:
Average temperature, relative humidity, ambient temperat-
ure and dew point temperature.
To do so, open the <Main Menu> (see "Navigating in the
<Main Menu>", page 14). Select the <User Mode> sub-
menu. You can switch the indicators for <Average Temp.>,
<Humidity>, <Room Temperature> and <Dew Point> on
and off here.
For surface temperature measurements, you can choose
whether the minimum and maximum values (j) of the result
scale (k) are adapted automatically or defined manually. Go
to the <User Mode> menu and then the <Scale Range>
submenu.
– If you want the values (j) to be determined automatically
as in surface temperature mode, select <Auto>. Once the
difference between the measurements taken is more than
3 °C, the minimum and maximum temperatures measured
during the process will appear on the display (j).
– If you want to define the values manually, select
<Preset>. Set the values you require in the <User
Mode> menu under <Scale Lower Limit> and <Scale
Upper Limit>. The minimum and maximum values you
have set manually will appear on the display (j). This en-
ables screenshots of different measurements to be com-
pared using the marking (p), for example.
Surface temperature alarm
The surface temperature alarm can be used in all modes ex-
cept contact temperature measurement. You can set a min-
imum and a maximum temperature.
If the temperature is below the minimum temperature, the
temperature alarm indicator (m) flashes blue and (if this fea-
ture is switched on) a warning signal sounds.
If the temperature is above the maximum temperature, the
temperature alarm indicator (m) flashes red and (if this fea-
ture is switched on) a warning signal sounds.
To use the surface temperature alarm, open the <Main
Menu> (see "Navigating in the <Main Menu>", page 14).
– Select the <Alarm> submenu.
– Set <Alarm min/max> to <On>.
– Set the minimum temperature under <Alarm min>.
– Set the maximum temperature under <Alarm max>.
The minimum and maximum temperatures will remain saved
if you set the alarm to <Off>.
Data transfer
Saving/displaying/sending the results of a measurement
After measuring an object, the memory symbol appears on
the display to indicate that you can save the results. Press
the save/send button (9) to do this.
The results of the measurement are saved as a JPG file
(screenshot of the fixed display).
– To display saved screenshots, press the
left-hand function button (17) under the gal-
lery symbol (q). The most recently saved
photo appears on the display.
