1 General
The HUMLOG 10 product family is a newdevelopment fromthe E+E ELEKTRONIK,
which standsout fromthe field due to itsexcellent price / performance ratio.
The compact design with itsmodulartechnologyfacilitatesa multiplicityof
applications.
The measurement valuescan be read very well on the large displayfroma distance
of severalmetres.
HUMLOG 10 family:
HUMLOG 10 =humidity/temperature internal
HUMLOG 10 TSE =humidity/temperature external, with 2-channels to which either2
temp. probesor1-2 combined humidity/temp. probe can be connected
HUMLOG 10 THC =humidity/temperature internal(without display)
Due to itsextremelylowenergyconsumption and large memory, the product is
excellentlysuited to long termmeasurement in both mobile and stationery
applications.
The SmartGraph 2 software, which is included with the product, offersthe useran
overviewpresentation and simple data archiving.
With the professionalversion of SmartGraph 2, the valuesfortemperature and dew -
point can be shown on the displayoptionallyin °C or°F, and the humidityin %
(relative humidity) orin g/m³(absolute humidity).
The technicaldata of the HUMLOG 10 can be found on the internet :

Explanations concerning the Displayoperation:
When a pre-set limit hasbeen exceeded the alarmsymbolof the corresponding
channelflashes. Once an alarmhasbeen recognised, the alarmsymbolremains
visible on screen in static formeven if the limit is no longerexceeded. The alarm
message can onlybe eliminated byselecting “Memory Readout”on the PC.
If the Pre-Selection mode (start flag)wasselected, the start-date and start-time for
data recording are shown on the Date/Time display. Once the pre-set date/time has
been reached the start flag is eliminated, the realtime clock displaybecomesactive
and data recording begins.
The unitsm/s(Channel1)and ppm/ hPa (Channel2)are reserved forotheroptions.
The specialfunctionsare reserved forotheroptions.

3 HUMLOG10 with Internal Sensors
The sensorsfortemperature and relative humidity, the corresponding sensor
adapters, and the serialinterface (RS232)are located on this module.
Illustration: Module with InternalSensors
Necessary calibration intervals are dependent on the environmentalconditionsand
the requirementsof the permissible tolerance deviations.
Asingle point calibration of the internalsensorscan be carried out using a
comparison standard. The captured offset valuescan be entered in the SmartGraph
software under: Measuring Instrument / Manage Measuring Instrument / Sensor
Electronics.
Two point calibrationscan onlybe carried out in the factory.

4 HUMLOG10 TSE forExternal Sensors
The connectorsforthe externalsensors, the corresponding sensoradaptersand the
serialinterface (RS232)are located on this module.
Illustration: Module forExternalSensors
Eitherone ortwo temperature sensorsorone to two combined
temperature/humiditysensorscan be connected here. (Two sensorsare only
available in connection with the Professionalversion of SmartGraph 2.
If onlyone externalsensoris used this is connected to the left hand sensorsocket.
In orderthat the instrument maycorrectlyrecognise the association of the sensors
to the channels, both sensorsocket positionsmust first be unoccupied. If a sensor
is connected to one of the two sockets, the indication UPLG (Unplug)appearsin the
corresponding line (Line 1=left hand socket, Line 2=right hand socket).

Manual HUMLOG 10
Page 8 of 17
If both socket positionsare free, the indication SENS appearsin the upperline, and
the first sensorcan be connected to the left hand socket position.
There are now10 secondsavailable (Countdown on the display) to connect an
optionalsecond sensorto the right hand socket position.
Necessary calibration intervals are dependent on the environmentalconditionsand
the requirementsof the permissible tolerance deviations.
Asingle point calibration of the externalsensorscan be carried out using a
comparison standard. The captured Offset values can be entered in the SmartGraph
software under: Measuring Instrument / Manage Measuring Instrument / Sensor
Electronics.
Two point calibrationscan onlybe carried out in the factory.
Instructionsforusing additionalextensionsforthe probes:
The probesare adjusted forthe standard cable with a length of 2m.
Byusing extension cablesforthe probesthe accuracyof the measured relative
humiditydegrades.
Using an additionalextension cable with a length of 2mor4m: no change of the
humidityoffset isnecessary.
Using an additionalextension cable with a length of 6m: set an offset value of –0.8%
in the software SmartGraph.
Using an additionalextension cable with a length of 8mor10m: set an offset value
of –1.8%in the software SmartGraph.
Go into software SmartGraph and performfollowing step:
- instrument ->configuration of instrument
- select the instrument
- sensors -> settings(relative humidity)
- enterthe offset asdescribed above

5 HUMLOG10 THC with Internal Sensors/without Display
General: the hardware of the HUMLOG10 compact is almost identicalto the
hardware of the HUMLOG10 with display. Two LEDs(a red and a green one)are
used asa sub-stitute forthe displayto indicate the operation mode and the alarm.
In addition, you will find close to the serialinterface a start / stop button to switch on
/ off the datalogger.

Start/Stop function: the off / on button enablesthe HUMLOG10 to start and stop
recording. The manualactivation / deactivation of the dataloggerand the
configuration in start/stop orin ring mode are independent.. Bypressing the off / on
button, the HUMLOG10 will start recording ; bypressing it again, the HUMLOG10
will stop etc...
Important: In the start / stop mode, the HUMLOG10 will start recording fromthe
start date on (provided that this date is set in the HUMLOG) no matterif the start /
stop button is being pressed during this time.
Before the HUMLOG startsrecording, it can be activated ordeactivated too via the
on / off button (s. timing diagram).
