Intended Use
The battery-operated, compact data logger DL-100T has an internal temperature sensor, the
DL-120TH additionally an air humidity sensor. The measuring data is recorded automatically at
adjustable intervals from 2s up to 24h. At most 32,000 measuring values (with the DL-120TH
16,000 each for temperature and air humidity) can be saved. This enables data recording over
several years.
A space-saving installation via wall mount is also possible.
The data logger is connected to a computer like a standard USB data carrier and read there.
Data is evaluated graphically with an evaluation program. Data export for table evaluation is also
possible.
In addition, the recorded data can be saved for further processing.
A long-life lithium battery supplies the power. This ensures a very long recording time.
With attached protective cap, the product is spray water-protected and can be used indoors and
outdoors.
Use other than that described above can damage the product and may involve additional risks
such as short circuits, fire and electric shocks.
No part of the product can be modified or rebuilt. It is not authorized to use the device if the hous-
ing is not completely shut.
The data logger must not be operated when it is open, i.e. with an open battery compartment or
when the battery compartment cover is missing. Measuring under adverse ambient conditions
like dust and flammable gasses, vapours or solvents is not admissible.
The safety instructions must be followed unconditionally!

since this could affect the measurement.
Batteries and rechargeable batteries
Batteries must be kept out of the reach of children.
When installing the batteries, make sure to pay attention to the correct polarity.
Do not let batteries/rechargeable batteries lie around openly. There is a risk of batteries being
swallowed by children or pets. If swallowed, consult a doctor immediately.
Leaking or damaged batteries/rechargeable batteries may cause acid burns when coming into
contact with skin, therefore use suitable protective gloves.
Make sure that batteries/storage batteries are not short-circuited or thrown into fire. There is a
risk of explosion!
Never disassemble batteries/storage batteries!
Do not recharge normal batteries. There is a risk of explosion!
In case of longer periods of non-use (e.g. during storage) remove the inserted battery/accumu-
lator to avoid damage through leaking batteries.
Initial operation
The data loggers are protected against spray water with a protective cap and a rubber seal. This
protection allows permanent logging operation also in damp rooms or outdoors.
The protective cap must be removed for changing the battery or reading the saved data via a
computer.
Pull the transparent cap off the device. The protective cap has a tight fit on the data logger
due to the rubber seal. Twist the protective cap carefully back and forth while pulling until it
comes off.
Prior to data recording with the data logger, you have to replace the protective cap tightly again.
Inserting/replacing the battery
Prior to working with the data logger, you first have to insert the enclosed batteries.
1. With a pointed object (e.g. a small screwdriver or similar), open the casing. Lever the casing
off in the direction of the arrow.
2. Pull the data logger from the casing.
3. Turn the data logger around and insert the battery into the battery compartment observing the
right polarity. Observe of the polarity markings in the battery compartment. The two displays
briefly light up for control purposes (alternating, green, yellow, green).
4. Slide the data logger back into the casing until it snaps into place. Now the data logger is ready
for programming.
A battery change is required if the two displays do not light up when starting the measuring
process or when the red „ALM" display (3) blinks in 60 second intervals.
The saved data is not lost in case of a battery change or a breakdown during
recording.
