OPERATING INSTRUCTIONS
PL-120 T2 THERMOMETER
Item No. 12 34 02
1.
INTENDED USE
This product is designed for temperature measurement and is especially suitable for use in laboratories
and industrial areas. Temperature measurement is done via two temperature sensors. Temperature
can be measured with temperature sensors of type K and J. Measurement readings can be frozen
on the screen. The product can display the minimum, maximum and average readings of a particular
measurement process. Temperature can be displayed in ºC (Celsius), ºF (Fahrenheit) or K (Kelvin).
The product can calculate the difference between two temperature readings and display the result. The
product features an auto-off and a backlight function. Power is supplied by three AAA batteries.
Measurements should not be carried out under unfavourable ambient conditions. Adverse conditions are:
•
Moisture or excessive humidity
•
Dust and flammable gases, vapours or solvents.
•
Thunderstorms or similar conditions such as strong electrostatic fields, etc.
This product fulfils European and national requirements related to electromagnetic compatibility
(EMC). CE conformity has been verified and the relevant statements and documents have been
deposited at the manufacturer.
Unauthorised conversion and/or modification of the device are inadmissible because of safety and
approval reasons (CE). Any usage other than described above is not permitted and can damage the
product and lead to associated risks such as short-circuit, fire, electric shock, etc. Please read the
operating instructions thoroughly and keep them for further reference.

of connected devices.
•
Protect the product from extreme temperatures, direct sunlight, strong jolts, high humidity, moisture,
flammable gases, vapours and solvents.
•
Do not place the product under any mechanical stress.
•
If it is no longer possible to operate the product safely, take it out of operation and protect it from any
accidental use. Safe operation can no longer be guaranteed if the product:
-
is visibly damaged,
-
is no longer working properly,
-
has been stored for extended periods in poor ambient conditions or
-
has been subjected to any serious transport-related stresses.
•
In schools, training facilities, hobby or self-service workshops, handling of electrical devices must be
monitored by trained personnel.
•
When operating on commercial premises, the relevant accident prevention regulations of workers'
compensation boards for electrical equipment must be observed.
•
Make sure there are no devices with strong electric or magnetic fields such as transformers, motors,
cordless telephones and radio-controlled devices in the vicinity of the product as these can influence
the product.
•
Do not switch the product on immediately after it has been taken from a cold to a warm environment.
The condensation that forms might destroy the product. Allow the product to reach room temperature
before switching it on.
Batteries
•
Correct polarity must be observed while inserting the batteries.
•
Batteries should be removed from the device if it is not used for a long period of time to avoid
damage through leaking. Leaking or damaged batteries might cause acid burns when in contact with
skin, therefore use suitable protective gloves to handle corrupted batteries.
•
Batteries must be kept out of reach of children. Do not leave the battery lying around, as there is risk,
that children or pets swallow it.
•
All the batteries should be replaced at the same time. Mixing old and new batteries in the device can
lead to battery leakage and device damage.
•
Batteries must not be dismantled, short-circuited or thrown into fire. Never recharge non-rechargeable
batteries. There is a risk of explosion!
Miscellaneous
•
Repair works must only be carried out by a specialist/ specialist workshop.

OPERATION
•
Do not measure the temperature of live parts or leads, as touching them might
cause a potentially lethal electric shock. Also, the thermometer and sensors
could be damaged.
•
The sensors included with delivery can only be used for measurements in dry
environments and on surfaces with a temperature of > -20 ºC and < +250 ºC. They
are not suitable for use in humid environments or to measure the temperature
of fluids.
•
The accuracy of the gauge is only assured when the thermometer is operated at a
temperature range of +18 ºC to +28 ºC (excluding the temperature sensors).
•
The thermometer (excluding the temperature sensors) must not be used outside
the operating temperature range. Please note the specifications on operating
temperature in the Technical Data section.
•
you can utilize the entire measurement range of the thermometer with optionally
available temperature sensors.
Basic functions
1.
Connect the temperature sensors to ports T1 and T2 on the top of the device. You may also connect
just one temperature sensor. Only one direction is possible. Please note the polarity labelling on the
temperature sensors' plugs and on the side of the ports.
You can also connect temperature sensors of type J to the thermometer; these are optionally
available.
2.
Press the on/off button to switch the device on.
3.
Place the sensors at the locations which you want to measure.
4.
The display will show the temperature readings (T1 top, T2 underneath). If no temperature sensor is
connected, four horizontal bars will be displayed instead of a temperature reading.
5.
Press the CFK button to switch between Celsius (C), Fahrenheit (F) and Kelvin (K).
