1. Safety Precautions
This product complies with the requirements of the following
European Community Directives: 2004/108/EC (Electromagnetic Compatibility) amended by 2004/22/EC (CEMarking).
Pollution degree 2.
To ensure safe operation of the equipment and eliminate the
danger of serious injury due to short-circuits (arcing), the
following safety precautions must be observed.
* Do not operate the meter before the cabinet has been
closed and screwed safely.
* Check test leads and probes for faulty insulation or bare
wires before connection to the equipment.
* Comply with the warning labels and other info on the
equipment.
* Keep the equipment dry.
* CAUTION! Repeated sharp flexing can break the
thermocouple leads. To prolong lead life, avoid sharp
bends in the leads, especially near the connector.
* Do not subject the equipment to direct sunlight or extreme
temperatures, humidity or dampness.
* Do not subject the equipment to shocks or strong
vibrations.

* Do not operate the equipment near strong magnetic fields
(motors, transformers etc.).
* Keep hot soldering irons or guns away from the equipment.
* To avoid electrical shock, do not use this instrument when
voltages at the measurement surface exceed 24V AC or
DC.
* To avoid damage or burns, do not make temperature
measurement in microwaves ovens.
* Allow the equipment to stabilize at room temperature
before taking up measurement (important for exact
measurements).
* Replace the battery as soon as the battery indicator “BAT”
appears. With a low battery, the meter might produce false
reading that can lead to personal injury.
* Fetch out the battery when the meter will not be used for
long period.
* Periodically wipe the cabinet with a damp cloth and mid
detergent. Do not use abrasives or solvents.
* The meter is suitable for indoor use only
* Do not store the meter in a place of explosive, inflammable
substances.
* Do not place the equipment face-down on any table or
work bench to prevent damaging the controls at the front
* Do not modify the equipment in any way
* Opening the equipment and service- and repair work must
only be performed by qualified service personnel

4. Operating Instructions
4.1. Selecting the temperature scale
Readings are displayed in either degrees Celsius (°C) or
degrees Fahrenheit (°F). When the thermometer is turned on, it
is set to the temperature scale that was in use when the
thermometer was last turned off. To change the temperature
scale, press one of the following keys °C or °F (additional
P 5110 is supplied with: K).
4.2. Selecting the display resolution
The thermometer allows two choices of resolution:
high resolution: 0.1°C or 0.1°F
low resolution: 1°C / 1°F (1 K: only P 5110)
To select the alternate display resolution, press the
corresponding “0.1°/1°” key (P 5115) / (P 5110: 0,1° or 1° key).
4.3. MAX Mode
Pressing the Max key to enter the MAX mode. The thermometer then records and updates the maximum absolute value
and the MAX annunciator appears on the display. Pressing the
MAX key again to exit the MAX recording mode.
-21-

For breading the auto. updating of the saved value (new maxvalue shouldn’t be saved), press button "HOLD". For returning
to auto. updating during a measuring of a new Max-value press
"HOLD"-button again.
4.4 HOLD Mode
Pressing the HOLD key to enter the Data Hold mode, the
“HOLD” annunciator is displayed. When HOLD mode is
selected, the thermometer held the present readings and stops
all further measurements.
Pressing the HOLD key again cancels HOLD mode, causing
the thermometer to resume taking measurements.
4.5. Backlight Mode
Pressing the Backlight key to turn on the LCD-backlighting
Function. Pressing the Backlight key again to turn off the LCDbacklighting function
4.6. Tc (Temperature Compensator) (only P 5110)
Checking Mode.
Pressing and hold the "Tc" key to enter the temperature
compensator-checking mode. The thermometer will display the
temperature inside.
-22-

4.7. Preparation
1. Ensure battery is in place, if LCD-display shows the battery
symbol, the battery should be replaced.
2. Make sure all function keys are set properly. (HOLD)
switch is on an "OFF" position, make sure no "DATA-
HOLD" displayed on LCD.
3. Inspect whether temperature probe has been placed
securely in the temperature outlet, (the "+" outlet of
temperature probe should be connected to the "+" of the
temperature outlet, the "-" outlet of the temperature probe
should be connected to the "-" of temperature outlet).
4.8. Measurement
Temperature measuring:
1. Turn on the thermometer
2. Connect the outlet of test probe "K-Type" to the outlet of
temperature outlet.
3. Measure environment temperature with temperature probe,
the reading will appear on LCD.
-23-

4.9. Adjustment for T1-T2 measurement (only P 5115)
The choice of the input connectors with the correspond
indicated buttons T1, T2 or T1-T2 at the unit. To measure the
differential temperature connect the thermocouples to the
inputs and press “T1-T2”. The indicated temperature value is
the difference between T1 and T2.
Remark:
* For an accurate reading of T2, with liquid temperature
probe (see Fig. 7)
* When the superficial temperature is taking, the top of
temperature probe should have a close contact with the
surface to be measured (see Fig. 8).

4.10. Battery Replacement
Power is supplied by a 9 V “transistor” battery (NEDA 1604,
IEC 6F22). The battery sign appears on the LCD when
replacement is needed.
To replace the battery, remove the screw from the back of the
meter and lift off the battery cover. Remove the battery from its
contacts.
Caution! Batteries, which are used up dispose duly. Used up
batteries are hazardous and must be given in the for this being
supposed collective container.
4.11. Statutory Notification about the Battery Regulations
The delivery of many devices includes batteries, which for
example serve to operate the remote control. There also could
be batteries or accumulators built into the device itself. In
connection with the sale of these batteries or accumulators, we
are obliged under the Battery Regulations to notify our
customers of the following:
