1. General
Welcome to the manual for the hand held infrared pyrometer. You can
measure surface temperatures between 150°C (302°F) and 1800°C (3272°F)
without contact using this digital, battery powered pyrometer.
A laser pilot light marks the center of the measuring spot.
Caution!
Do not look into the laser beam!
It may damage your eyes.
The instrument has an illuminated LCD display, a serial RS-232-interface and a
socket for a 9 V battery charger.
This portable infrared thermometer is specialy made for the glass industry.
With a fixed spectral range at 5,14 µm the instrument is perfectly suitable to
measure to measure the temperature on glass surfaces.
On pure metal or other strong reflecting surfaces accurate measurements are
not possible.
Caution!
Prevent any contact between the lens and acidic substances
to avoid the generation of toxic gases!

up the lock-key.
All functions can be managed using the keys on the keyboard. The laser can
be turned on or off with the key marked by a laser symbol. The key marked
“PAR” is the Parameter key for choosing the parameter to be used or
adjusted (i.e. MAX or MIN or EMI Parameter for emissivity). The chosen
function always appears in the small display. Use the “up” or “down” keys for
adjusting or selecting a parameters value.

3.2. Setting up the instrument
The instrument is powered by a 9 V Alcaline-Manganese battery (IEC 6LR61) or
a 9 V rechargeable battery with the same dimensions, fitted into the handle. To
replace the battery, first remove the screw in the batterycover and then pull out
the battery cap. Fit the battery clip to the terminals on the battery, ensuring the
polarities are correctly matched. Replace the battery cap and the screw. The
pyrometer is now ready to use.
To prevent data losses, the battery change should only be done if the
instrument is not working.
Caution!
Do not use the battery chargerif a non-
rechargeable battery is fitted!
When using a rechargeable battery, it can be recharged via the socket for the
battery charger, being available as accessory.
The typical changing current is 10 mA.

3. How to operate the instrument
3.1 Display and Keyboard
When the battery power is low the symbol will flash on the display.
The instrument can still be operated for a short time. If the battery power is
too low for the instrument to operate correctly, then it will switch off
automatically. For saving battery life it is advisable to use the laser pilot light
only temporarily for aiming at the target and then turning it off.

After an internal check (about 0.5 s), the measured temperature appears on
the display. At the RS-232-interface the values are also supplied at a time base
of 100 ms.
After releasing the trigger the last measured value is displayed, the output via
interface stops.
In the upper right corner of the LCD display the “HOLD” symbol appears. The
instrument remains for another 10s in standby and then turns off automatically.
After switching on the instrument again, the MAX, MIN, DIF and AVG values
are reset.

The spot diameter for distances longer than 650 mm can be calculated
according to the following formula:
M = 0 .05 * a - 20 (all values in mm)
M - Diameter of the spot
a - Distance between targeted object an instrument
The close-up lens (accessory) reduces the spot diameter to 2.3 mm at a
distance of 96 mm.
Then the emissivity ehas to be set according to the following formula:
(with e = the real objects emissivity)

e= 0.72 * eObject
When using the close-up lens the spot diameter for distances larger than
96 mm can be calculated according to the following formula:
M = 0.23* a - 20 (all values in mm)
M - Diameter of the spot
a - Distance between targeted object and instrument

3.5. Laser sighting
The laser pilot light can be switched on or off by pressing the key marked
with the laser symbol. The laser beam marks the center of the target spot. If
the laser is turned on the laser symbol in the center of the upper row on the
display flashes.
Caution!
Do not look into the laser beam! It may damage your eyes.
3.6. Setting a Parameter
The different parameters can be chosen by repeatedly pressing the “PAR”-
key until the requested parameter appears in the parameter display.

3.6.1. Emissivity
The emissivity is the amount of heat radiation from the measured object –
compared with an ideal black object. To measure the temperature of any
surface accurately, it is necessary to know its emissivity and to set this value
correctly.
27
3.6.2. MAXimum and MINimum function
In addition to the actual temperature being shown on the large display, the
maximum (MAX) or minimum (MIN) temperature can be shown on the small
display.The MAXimum function is especially useful for finding hot spots on
larger areas by scanning this area with the pyrometer. Even small hot spots
can be registered because the MAX display reacts faster than the NORMAL
function (response time 150 ms). This method can also be used for fast
moving objects.

To change a parameter value just press the „up” or “down” key until the
value required is shown in the small display.
The measuring functions (NORMAL, MAX, MIN, AVG, DIF) remain set until
the user chooses a different function. Any change will be saved even when
the instrument has turned off automatically.
After changing a parameter function (EMI, HI, C/F), the instrument
automatically returns to the NORMAL mode after 10 s.
