External probe operation. Connect the Pt100 resistance thermometer to the appropriate 
connector. Switch the unit on and press the [Probe] key. The “EXT” message will be 
displayed on the lower display for Pt100 readings. 
Hold measurement. Press the [HOLD] key to freeze the displayed temperature. The hold 
value will be displayed in lower display. On the main display the temperature is that actually 
measured. Press the key again to refresh the Hold indication.
The Hold indication is refreshed by pressing the trigger for more than 1 sec with the unit in 
measuring mode and releasing the trigger. Switch the OSP100 off by pointing the unit to 
the target to recall the last value when you switch the unit on.
Select Average (AVG), Minimum (MIN) and Maximum (MAX) values. Press the [Min/Max] 
key until the appropriate message is displayed. The unit will refresh the values of each 
nd
measurement from the power on. To reset the values, press the [2 ] key or switch the unit 
off and on.
nd
Emissivity adjustments. Press in sequence the [2 ] and [Set e] keys to change the emissivity 
from 0.30 to 1.00 with 0.01 resolution. On the lower display the set value is shown. Press 
the [UP] and [DOWN] keys to increase and decrease the emissivity. Press the [ENTER] key to 
store and return on the normal mode measurement.
nd
Set low (LAL) and high (HAL) alarms. Press in sequence the [2 ] and [HI] keys to change 
the High alarm set point.. “HAL” will be seen on the display. The stored High alarm will be 
displayed. The High alarm level is to be set by adjusting the [UP] or [DOWN] keys. Press the 
[HI] key to enable/disable the acoustic alarm. Press the [ENTER] key to store the displayed 
nd
value and return to normal mode. Press in sequence the [2 ] and [LO] keys to change the 
Low alarm set point..“LAL” will be seen on the display. The Low alarm level is to be set by 
adjusting the [UP] or [DOWN] keys. Press the [LO] key to enable/disable the acoustic alarm. 
Press the [ENTER] key to store the displayed value and return in normal operation mode. 
When the measurement is inside the programmed alarm band, the “LAL” or “HAL” symbol 
will be lit and an intermittent beep will be emitted.
To take a temperature reading, point the unit at the target you wish to measure. Push and 
keep the trigger pushed. The current temperature reading is displayed. Last reading before 
previous switching-off is displayed in lower display. Release the trigger. A “Lock” symbol on 
the LCD will be displayed and the Hold value is refreshed. OSP100 will remain switched on 
for 40 seconds. The time will reset if a key is pressed or a serial communication message is 
sent.. Press and release quickly the trigger to switch the instrument off. 
The OSP100L and 100XL models can be supplied with a laser sighting with either a “laser 
dot” to read the target area center or with a “laser circle” to read the target area. Press the 
[*] key to enable/disable the laser. The message “LAS EN” or “LAS DIS” will be displayed. 
When enabled, the laser can be switched on by pressing the trigger button for more than 
1 sec. The laser will automatically switch off when the trigger button is released. The 
emission indicator symbol (*) will appear on lower display.
nd
Press in sequence the [2 ] and [*] keys to change the laser beam mode between 
Continuous and Flashing (to increase battery expected life) mode.
Press the [Lamp] key to switch back-light on or off.
nd
Press in sequence the [2 ] and [°C/°F] keys to change the engineering units between °C 
and °F.
The OSP100 is the ideal tool for periodic process monitoring and for measuring 
temperature quickly and easily, by contact with the target or from distance. An optional 
laser pinpointing method simplifies the identification of the measuring surface area.
The OSP100 is the essential tool for the prevention of a variety of temperature related 
equipment or process malfunctions. It can prevent serious damage to bearings, motors, 
valves, electrical switches and distribution conductors, cooling or steam traps, thermal 
insulation deterioration, hot spots, engine performances, extrusion heads, depleted 
refrigeration system, etc.
The instrument is rugged, accurate and compact for fast and easy periodic process 
monitoring, to control quality and/or supervise production phases of cooked and 
refrigerated foods.
