OS880 Series
Essential Handheld Infrared Thermometer

Introduction

The OS880-Series handheld infrared thermometer is a non-contact temperature sensing thermometer. It measures from -30 to 550°C (-22 to 1022°F). This thermometer features a backlit display that is automatically illuminated when the trigger is pulled and allows working in poor or zero-lighting conditions. The single laser is also automatically active when the trigger is pulled. The laser is located above the IR sensor to locate the center of the area being measured. The meter constantly updates the temperature measurement as long as the trigger is held in and will “hold” on the last temperature seen when the trigger is released. The OS880-Series has adjustable emissivity, min, max, and averaging functions, as well as high and low alarm capability. This safely measures surface temperatures of hot, hazardous, or hard-to-reach objects without contact.

1.1 How it works
This handheld infrared thermometer measures the surface temperature of an object. The unit’s optics sense emitted, reflected, and transmitted energy which is collected and focused onto a detector. The unit’s electronics convert the energy value into a temperature in °C or °F which is displayed on the digital display. A clean line of sight free of dust or mist is needed between the sensor and the object. For increased ease of use and accuracy, the laser pointer makes aiming even more precise.

Measurement:
When taking the measurement, point the thermometer toward the object to be measured and hold the trigger. The temperature will be displayed along with the word “Scan” to indicate that the temperature is constantly being updated on the display. When the trigger is released, the last reading seen will be held on the display. The object under test should be larger than the spot size calculated by the field of view diagram below.

Field of View:
Field of view, or distance to spot ratio, is the size of an area that can be measured from a specified distance. As the distance from the object increases, the spot size of the measuring area becomes larger. Make sure the target is larger than the unit’s spot size. When accuracy is critical, ensure that the target is at least twice as large as the spot size. Please see the field of view diagram for the OS880-Series below.

Emissivity:
Most organic materials and painted or oxidized surfaces have an emissivity of 0.95 (pre-set in the unit). Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate, cover the measured surface with masking tape or flat black paint. Measure the tape or painted surface when the tape or painted surface reaches the material temperature. Please see the Emissivity table below for common emissivity values and adjust accordingly.

Emissivity Table:

Material	Emissivity	Material	Emissivity
Aluminum	0.30	Iron	0.70
Asbestos	0.95	Lead	0.50
Asphalt	0.95	Limestone	0.98
Basalt	0.70	Oil	0.94
Brass	0.50	Paint	0.93
Brick	0.90	Paper	0.95
Carbon	0.85	Plastic	0.95
Ceramic	0.95	Rubber	0.95
Concrete	0.95	Sand	0.90
Copper	0.95	Skin	0.98
Dirt	0.94	Snow	0.90
Frozen Food	0.90	Steel	0.80
Hot food	0.93	Textiles	0.94
Glass (plate)	0.85	Water	0.93
Ice	0.98	Wood	0.94

1.2 Caution
The infrared thermometer should be protected for the following:
– EMF (electromagnetic fields) from arc welders and induction heaters.
– Thermal shock (caused by large or abrupt ambient temperature changes allow 30 minutes for the unit to stabilize before use).
– Do not leave the unit on or near objects of high temperature.
Warning: Do not point laser directly at eye or indirectly off reflective surfaces!

Specifications

Accuracy	±3°C or ±3% of rdg, -30°C to 0°C (-22 to 32°F)

Operating Instructions

3.1 Battery Installation:
Use the thumb and forefinger to pull on the finger grips on either side of the trigger of the thermometer (Figure 1). The battery compartment door will swing down (Figure 2). Insert a 9 Volt alkaline battery into the battery holder (Figure 3). Take care not to pinch the battery wires when closing the battery door back to its original position.

3.3 Operating Steps

Hold the thermometer by the handle grip and point it towards the surface to be measured.
Pull and hold the trigger to turn the thermometer on. The “SCAN” icon will appear on the top line of the display.
The surface temperature being measured will be displayed on the LCD screen.
When the trigger is released, the “HOLD” icon will appear and the last reading seen will remain on the display screen.
The thermometer will automatically turn off after 7 seconds of inactivity.

3.4 Button function
3.4.1 Mode Selection

With the trigger held, press the “MODE” button [3] to cycle through the different modes.
a. “AVG” displays the average temperature reading seen during the session.
b. “MAX” displays the maximum temperature reading seen during the session.
c. “MIN” displays the minimum temperature reading seen during the session.
d. “HAL” shows a High Alarm value (use UP and DN buttons to adjust up or down).
e. “LAL” shows a Low Alarm value (use UP and DN buttons to adjust up or down).
3.4.2 Changing Temperature Units
With trigger [1] held and “SCAN” shown on display, press “T/DN” [4] to toggle between °C and °F.
3.4.3 Adjusting Laser
1) While holding the trigger and “SCAN” activated on display, press the “Laser” button [8] to toggle the single laser dot on and off.
3.4.4 Adjusting Emissivity
With the unit turned “on”, press the “MODE” button [3] a few times to get to the “Є” annunciator which will show the current Emissivity value.
Press the Backlight/UP button [2] to increase value and the “T/DN” button [4] to decrease value.
When the desired value is reached, press “SET” again to lock in the value.
3.4.5 Adjusting High/Low Alarm
With trigger held and “SCAN” activated on the display, press the “Mode” button [3] one press at a time to get to “LAL” (low alarm) or “HAL” (high alarm) annunciator.
Press the Backlight/UP button [2] to increase value and the “T/DN” button [4] to decrease value.

3.5 Locating a Hotspot:
To find a hot spot, aim the thermometer outside the area of interest, then scan across with up and down motions until you locate the hot spot. Turning on the laser will make for more precise targeting.

Maintenance

Lens cleaning: blow off loose particles using clean compressed air. Gently brush the remaining debris away with a moist cotton cloth.
Case cleaning: clean the case with a damp sponge/cloth and mild soap.
Note: Do not use solvent to clean the lens and do not submerge the unit into water or any other liquid.
