Omega OS950 manual Temperature Measurement of Moving Targets, High Temperature Targets

2.4.2Temperature Measurement of Moving Targets

To measure moving targets that are not possible to touch, use the following procedure:

1.Press and hold the MEASURE button.

2.The display will briefly show [8888].

3.Bring the nosepiece as close as possible to the target, preferably within 1/32 inch (1 mm). **

4.The display may or may not change, but the "beeping" sound will indicate that measurements are being made.

5.Record the temperature from the display.

6.Release the MEASURE button. The last reading will remain locked on the display for 10 seconds after releasing the button.

**If the surface is metallic, be sure to mark it as described in the Measurement Tips section in Chapter Three.

2.4.3 High Temperature Targets

When using the OS950™ to measure high temperature tar- gets, above 100 °F, quickly touch the target's surface -- one second is long enough to get an accurate reading.

Follow the procedures described above under 2.4.1 General Operation (see pg. 5). If the OS950 makes contact with a hot surface for an extended time (10 seconds or more) the target will conduct heat. Although this will not harm the unit, the indicated temperature may be a few degrees too high. Allow a few minutes between readings for the nosepiece to cool down and stabilize.

If the OS950 makes contact with a hot surface and an error message [HI] shows on the display remove the instrument from the object immediately.

2.5 MAX Mode Temperature Measurements

Use this measurement mode when making contact with the target or when the target is large. The OS950 is a wide- angle thermal scanner with a fixed emissivity of 0.9. The target's temperature is continuously displayed and updated 10 times per second for as long as you hold the MEASURE button down.

The OS950 displays the average temperature of everything within the sensor's field of view measurement area. The size of the measuring area depends on the distance of the device from the target. The OS950 has a 1:1 field of view, which means that this unit will measure a 1"diameter target area when the device is 1" from the target.

2.5.1 General Operation

For continuous temperature measurement of a target or for temperature measurement at a distance, use the following procedure.

1.Determine the appropriate measurement distance from your desired target. Best measurements are made when the OS950 is in contact with the target.

2.Make sure the MODE switch is on MAX.

3.Point the nosepiece at the target.

4.Press and hold the MEASURE button.
