Omega Speaker Systems OS533E, OS532E, OS524E Changing the Temperature from F to C or vice Versa

2Using the Handheld Infrared Thermometer

2.3.7Changing the Temperature from °F to °C (or vice

versa)

During the time the thermometer displays either d_F, d_M, MAX, MIN, dIF, AVG or thermocouple temperature, press the C F key to change all the temperatures from °F to °C or vice versa.

2.3.8 Turning on the Display Backlighting

During the time that the thermometer displays either d_F, d_M,

LSR, MAX, MIN, dIF, AVG, or TC temperatures, press the key to turn the display backlighting ON/OFF.

2.3.9 Thermocouple Input (OS532E, OS533E, OS534E)

LCK

°F

The thermometer accepts thermocouple input. It displays thermocouple temperature and the target temperature (via infrared) simultaneously. This function provides an accurate method of determining an unknown emissivity.

•To Determine an unknown target emissivity

1.Connect a contact thermocouple probe (Type K) to the thermometer as shown in Figure 1-3.

2.Measure the object temperature using the thermocouple probe.

3.Aim at the object and measure the temperature via infrared.

4. Press and hold the FUNC key until the Emissivity Display mode (E) appears.

5.Set the emissivity by pressing the or C F keys until the temperature reading matches the thermocouple temperature measurement.

6.The thermometer now displays the correct object emissivity.

"TC--- is” is displayed when the thermocouple input is open or out of range (0 to 1600°F).
