HOW THE THERMOMETERS WORK

Infrared thermometers measure the surface temperature of an object. The thermometer’s optics sense emitted, reﬂected, and transmitted energy, which is collected and focused onto a detector. The unit’s electronics translate the signal into a temperature reading which the unit displays .

OPERATING THE THERMOMETER

Temperature Measurement

The thermometer will turn on when you pull the trigger and also features an auto-off function that automatically powers down the thermometer after 8 seconds of inactivity.

To measure temperature, point the thermometer at an object and pull the trigger. You can use the laser pointer to help aim the thermometer. Pull and hold the trigger when measuring the target surface. When release the trigger, the display will hold the reading for 8 seconds. Be sure to consider distance-to-spot size ratio and ﬁeld of view. The laser is used for aiming only and is not related to temperature measurement.

K-Type Thermocouple Measurement

To avoid electrical shock or personal injury, do not connect the thermocouple contact probe to live

electrical circuits.

The thermometer comes with a bead K-type thermocouple probe. K-type thermocouple is connected to the thermometer via TC-K input connector located on right side of the thermometer. The probe can be used simultaneously while the thermometer is taking non-contact measurements.

1. Press YELLOW button to enter T-C mode. The display shows OL before the measurement is made.

2. Connect the K-type thermocouple to the thermometer via TC-K input connector located on right side of the thermometer. Press the trigger to start measuring. Secondary display shows the measurement reading.

3. Release the trigger, the reading is kept on display (display hold: 8 seconds)

Locating a Hot or Cold Spot

To ﬁnd a hot or cold spot, aim the thermometer outside the target area. Then, slowly scan across the area with an up and down motion until you located the hot or cold spot.

Distance and Spot Size

As the distance (D) from the target being measured increases, the spot size (S) of the area measured by the instrument becomes larger. The spot size indicates 90% encircled energy.

Field of View

Make sure that the target is larger than the spot size. The smaller the target, the closer you should be to it.

Emissivity

Emissivity describes the energy-emitting characteristics of materials. Most organic materials and painted or oxidized surfaces have an emissivity of about 0.95. If possible, to compensate for inaccurate readings that may result from measuring shiny metal surfaces, cover the surface to be measured with masking tape or ﬂat black paint (<150°C / 302°F ) and use the high emissivity setting. Allow time for the tape or paint to reach the same temperatures as the surface beneath it. Measure the temperature of the tape or painted surface.

If you cannot use paint or use tape, then you could improve the accuracy of your measurements with the emissivity selector. Even with emissivity selector, it can be difﬁcult to get a completely accurate infrared measurement of a target with a shiny or metallic surface.

The thermometer allows you to adjust the emissivity for the type of surface you’re trying to measure the

temperature of. Use a different setting for your application by referring to the Table of Surface Emissivity.

Reminders

1. Changes of surrounding ambient temperature can result in inaccurate reading, allow time for the instrument to adopt the change of ambient temperature before use. Speciﬁed accuracy applies after 30 minutes when the instrument changes to a different temperature environment an inaccurate.

2. The instrument cannot measure through transparent surfaces such as glass. It will measure the surface temperature of the glass instead.

3. See Table of Surface Emissivity for use in measuring shiny or polished metal surfaces (stainless steel, aluminum, etc.).

4. Steam, dust, smoke, etc., can prevent accurate measurement by obstructing the instrument’s optics.

TYPICAL MEASUREMENTS

This section describes a variety of measurements often performed by technicians.

Reminder:

• User could select to turn on or off the backlight and laser whenever you are making readings with the

thermometer.

• Relatively high emissivity normally means emissivity setting of about 0.95.

• Relatively low emissivity normally means emissivity setting of about 0.30.

• When user cannot identify the emissivity of the object to be measured, user could cover the surface to be

measured (temperature >150°C) with black electric tape (emissivity of about 0.95). Allow time for the tape

to reach the same temperature as the object to be measured. Measure and record the temperature of the

tape.

Aim the thermometer to the object to be measured, adjust the emissivity setting to make it as the same temperature as the tape. At this time, the thermometer emissivity setting is close to the emissivity of the object to be measured,

measurement can be taken.

Testing Contactors (Starters)

1. Press SET to select emissivity. Press / to select relatively low emissivity for bright contacts, or 0.7 mid level for darkened contacts.

2. Press YELLOW button to select MAX.

3. Measure line and load side of one pole without releasing trigger.

4. A temperature difference between the line and load sides of a pole indicate increased resistance of one point and a contactor may be failing.

Testing Enclosed Relays

1. Press SET and then press / to set emissivity to relatively low for un-insulated connectors or relatively high for plastic encased relays or for Bakelite enclosed relays or insulated connectors.

2. Press YELLOW button to select MAX.

3. Start to scan.

4. Measure the relay casing, looking for hot spots.

5. Measure electrical connections on relay terminals looking for hot spots.

Testing Fuses and Buss Connections

1. Press SET and then press / to set emissivity to relatively high for paper covered fuse body or insulated connections.

2. Press YELLOW button to select MAX.

3. Scan the paper covered length of fuse.

4. Without releasing the trigger, scan each fuse. Unequal temperatures between fuses may indicate voltage or amperage imbalance.

5. Press SET and then press / to set emissivity to relatively low, for metal fuses and caps and insulated buss connections.

6. Press MODE to select MAX.

7. Scan each end cap on each fuse.

Note: Unequal temperatures or a high temperature indicates loose or corroded connection through the fuse buss spring clip

Testing Electrical Connections

1. Press SET and then press / to set emissivity to relatively low for un-insulated connectors or buss connections or relatively high for insulated connections.

Note: Conductors are typically smaller than the thermometer’s spot size.

If the spot size is bigger than the connector, the temperature reading is the average within the spot.

2. Scan the conductor, moving toward direction of electrical connector (quick connector, wire nut, buss connection, etc.).

Scanning Walls for Air Leaks or Insulation Deﬁciencies

1. Turn off heating, cooling, and blower.

2. Press SET to select emissivity. Press window surfaces.

3. Press YELLOW button to select MIN when opposite side of wall is at lower temperature and or select MAX when opposite side of wall is at higher temperature.

4. Measure an interior partition wall surface temperature.

5. Do not release the trigger. Record this temperature as your baseline (or benchmark) for a “perfectly” insulated wall.

6. Face the wall to be scanned. Stand 1.5m away to scan a 4cm spot on the wall.

7. Scan horizontal rows of wall from top to bottom, or horizontal rows of ceiling from wall to wall. Look for greatest deviations from baseline temperature to identify problems. This completes the insulation test scan.

Turn on the blower (no heat, no cooling) and retest. If test results with the blower on are different than results with the blower off, this may indicate air leaks in conditioned envelope walls. The air leaks are caused by duct leaks that create a pressure differential across the conditioned space envelope.

/ to select emissivity relatively high for painted surfaces or

Testing Bearings

Warning

To avoid injury when testing bearings:

1. Do not wear loose clothing, jewelry, or anything around neck when working around moving parts such as motors, belts, blower, and fans.

1. Press SET and then press

2. Press SELECT to select MAX.

3. Enable motor and allow it to reach steady state operating temperatures.

4. Disable the motor if possible.

5. Measure the two motor bearing temperatures.

6. Compare the two motor bearing temperatures. Unequal temperatures or a high temperature can indicate a lubrication or other bearing problem that is resulting from excess friction.

7. Repeat the sequence for the blower bearings.

/ to select relatively high emissivity.

Testing Belts and Sheaves

1. Press SET and then press / to select relatively high emissivity.

2. Press SELECT to select MAX.

3. Enable the motor and allow it to reach a steady state operating temperatures.

4. Aim the thermometer at the surface to be measured.

5. Start recording temperature.

6. Slowly move the thermometer up the belt toward second sheave.

• If belt is slipping, sheave temperature will be high from friction.

• If belt is slipping, belt temperature will remain high between sheaves.

• If belt is not slipping, belt temperature will reduce between sheaves.

• If inner surfaces of sheaves are not a true “V” shape, this indicates belt slippage and will continue to

operate at elevated temperatures until sheave is replaced.

• Sheaves must be properly aligned (include “pitch & yaw”) for belt and sheaves to operate at

appropriate temperatures. A straight edge or taut string, can be used to check alignments.

• Motor sheave should operate at a temperature consistent with blower sheaves.

• If motor sheave is at a higher temperature at motor shaft than at outer circumference, belt is probably

not slipping.

• If outer circumference of sheave is at higher temperature than sheave at motor shaft, then belt is probably

slipping and sheaves may be misaligned.

Checking Hydronic Radiant Heat Applications

1. Press SET and then press / to select relatively high emissivity.

2. Press YELLOW button to select MAX.

3. To locate radiant heat tubes in ﬂoor, temporarily elevate the loop temperature to create hotter spots for identifying tubing runs.

4. Before releasing trigger, press YELLOW button to toggle between MIN, MAX, DIF ﬂoor temperatures and record the temperature for future comparison and trending under similar conditions.

FONCTIONNEMENT DES THERMOMÈTRES

Les thermomètres infrarouges mesurent la température de surface d'un objet. L'optique du thermomètre

détecte l'énergie émise, réﬂéchie et transmise qui est collectée et focalisée sur un détecteur. L'électronique de l'appareil convertit le signal dans la lecture de température qui apparaît sur l'afﬁcheur.

UTILISATION DU THERMOMÈTRE Mesures de température

Le thermomètre se met sous tension lorsque vous appuyez sur la gâchette. Le thermomètre se met hors tension lorsqu'aucune activité n'est détectée pendant 8 secondes.

Pour mesurer la température, pointez le thermomètre sur un objet et actionnez la gâchette. Vous pouvez utiliser le pointeur laser pour mieux viser avec le thermomètre. Actionnez et maintenez la gâchette pour mesurer la

surface ciblée. Quand vous relâchez la gâchette, l'écran maintient l'afﬁchage de la mesure pendant 8 secondes. Veillez à respecter la distance par rapport à la taille du point focal et le champ de visée. Le laser n'est utilisé que pour viser et n'a pas d'incidence sur la mesure de température.

Le thermomètre possède une fonction d'arrêt automatique qui met le thermomètre automatiquement hors tension après 8 secondes d'inactivité. Actionnez la gâchette pour mettre le thermomètre sous tension.
