Safety precautions

This instruction manual contains warnings and safety rules which must be observed by the user to ensure the safe operation of the instrument and retain it in a safe condition. Therefore, read through these operating instructions before using the instrument.
1-1.   DANGER The connector for the thermocouple is not insulated. Do not make measurements using a thermocouple when there is a risk of electrical shock hazard.
1-2. WARNING KEW5515 is one of the portable laser applied instruments which are regulated by the consumer product safety law.

• Do not look directly into the laser.
• Do not point the laser directly at persons or animals.
• When measuring a reflective object such as mirrors, take extra caution so as not to look at diffuse reflections.
• Keep out of reach of child or person who doesn’t have the Product handling knowledge.
• Use the Product only as specified. Do not disassemble or modify the Product.

1-3. CAUTION Please follow the precautions below for use to keep the instrument’s functions properly and to enable accurate measurement.

• Do not contact this product with a measuring object. This is a contactless thermometer. Contact with a hot section may cause unrepairable damages or inaccurate readings.
• Do not damage the measuring window (plastic lens). Do not let a foreign object penetrate the measuring window, or drop a hard object on the measuring window.
• This instrument applies a precise optical system.
• Do not give an excessive shock to the instrument. Do not bring the instrument closer to an electrostatic object.
• The emissivity of this instrument can be selected. When the emissivity setting is different from that of a measuring object, an inaccurate reading will occur.
• The sudden changes in the ambient temperature will cause inaccurate readings. Wait a while to let the temperature of the instrument stabilize, and then measure.
• Remove the battery from the instrument, if the instrument is not in use for a long period or is put in storage.

1-4. Environmental precautions

• Do not use or store the instrument in a location where the instrument is exposed to direct sunlight, dust, lampblack, and corrosive gas, or where the temperature and/ or humidity is high. Otherwise, the measuring window gets soiled or deteriorated, which causes inaccurate readings.
• This instrument is not water-proof. Do not use in water or liquid nor make measurements or store it where it may get wet.
• Keep the instrument away from an object which radiates a strong electromagnetic wave.

1-5. Maintenance
Enclosure
Clean it with a soft cloth. To remove heavy stains, wipe it with a cloth wrung out with diluted neutral detergent.
Cautions: Do not use chemical agents such as thinner, benzine or alcohol since these may cause a crack or fog on the surface of the measuring window, and consequently it may change the infrared radiation transmittance of the plastic lens.
1-6. Relation of distance and measuring diameter
The relation between the distance and measuring diameter is as follows. However, the ratio between distance and measuring diameter varies depending on the distance. The more the distance increases, the larger area is needed.

Features

This is a contactless handheld infrared thermometer. Temperature measurement with a K-type thermocouple is also possible.
Alarm function
The upper and lower temperature limits can be set. The red blinking backlight indicates that the measured value is below or over the pre-set limits.
Auto-power-off function
To save battery life, the power is shut off automatically if no key is pressed for 6 seconds.

Getting started

5-1. A measurement model and parameter setting mode
Pull the trigger on the instrument to take a measurement. Press the F button (Function button) to use other functions. The main display shows measured values and the sub-display shows values obtained with each function. The following flow chart shows the sequence and corresponding action.

Measurement mode

• SCAN Shows measured values.

• MAX Shows the maximum value taken during one measurement on the sub-display.

• MINShows the minimum value taken during one measurement on the sub-display.

• AVGAverages the values taken in one measurement and shows it on the sub-display.

• TC Shows measured values using K-type thermocouples.

• EMS Shows emissivity. (P. 10) Use the cursor buttons to alter emissivity.

• HAL Shows the upper limit for alarm. (P. 8) Use the cursor buttons to alter the limit value. The red backlight blinks when a measured value exceeds this limit.

• LALShows the lower limit for alarm. (P. 8) Use the cursor buttons to alter the limit value. The red backlight blinks when a measured value falls behind this limit.

• Auto power-off function activates in 6 seconds. When the display becomes blank due to this power-off function, pull the trigger.

5-2. Other functions

• K-type thermocouple measurement
  Plug a K-type thermocouple into the connector for the thermocouple, and press the function button to select the TC function. Measured values using a thermocouple are displayed on the sub-display.

• Alarm function
  The red backlight blinks when a measured value exceeds or falls behind the values which are set on HAL and LAL functions. On both functions, it is possible to enable or disable the buzzer sound.

• HOLD function
  The measured value is held and displayed for 6 seconds after releasing the trigger.

• Low battery warning
  A battery mark appears when the battery voltage becomes low.

Battery replacement

When the battery is low, the battery mark **** appears on the display. Replace the battery with a new one. When nothing is displayed on the display if attempted, it may also be battery exhaustion. Replace the battery with a new one. Open the battery cover as the below figure shows, insert a new battery with correct polarity, and then close the cover.

Setting emissivity (reference)

The quantity of infrared emitted radiation from objects depends on the objects’ material, surface conditions, measuring temperatures, and so on. The table below shows the emissivity of some objects. Please note that these values are just for reference. Please also refer to the estimated emissivity using the separately sold black body tape MODEL8085.

Material

| Emissivity| Material|

Emissivity

---|---|---|---
Water, Ice| 0.98| Cloth, Fabric (colored)| 0.95
Soil| 0.92 to 0.96| Leather, Fur| 0.96
Concrete (wet)| 0.96 to 0.98| Human skin| 0.99
Concrete (dry)| 0.91 to 0.95| Vegetable, Fruit| 0.98
Ceramics| 0.85 to 0.95| Dough| 0.98
Stone, Asbestos| 0.92| Meat| 0.98
Plastics| 0.90 to 0.95| Copper oxide| 0.50 to 0.60
Rubber (black)| 0.95| Ferric oxide| 0.70 to 0.80
Wood| 0.98| Painted surface| 0.80
Paper| 0.92| Tile| 0.80

Estimated emissivity using the black body tape
If a measuring object accepts sticking of adhesive tape, stick a piece of the black body tape (emissivity: 0.94) to the object, and measure the temperature after setting the emissivity to 0.94.

• Black body is a substance that absorbs all incident radiation: no transmission and no reflection and would have an emissivity value of 1.
• Infrared thermometers can easily measure temperature from a distance with safe. They can be used for electrical or equipment maintenance, building control and process monitoring, and other applications.
