Preface

To use the thermometer correctly and safely, please keep the following safety measures for the operation and storage of the thermometer.

！

１ Wo rking conditions and environment

● The thermometer is designed as a handheld type. Use a tripod or a simple type universal head for long term or fixed mounting measurement.

● The working temperature range of the thermometer is 0 to 50 °C. (No dew condensation)

● Do not use the thermometer in dusty places, etc. Remove the dust after using it.

(As for the cleaning of cover glass, refer to the clause of "9.3 Cleaning of co ver glass".)

● Be careful not to give vibration or impact to the thermometer .

● For preventing the consumption of the batteries, turn the Power Supply Switch of the thermometer off when it

is not used.

● As a glass can not transmit the infrared ray in the measuring wavelength of the thermometer, when the thermometer measures an object through the glass, the surface temperature of t he glass is measured.

(For Model IR-AHT only)

● When the ambient temperature changes rapidly, the measured value may be influenced. When the thermometer has been brought to a place where the ambient temperature is greatly different from the former place, leave the thermometer for one hour and then st art the measur ement. (For Model IR-AHT only)

２ Storage

● Do not store the thermometer in hot and humid places. Make sure to store the thermometer with the lens

cap. Recommend to stores the thermometer in room temperature with a d ry pill.

● Do not leave the thermometer in extreme high ambient temperature such as beside a rear window or inside of a trunk of cars. The thermometer may have troubles.

● When the thermometer is not used for 2 weeks or more, take out the batteries from it. Otherwise, the thermometer may be damaged by liquid leakage of the batteries.

● When the thermometer has any trouble, please contact to CHINO' s sales agent.

stop is held on the internal and external displays.

5.2 Continuous measurement

For the continuous measurement, press ON/OFF key while pressing MEASURE key to turn the power supply on. Press MEASURE key to start the measurement. The measurement is continued until MEASURE key is pressed again.



Reference

・Batteries are consumed abruptly on the continuous measurement．

It is recommended to use the AC adapter Model IR-VHR (option) for the continuous measurement.

5.3 Auto power off

The back-light for internal display lights out in 10 seconds after the stop of measurement. On the continuous measurement, it lights out in 10 seconds after the start of measurement. For lighting the back-light again, press ENT key. The back-light lights for 10 seconds.

For saving the battery life, the power supply is turned off automatically if this thermometer is not operated for 5 minutes

5.4 Cautions on measurement

Warning



・Never directly face the objective lens to the sunlight for protecting your eyes and the detecting element. ・Set the beam attenuation filter selector knob to the beam attenuation side in

advance (in case of Model IR-AHS or IR-AHU) for protecting your eyes on the measurement of object exceeding 1500oC.

・However , when you feel glare on the measurement of objects lower

then 1500 oC, set the beam attenuation filter selection knob to the beam attenuation side in advance.

Beam attenuation

！

Caution

・Light path

Be careful not to introduce water drops, dust particles, smoke, steam, or other foreign substances into the light path between the object measured and the objective lens of this thermometer.

・Interference causing high indication

Be careful not to apply the direct sunlight, light of an incandescent lamp, flame or other thermal radiation to the object measured and the objective lens of this thermometer.

・Abrupt change of ambient temperature

Model IR-AHT uses a thermopile as its detecting element. If the ambient temperature changes abruptly, it takes time until the indication is stabilized.  If your thermometer is Model IR-AHT and it has been brought into a place where a temperature difference is noticeable, leave the thermometer for about one hour before starting the measurement.

5.5 Measuring

This thermometer has various measuring parameters. The list of parameters is shown in [11. List of starting modes/screens]. By pressing MODE key when the measurement screen is displayed, the measuring parameter programming screen is appears with the “Set” marker lit. Measuring parameters cannot be programmed in measurement. For programming the parameters, cancel the measurement once.

5.5.1 Programming emissivity

If the emissivity of object measured is low, the temperature displayed becomes lower than the actual temperature and the emissivity is to be compensated.

・Press MODE key to get the emissivity programming screen.

Reference

・The default emissivity is 1.00.

・ If you know the emissivity of object measured, program to its value.

If the emissivity is unknown, measure the temperature of object by a thermocouple

or other sensors and program the emissivity to display the same temperature. The reference table of emissivity is shown in [13. Emissivity table]

5.5.2 Programming signal modulation mode

The maximum value, average value, and minimum value can be extracted continuously from the measurement signal (real signal).

13. Emissivity table

The emissivity are values determined by the material of object, profile of its surface, surface roughness, oxidized or not, measuring temperature, measuring wavelength and other factors. They are represented by the thermal radiation ratio "ε" when a black body furnace at the same temperature is measured in the same wavelength band.

The emissivity "ε" is generally known by a value at the wavelength of 0.65µm when an optical pyrometer is used. The emissivity changes according to the above factors even in case of the same material. Please use the following table as a reference.
