VOLTCRAFT IR-380 - Infrared Thermometer Manual

Intended use

The device serves for non-contact temperature measurement. It determines the temperature by the amount of infrared energy emitted by the object and its emissivity. It is especially useful for temperature measurement of hot, hard to reach or moving targets.

The thermometer measures the surface temperature of an object. It cannot measure through transparent surfaces such as glass and plastic. Its temperature measuring range is from -50ºC to 800ºC. It is powered by a 9V block battery.

This product fulfi ls European and national requirements related to electromagnetic compatibility (EMC). CE conformity has been verifi ed and the relevant statements and documents have been deposited at the manufacturer.

Any usage other than described above is not permitted and can damage the product and lead to associated risks such as short-circuit, fi re, electric shock, etc. Please read the operating instructions thoroughly and keep them for further reference.

Battery installation

Observe correct polarity while inserting the batteries. Remove the batteries if the device is not used for a long period of time to avoid damage through leaking. Leaking or damaged batteries might cause acid burns when contact with skin, therefore use suitable protective gloves to handle corrupted batteries.

Keep batteries out of reach of children. Do not leave the battery lying around, as there is risk, which children or pets could swallow it.

Make sure that batteries are not dismantled, short-circuited or thrown into fi re. Never recharge non-rechargeable batteries. There is a risk of explosion!

Replace the battery when the low battery symbol, , appears.

1. Open the battery compartment (5).
2. Insert one 9V block battery to the battery terminal (8). The 9V block battery is designed to be connected in one orientation only to avoid wrong polarity. Do not insert the battery by force.
3. Close the battery compartment (5).

Operation

1. Point the opening (9) of the thermometer towards the target. For accurate temperature measurement aim the thermometer perpendicular to the target.
   • To measure the temperature of a stationary or fi xed surface, aim the sensor at the starting point and move it across the surface.
   • To take a temperature scan of a moving surface, aim the sensor at a fi xed point and measure the temperature as the target moves past, or continually scan across the target as it moves past.
2. Hold the trigger (6) to initiate the measurement. "SCAN" appears on the display (1).
3. The measured temperature will be shown on the display (1).
4. Upon releasing the trigger (6), the measured value will be held for 7 seconds. "HOLD" appears on the display (1).

The thermometer is switched off after 7 seconds unless the thermometer is locked.

To locate the hot or cold spot

1. Aim the thermometer outside the target.
2. Scan across the target with up and down motion.

The thermometer is not recommended for use in measuring refl ective surfaces such as stainless steel and/or aluminium wrapping. The temperature of a refl ective object may be measured if the surface is coated with a matt material.
The thermometer needs to adjust to the ambient temperature in order to produce correct readings.

Distance to spot ratio (D/S)

The target should be larger than the thermometer's measurement spot size to achieve precise measurement.
The temperature recorded is the average temperature of the spot.
The smaller the target is, the shorter the distance is between the thermometer and the target.

Dual targeting lasers

For determining the measuring area easily, dual targeting lasers for aiming are integrated. The two laser spots converge to a single spot when at a distance of 260 mm from the target. From then onward, they indicate the true diameter of the measurement spot.

For precise measurement, it is recommended to keep the measuring distance at 260 mm whenever possible.

Press the "" button (2) to activate/ deactivate the dual targeting lasers. The "" symbol appears on the display to indicate that the targeting laser is activated.

The lasers are turned on when the trigger is pulled and turned off when the trigger is released.

Measuring unit adjustment (ºC/ ºF)

Locate the "ºC/ ºF" slide switch (7) inside the battery compartment. Set the switch position to "ºC" or "ºF" to set the measuring unit.

Backlight

Press "" button (3) to activate the display backlight when measuring in dark environment.

Field verifi cation of accuracy

The thermometer is calibrated, but its accuracy can be verifi ed in the fi eld by using the following procedure.

1. Prepare an aluminium container such as beverage can.
2. Paint the container with matt black spray paint or apply matt black adhesive material to the outer surface.
3. Fill the aluminium container with refrigerated water, insert a standard thermometer and allow the can and standard thermometer to come to equilibrium.
4. Take a reading with the thermometer. Do not exceed the spot size of the IR thermometer.
5. Compare the temperature reading of the IR thermometer with the standard thermometer.
6. Repeat this procedure using hot water.

Configuration

1. Press the "MODE" button (4) to advance through the selection sequence as shown in above diagram.
2. Press the " " button (2) or " " button (3) to adjust the value of the selected setting.
3. Press the trigger to save the adjustment and exit the configuration mode.

Emissivity (EMS) adjustment

The emissivity depends on the material and its surface characteristics. Most organic materials or oxidized surfaces have an emissivity of approx. 0.95, which is the default value of this thermometer. However, metallic surfaces or shiny objects have a lower emissivity. To compensate this, the thermometer integrates an emissivity adjustment function for accurate measurement.

1. Press the "MODE" button (4) until the " =" symbol fl ashes to select emissivity adjustment.
2. Press the "" button (2) or "" button (3) to adjust the emissivity, from 0.10 to 0.99. For reference emissivity value, please refer to "Surface emissivity" table in the "Technical data".
3. Pull the trigger to save the adjustment and exit the configuration mode or press the "MODE" button (4) to advance to the next setting.

Lock on/off (LOCK)

The lock feature sets the thermometer to continuous measurement.

1. Press the "MODE" button (4) until the "" symbol fl ashes to select lock function.
2. Press the "" button (2) or "" button (3) to turn on/off the lock function. ("ON" = on; "OFF" = off)
3. Pull the trigger to save the adjustment and exit the configuration mode or press the "MODE" button (4) to advance to the next setting.
4. When the lock is on, the "" symbol appears. The thermometer will measure continuously without the trigger being held.
5. Pull the trigger to turn off the lock function.

High Alarm (HAL)

1. Press the "MODE" button (4) until the " " symbol flashes to select the high alarm function.
2. Press the "" button (2) or "" button (3) to turn on/off the high alarm function. ("ON" = on; "OFF" = off)
3. Press the "MODE" button (4) to proceed to set the alarm value.
4. Press the " " button (2) to increase or "" button (3) to decrease the alarm value within the range of -50.0ºC to 800.0ºC.
5. Pull the trigger to save the adjustment and exit the configuration mode or "MODE" button (4) to advance to the next setting.
6. The " " symbol appears to indicate that the high alarm is activated.
   An audible alarm will be generated if the measured value is above the temperature set in the high alarm (HAL).

Low Alarm (LAL)

1. Press the "MODE" button (4) until the " " symbol fl ashes to select the low alarm function.
2. Press the "" button (2) or "" button (3) to turn on/off the low alarm function. ("ON" = on; "OFF" = off)
3. Press the "MODE" button (4) to proceed to set the alarm value.
4. Press the "" button (2) to increase or "" button (3) to decrease the alarm value within the range of -50.0ºC to 800.0ºC.
5. Pull the trigger to save the adjustment and exit the configuration mode or "MODE" button (4) to advance to the next setting.
6. The " " symbol appears to indicate that the low alarm is activated.
   An audible alarm will be generated if the measured value is below the temperature set in the high alarm (LAL).
