Frequently Asked Questions - 42510 Extech

How do I turn on the Extech 42510 thermometer?

Pull and hold the orange Trigger to turn the meter on and begin testing. The display will show temperature, 'SCAN' icon, emissivity, and units.

How do I activate the laser pointer?

While pulling the Trigger, press the laser button (⚙) to turn on the laser. A laser icon will appear on the LCD. Press again to turn off. Do not point at eyes.

What is the measurement range of this thermometer?

The temperature range is -50 to 538°C (-58 to 1000°F).

What is the accuracy specification?

Accuracy is ±1% of reading or ±1°C (±1.8°F) whichever greater for ambient 15-50°C; otherwise ±2% of reading or ±2°C (±4°F).

What does the field of view (8:1) mean?

It means the distance to spot ratio is 8:1. For example, at 16 inches from the target, the measured spot diameter is about 2 inches. Measure within 2 feet for best results.

How do I change temperature units between °C and °F?

While pulling the Trigger, press the °C or °F button to toggle between Celsius and Fahrenheit.

How long does the reading hold after releasing the trigger?

The reading holds for approximately 6 seconds (displays 'HOLD'), then the meter automatically shuts off.

What happens if I measure a temperature above the range?

The display shows dashes instead of a temperature reading when the measurement exceeds 538°C (1000°F).

How do I replace the battery?

When the low battery symbol appears, open the battery compartment by pulling down the light green panel around the trigger. Replace with a 9V battery and close the compartment.

Are there any safety precautions I should know?

Do not point the laser beam at anyone's eye or from reflective surfaces; avoid use near explosive gases; and dispose of batteries according to local regulations.

USER MANUAL 42510 Extech

Wide Range Mini InfraRed Thermometer with Laser Pointer

MODEL 42510

CE

Congratulations on your purchase of the Model 42510 IR Thermometer. This thermometer measures and displays non-contact (infrared) temperature readings at the touch of a button. The built-in laser pointer increases target accuracy while the backlit LCD and handy push-buttons combine for convenient, ergonomic operation. Proper use and care of this meter will provide years of reliable service.

Safety

• Use extreme caution when the laser pointer beam is on
• Do not point the beam toward anyone's eye or allow the beam to strike the eye from a reflective surface
• Do not use the laser near explosive gases or in other potentially explosive areas

Operating Instructions

1. Hold the meter by its Handle Grip and point it toward the surface to be measured.
2. Pull and hold the orange Trigger to turn the meter on and begin testing. The temperature reading, the 'SCAN' icon, the emissivity icon (E=0.95), and the unit of measure will appear. Note: Replace the battery if the display does not light.
3. While continuing to pull the Trigger:

a. Push the laser button ⚙ to turn on the laser pointer. When the laser is ON the laser icon will appear on the LCD over the temperature reading. Aim the red beam approximately a half inch above the point of test (pressing the laser button again turns the laser off).
b. Select the temperature units using the °C or °F button.
c. Push the backlight button ⚙ to turn on the LCD backlighting function.

1. Release the Trigger and the reading will hold for approximately 6 seconds (HOLD will appear on the LCD) and then the meter will automatically shut off.

Over-range Indicator

If the temperature measurement exceeds 538^ (1000°F), the thermometer will display dashes in place of a temperature reading.

Field of View

The meter's field of view is 8:1. For example, if the meter is 16 inches from the target (spot), the diameter of the target must be at least 2 inches. Other distance ratios are shown below in the field of view diagram.

Note that measurements should normally be made less than 2 feet from the target. The meter can measure from further distances but the measurement may be affected by external sources of light. In addition, the spot size may be so large that it encompasses surface areas not intended to be measured.

Measurement Notes

1. The object under test should be larger than the spot (target) size calculated by the field of view diagram.
2. If the surface of the object under test is covered with frost, oil, grime, etc., clean before taking measurements.
3. If an object's surface is highly reflective, apply masking tape or flat black paint to the surface before measuring.
4. The meter may not make accurate measurements through transparent surfaces such as glass.
5. Steam, dust, smoke, etc. can obscure measurements.
6. The meter compensates for deviations in ambient temperature. It can, however, take up to 30 minutes for the meter to adjust to extremely wide ambient temperature changes.
7. To find a hot spot, aim the meter outside the area of interest then scan across (in an up and down motion) until the hot spot is located.

Battery Replacement

When the low battery symbol appears on the lower left side of the display, replace the meter's battery (9V). The battery compartment is located behind the light green panel that surrounds the meter's trigger (see diagram). Open the compartment by pulling the light green panel down from the trigger area. Replace the 9V battery and close the battery compartment cover.
