6. Battery

This device is battery-operated, using 1x 9 V battery. Replace it when the

battery-low icon appears.

To replace the battery, proceed as follows:

1. Wait until the device powers off automatically (about 35 s).

A malfunction may occur if you replace the batteries while the

device is on.

2. Open the battery compartment.

3. Replace the battery with a new 9 V battery.

4. Close the battery compartment.

Warning: Do not puncture batteries or throw them in fire as they

may explode. Do not attempt to recharge non-rechargeable

batteries (alkaline). Dispose of batteries in accordance with local

regulations. Keep batteries away from children.

7. Operation

7.1 Measuring the Temperature

1. Aim the IR sensor at the target and press the measurement trigger to

display the target’s surface temperature. A red laser spot appears on

the target during measurement.

2. The distance-to-target ratio is 30:1. This means that, for example, at

30 cm, the target must be larger than 1 cm to get a proper

measurement. Make sure the target area is within this field of view.

3. The device can measure temperatures in °C or °F. Press the up/down

key while the device is on to switch between measurement units. The

corresponding symbol (°C or °F) appears on the display.

4. Press the laser/backlight button to switch the laser pointer on or off; in

data-hold mode, press the laser/backlight button to switch the

backlight on or off.

5. When you release the measurement trigger, the hold mode is

automatically activated: the last measurement value remains on the

display until you press the measurement key again, or until the device

shuts off automatically (after approx. 35 seconds).

6. Note that the display is always on, while the laser is only on during

measurement.

Remarks: The temperature

of a shiny or polished metal surface

through a transparent surface such as glass

of an object covered with frost, grime, oil

cannot be measured.

7.2 Measuring the Emissivity

1. Hold the setting button pressed to enter/exit the emissivity mode.

2. Adjust the emissivity value with the up/down button.
