Use

English

1. Press and hold themeasuring button (4) to
start themeasuring. The display will light
up if thebattery is good (change batteries if
thedisplay does not light up).

2. Hold theIT thermometer in its handle and point
it at thesurface to be measured. The laser point
indicates where on thesurface thetemperature
gets measured. “SCAN” will show in theupper
left corner of thedisplay during measuring.

3. Let go of themeasuring button to finish
themeasuring. The measured temperature and
theword “HOLD” is shown on thedisplay.

4. The IR thermometer is automatically shut off
6 seconds after themeasuring is finished.

Turn thelaser pointer on/off

English

The laser pointer can be turned on or switched off
with theswitch behind thebattery cover.

Set theswitch to ON (laser pointer is shown) or

OFF (laser pointer is off).

Emissivity

Most organic materials (ca 90 %) with apainted
or oxidised surface have anemission ratio of 0.95
(preset on theIR thermometer). Shiny materials
should be masked or painted black before
measuring. Give thetape or paint thetime to reach
thetemperature of themeasuring object. Measure
themasked or painted surface.

Function

The IR thermometer reads thetemperature on
thesurface and measures thereflecting energy
collected in thesensor. The electric device converts
themeasured value to atemperature shown in
thedisplay. The laser beam is only used to direct
themeasuring centre.

Measuring range

Always make sure that thesurface to be measured
is larger than twice themeasuring area of
theinstrument at thecurrent measuring distance.

Distance and measuring range

The measuring area increases with increased
measuring distance (see chapter Measuring range).

Find thehottest surface

Search as usual, but move theIR thermometer
slowly back and forth over thewhole measuring
area and constantly read until you find thehighest
temperature.

14

Note:

• Do not use thethermometer to measure shiny
or polished surfaces e.g. stainless steel (see
chapter Emissivity).

• The IR thermometer can not measure through
glass, it will then read thetemperature of
theglass.

• Steam, dust or smoke can give false readings.

Care and Maintenance

Change of battery

• When thebattery is bad thebattery warning
icon appears.

• Remove thebattery cover (5) and replace
thebattery of type 6LR61 (9 V).

Disposal

Follow local ordinances when disposing of this product.
If you are unsure about how to dispose of this product
