Tenmars TM-300 User manual

TENMAR.S
Compact rugged and easy to use. Just aim and push
the button, read current surface temperatures in less
than a second. Safely measure surface temperatures
of hot or hard to reach objects.
Any object radiates infrared energy if its temperature
is above absolute zero.This energy travels at the speed
of light in all directions. An infrared thermometer lens
collecls and focuses the infrared energy onto a sensor.
The sensor produces a small voltage output, proportional
to the target temperature, which is processed and
displayed.
The infrared thermometer should be protected from
the following:
O Electro Magnetic Fields (created by arc welders,
induction heaters and similar items.)
O Thermal Shock (caused by large or abrupt ambient
temperature changes. Allow 30 minutes for unit to
stabilize before use.)
a Do not leave the unit on or near objects of high
temperature.

1) Pull and hold trigger (laser pointer is on as default
setting) to turn on, LCD display reading & battery
icon. Release the trigger and the reading will hold
forapprox. l5secs.
2) Locating a hot spot: Aim the thermometer outside
the area of interest. Scan across lhe area in an up
and down motion until the hot spot is located while
holding the activation trigger. The thermometer will
continue to read the surface temperature while the
activation trigger is depressed.
Note
Holding the trigger should last about 1 second at least
Fahrenheit & Celsius Conversion: Press the "F/"c
button to switch from Fahrenheit to Celsius readings.
Press the Laser ON/OFF button to turn the laser
pointer on or off.
The object being tested should be larger than the spot
size calculated by the field of view diagram printed in
this manual or on the unit itself

The farther the thermometer is from the target, the larger
the target area will be. This relationship betvveen distance
and target size is normally expressed as the distance
to spot, or D:S ratio, At a distance of 8 feet, the "target"
spot would be 1 foot in diameter. The thermometer will
display the average temperature across the target area.
3" @24"
Distance to Spot size: 8: 1
Most organic materials and painted or oxidized
surfaces have an emissivity of 0.95.This unit is preset
at 0.95.lnaccurate readings will result from
measuring shiny or polished metal suraces.To
compensate,cover the surface to be measured with
masking tape or flat black paint.Measure the tape or
painted surface when the area has reached the same
temperature as the material underneath.
To clean the lens : Blow off loose particles using clean
compressed air. Gently brush remaining debris away
with a moist cotton cloth.
Do not use solvents to clean the lens.
Do nol submerge the unit under water.

Be sure to consider distance to spot size ratio
and field of view when using this unit.
Always wear eye protection when using tool
Do not operate the thermometer around
explosive gas, vapor, or dust.
