Model 914 604-
Infra-red thermometer
Congratulations on your purchase of the Infrared
Thermometer! One-click for a temperature reading.
No surface contact required, prevents contamination.
Take a Measurement:
Place the thermometer close to the item to measure.
Click the button once to measure the surface temperature. The
reading will display for 15 seconds.
Hold the button for ongoing readings.
Auto Shut Off:
When the button has not been pressed for 15 seconds, the
thermometer will automatically shut off to save power.
Note: When measuring temperatures above 199.9 °F the last
number will be smaller, due to LCD size. Example: 205 °F will
show as 20 . 5
Applications:
Check doors and windows for drafts.
Maintain proper cooking, cooling and holding
temperatures.
Measure food or liquid temperature (no contact, thus no
contamination)
Measure oven, stove & grill temperatures up to 390.2 °F.
Check heating & cooling ducts, in-floor heating and
furnace temperatures.
Measure engine exhaust, tires and hard to reach areas
Description of measuring principle
When making a temperature measurement, the surface
radiation of the object measured is evaluated, using the
principle of radiation thermometry. This is a purely passive
process, i.e. no radiation is transmitted, but instead, use made
of the natural electromagnetic radiation energy (heat radiation).
Everything above a temperature of absolute zero (−459.67 °F)
has heat radiation.
D/S Ratio: The distance to target diameter ratio (Distance:
Spot) is 1:1 therefore the device should be positioned as close
to the target as possible. As you move farther from the target,
you will receive ambient temperature around the target.
Measuring Tips:
Not recommended for use in measuring shiny or polished
metal surfaces (stainless steel, aluminum, etc.) The
reading will not be accurate.
It is not possible to take measurements through
transparent materials (glass, Plexiglas, etc.). It will
measure the temperature of the transparent surface
instead.
It is not possible to measure air temperatures.
Measurement errors can occur due to air contaminated
with dust, steam, smoke, etc.
Battery Replacement:
Battery is low and no more measurements are possible.
Replace the battery immediately with a lithium button CR2032
cell.
1- Power off the thermometer before replacing the battery
A malfunction may occur if the power is on during battery
replacement. If a malfunction occurs, restart the device.
2-Twist the battery cover on the back of thermometer to loosen
the cover and remove the old battery. A coin will work well.
3- The new CR2032 battery is installed positive side up.
Take care that the metal contacts at the top of the battery
compartment are not bent.
4-Replace the battery cover and tighten.
Troubleshooting:
Problem Solution
No Display: Press the button
Ensure battery polarity is correct
Change the battery
Display “oFF”: Automatic switch off (15 seconds)
Display “Hi”: Temperature is above 390.2 °F
Display “Lo”: Temperature below -27.4 °F
Caution!
Do not aim too close at hot or dangerous targets.
Keep the thermometer and battery away from children.
Batteries can explode if thrown into fire, short-circuited,
taken apart or recharged.
Battery can be fatal if swallowed. If a battery has been
swallowed, get medical attention immediately.
tteries contain harmful acids. Change low batteries as Ba
soon as possible to prevent damage caused by a leaking
battery.
Wear chemical resistant protective gloves and safety
glasses when changing the battery.
Care and Maintenance:
Do not place the instrument near extreme temperature,
vibration or shock.
Protect the unit from large abrupt temperature changes.
Do not store near objects of high temperature.
Do not immerse the unit in water. Water can penetrate and
cause malfunction. Protect from moisture.
Steam, dust, some can prevent accurate measurement by
obstructing the units optics.
