2. INTRODUCTION & SPECIFICATION
Fast and simple way to tackle diagnosis of engine and vehicle faults. VS904 detects energy emission in the infrared spectrum and
converts reading into a display of temperature. Features laser pointer to indicate area being sampled. Temperature is displayed on a
large LCD panel. Temperature can be shown in either °C or °F. Powered by 2 x AAA batteries (not included).

1.2 LASER SAFETY.
The VS904 utilises a Class II laser that emits low levels of visible radiation (i.e. wavelengths between 400 and
700 nanometres) which are safe for the skin but not inherently safe for the eyes. The Class II emission limit is
set at the maximum level for which eye protection is normally afforded by natural aversion responses to bright
light. Accidental eye exposure is therefore normally safe, although the natural aversion response can be
overridden by deliberately staring into the beam, and can also be influenced by the use of alcohol or drugs.
!WARNING! Do not look or stare into the laser beam as permanent eye damage could result.
$DO NOT direct the laser beam at any person’s (or animal’s) eyes as eye damage could result.
#DO NOT operate the thermometer when you are tired or under the influence of alcohol, drugs or intoxicating medication.
"Be aware that reflections of the laser beam from mirrors or other shiny surfaces can be as hazardous as direct eye exposure.

4.3 For all other errors, a generic error message “Er” is displayed. In the event of this
occurring, it will be necessary to reset the unit. To reset the unit, turn the
instrument off, remove the battery and wait at least one minute. Now reinsert the
battery and turn the unit on. Should the error message remain, contact your
authorised Sealey dealer for assistance.
5. BATTERIES
5.1 The VS904 incorporates a visual guide to the battery status:
“Battery OK”
Measurements are possible.
“Battery Low”
Battery needs replacing.
Measurements are possible.
“Battery Exhausted”
Measurements are not possible.
Replace battery.
5.2 When the “Battery Low” symbol appears, the batteries should be replaced immediately with two batteries which are
located under the cover on the front of the handle grip.
NOTE: It is important that the unit is off before the batteries are replaced. A malfunction could occur if this precaution
is not taken. Be sure to dispose of the batteries safely and in accordance with local laws regarding potentially hazardous
waste.
4. LCD ERROR MESSAGES
4.1 “Hi” or “Lo” will be displayed when the temperature being measured is outside the
range of the instrument. (See Specification, section 2.)
4.2 “Er2” is displayed when the unit is exposed to rapid changes in ambient
temperature.
“Er3” is displayed when the ambient temperature of the unit is below 0ºC (32°F)
or exceeds 50ºC (122°F). In both cases allow a minimum of 30mins for the unit to
stabilise and adapt to the working temperature.
6. STORAGE AND CLEANING
6.1 The sensor lens should be kept clean at all times. Care should be taken when cleaning the lens - it is an extremely
delicate piece of equipment. Use a cotton swab moistened with a little water or medical alcohol, allowing the lens to dry
fully before attempting to use the unit.
DO NOT submerge any part of the VS904.
6.2 The VS904 should be stored between -20ºC and +65ºC.

3. OPERATION
3.1 To measure the surface temperature of an object/region, simply point the device at the object/region in question and press the
trigger.
NOTE! When the trigger is released the reading will be held for 15 seconds (HOLD will be displayed) and then the thermometer will
automatically shut down unless the trigger is pressed again.
3.2 ºC/ºF MODE.
3.2.1 To change the display from ºC to ºF (or visa versa), firstly turn the unit on by pressing the trigger. Now press the mode
button and the ºC or ºF symbol will be displayed, press again to cycle display between ºC or ºF.

Environmental Protection.
Recycle unwanted materials instead of disposing of them as waste. All tools, accessories and packaging should be sorted,
taken to a recycle centre and disposed of in a manner which is compatible with the environment.
When the product is no longer required, it must be disposed of in an environmentally protective way. Be sure to dispose of
the batteries safely and in accordance with local laws regarding potentially hazardous waste.
2.3 Emissivity
2.3.1 Emissivity is a term used for the ability of a surface to radiate energy. Most (90% of typical applications) organic materials and
painted or oxidised surfaces have an emissivity of 0.95 (pre-set in the thermometer).
2.3.2 Inaccurate readings will result from measuring shiny or polished surfaces. To compensate, cover the surface to be measured
with masking tape or flat black paint.
2.3.3 Allow time for the tape to reach the same temperature as the material underneath it. Measure the temperature of the tape or
painted surface.
