1. SAFETY INSTRUCTIONS
1.1. General Safety
WARNING! Ensure that Health & Safety, local authority and general workshop practice regulations

are adhered to when using this equipment.
WARNING! DO NOT aim the laser beams at your or another person's or animal's eye and beware of

reflections from mirrors or other shiny surfaces.
Familiarise yourself with the applications, limitations, and potential hazards of the thermometer.

Keep the thermometer clean and in good condition.

Protect the thermometer from the following:

Electro-magnetic fields from engine components, arc welders and induction heaters closer than 125mm.
Static electricity.
Thermal shock caused by large and/or rapid ambient temperature change.
High temperatures.
DO NOT get the thermometer wet or use in damp or wet locations or areas where there is condensation.

DO NOT take readings through transparent materials such as glass or clear plastic. The surface

temperature of these materials will be measured.
DO NOT use the thermometer in areas where there is steam, dust or smoke. These conditons will

result in erroneous readings.
DO NOT use the thermometer for any purpose other than that for which it is designed.

DO NOT allow untrained persons (particularly children) to operate the thermometer.

DO NOT operate the thermometer when you are tired or under the influence of alcohol, drugs or

intoxicating medication.
1.2. Laser Safety
The VS904.V2 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.

Be aware that reflections of the laser beam from mirrors or other shiny surfaces can be as hazardous as direct eye exposure.

2. INTRODUCTION/SPECIFICATION
2.1. Introduction
High resolution laser thermometer that detects energy emission in the infrared spectrum and converts reading into a display of temperature.
Features laser pointer, data hold function and auto power off. Temperature is displayed on a large 23mm LCD panel with back-lit display for
use in low light areas. Temperature can be shown in either °C or °F. The Digital Thermometer is powered by a 9V cell (supplied).
