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).
