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.
9
familiarise yourself with the applications, limitations, and potential hazards of the thermometer.
9
Keep the thermometer clean and in good condition.
9
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.
8
do not
get the thermometer wet or use in damp or wet locations or areas where there is condensation.
8
do not
take readings through transparent materials such as glass or clear plastic. the surface temperature of these materials will be
measured.
8
do not
use the thermometer in areas where there is steam, dust or smoke. these conditons will result in erroneous readings.
8
do not
use the thermometer
for any purpose other than that for which it is designed.
8
do not
allow untrained persons (particularly children) to operate the thermometer.
8
do not
operate the thermometer
when you are tired or under the influence of alcohol, drugs or intoxicating medication.
1.1.
laser safety
the Vs940 and Vs941 utilise 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.

introduction
detects energy in the infrared spectrum and displays the temperature on an 18mm lcd back-lit display. twin spot laser targeting enables
accurate readings by guiding user to the unit’s optimum guiding distance - when the two laser dots merge into one, unit is reading a 13mm disc
of temperature. features data hold and auto power off. temperature can be shown in either °c or °f. Powered by 9V battery (supplied).
