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 beam 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 tachometer.
9
Keep the tachometer clean and in good condition.
9
Protect the tachometer from electro-magnetic fields, static electricity and high temperatures.
9
remain vigilant when using the tachometer on, or near, a running engine where there are rotational parts such as belts, pulleys and fans.
9
maintain correct balance and footing. ensure the floor is not slippery and wear non-slip shoes.
9
remove ill fitting clothing. remove ties, watches, rings, and other loose jewellery, and contain and/or tie back long hair.
9
do not wear gloves near rotational parts.
8
do not get the tachometer wet or use in damp or wet locations or areas where there is condensation.
8
do not use the tachometer for any purpose other than for which it is designed.
8
do not allow untrained persons (particularly children) to operate the tachometer.
8
do not operate the tachometer when you are tired or under the influence of alcohol, drugs or intoxicating medication.

1.2. laSer SaFetY
the tA050 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.
8
do not operate the tachometer 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.

2. introduction
i
Professional quality laser instrument for fast and accurate measurement of rotational speed with or without contact. Will also measure total
revolutions, frequency, surface speed and distance. ten selectable data set memories each with maximum, minimum, and average or single
value reading as appropriate. supplied with reflective tape, for non-contact measurement, and three heads for contact measurement. Powered
by 9V battery (supplied) and has jack socket for 6V dc supply.
