INSTRUMENT OPERATION

 - Insert and connect the battery provided into the battery 

compartment, this compartment is located in the handle. To use, aim the Mini RayTemp 
Infrared thermometer at the target and press the trigger to measure the surface 
temperature, 'SCAN' will be shown on the display, then the trigger is released 'HOLD' is 
shown and the reading is held for 10 seconds, after which the thermometer will shut down.

  

Please note:

 Holding the trigger down for a long period of time could affect the reading 

shown in the display.

MEASUREMENT ZONE/TARGET DISTANCE

 - The measurement zone is proportional to 

the distance the infrared thermometer is away from the target. The Mini RayTemp is 
equipped with a 12:1 lens. If the target is 60 cm (24") away, the measurement zone will 
be 5 cm (2") across.

EMISSIVITY

 

- The Mini RayTemp has a fixed emissivity of 0.95. 

Please note: 

non-contact 

infrared thermometers are not recommended for use in measuring shiny or polished 
metals.

LASER POINTER

 - The laser pointer function cannot be turned off. The centre of the 

measurement zone is 16 mm (approximately ¾") below the laser dot with the instrument 
held in a vertical position. For safety, the laser pointer will only activate when the trigger 
button is pressed. The laser module is a Class 2 device that has a maximum power 
output of less than 1 mW at a wavelength of 630 to 670 nm. Prolonged, continuous 
exposure such as staring at the beam can be harmful and should be avoided. DO NOT 
look into the beam of any optical instrument.

UNDER RANGE/OVER RANGE

 - If the measured temperature goes below or above the 

range of the instrument, 'Lo' or 'Hi' will be displayed. When the measured temperature 
returns within the range of the instrument, readings will automatically be displayed.

BATTERIES

 

- The low battery icon indicates that the battery needs replacing as soon as 

possible. The instrument will continue to function but, to maintain accuracy, a new battery 
is required. Replace with one 9V PP3 battery.

CARE

 - The sensor lens is the most delicate part of the Mini RayTemp. Do not insert any 

foreign bodies into the sensor aperture as this will cause damage to this lens. Do not 
submerge any part of the unit. The instrument should be stored at room temperature 
between 10 and 40 °C.
