INTRODUCTION The RS 1327K hand-held thermometer is a convenient and easy to use instrument, allowing temperature measurement either by an Infrared non-contact method, or by using a plug-in type-K thermocouple probe. The thermometer has an integral laser to assist sighting the...
Ⅰ. SAFETY INFORMATION 1. Read the following safety information carefully before attempting to operate or service the meter. Laser Safety Warning LASER RADIATION DO EN 60825-1:1994/A11:1996 If the button is pressed while the symbol is shown MEAS on the LCD, the meter will radiate the laser. To prevent injury, do not look or stare into the beam.

Ⅶ. TEMPERATURE MEASUREMENT 1. Non-contact measurement : Point the instrument at the target and pull the trigger to turn it on and start measuring (use the laser to select the target if required). Release the trigger to stop measuring and auto-hold the reading. The meter will turn off automatically after 15 seconds.

Note: Laser offset: The laser beam is offset 18mm(0.71in) from the focal lens. Choose a sampling spot that is large enough to include the laser offset. Surface Temperature: The thermometer will measure the temperature of the first surface it detects, e.g. a glass cover, dust or fog.
Reading the memory data: Press and hold the R button for 3 seconds to enter READ mode. Press the ▲ or ▼ buttons to select to desired memory data location. Press the MODE button to exit READ mode. Ⅷ. SETTING MODE Pull trigger to turn the meter on.

Setting procedure: a). Press and hold the key for 3 seconds until the MODE LCD displays the “SET” mark. b). Press “▲” button to select °C unit. c). Press the button once to enter ALARM ON/OFF MODE setting mode, then press the ▲ or ▼ key to select “ON” mode.
Ⅸ. BATTERY REPLACEMENT When the symbol appears on the LCD screen, there is insufficient power in the battery to provide an accurate measurement. Replace the battery with a fresh one as follows: a) Ensure the instrument is turned off b) Open battery compartment cover on the rear of the grip. c) Remove the exhausted battery from the compartment.
