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
Infrared sensor for making non-contact measurements of items
that are inaccessible or hazardous to touch such as rotating
machinery, high-voltage bus-bars, or inaccessible objects. The
Infrared mode does not rely on physical contact with the object
whose temperature is to be taken, but measures the radiated
infrared energy from the object.
The thermocouple connector will accept a standard liquid, air or
surface thermocouple probe as required to suit the particular
application.
The Liquid Crystal Display has a backlight function which may
be enabled to assist measurements made in a dark place.
Other features include reading auto-hold, auto power-off,
maximum and minimum readings, alarm levels and adjustable
emissivity, all of which can be selected for maximum operating
convenience.

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 MEAS button is pressed while the symbol is shown
on the LCD, the meter will radiate the laser. To prevent injury,
do not look or stare into the beam. Do not point the laser
directly at eyes or indirectly off reflective surfaces.
●If the target object has a smooth surface, the laser may be
reflected and create a hazard.
●Do not radiate the laser at flammable gasses or other
possible sources of ignition.
2. Precautions:
a). Do not operate the thermometer in the presence of strong
electrical or magnetic fields, as this may prevent correct
operation.
b). Use and store the thermometer away from direct sunlight
or other strong source of light, high temperatures, high
humidity or dust.
c). If the thermometer has been kept in area of high or low
temperature, wait until it has reached a stable temperature
before use.

E-3
d). Condensation may form on the focal lens if the
thermometer is moved quickly from a cold to a hot
environment. Before taking measurements, wait for the
condensation to dissipate.
e). Do not touch the focal lens.
3. Environmental conditions:
a). Altitude up to 2000 meters.
b). Relatively humidity: 80% max.
c). Operating ambient temperature: 0 to 50 °C
4. Maintenance & Clearing:
a). Repairs or servicing should only be carried out by
competent persons using the correct parts, test equipment
and procedures. If repair or servicing is required, contact
the supplier or RS Components. The address is given at
the end of these instructions.
b). Periodically clean the case with a dry cloth. Do not use
abrasives or solvents.
5. Safety symbols:
Complies with the EMC Directive 89/336/EEC
