Introduction
Thank you for purchasing the HIOKI
“Model 3419-20 INFRARED THERMO HiTESTER.” To obtain maximum
performance from the instrument,
please read this manual first, and
keep it handy for future reference.
1. Open the battery cover and take out the battery.
2. Change the battery, while being sure to put them in the right way
round.
3. Put the battery in the case and close the battery cover.
Battery cover
The Model 3419-20 is a no n-c ont a ct therm om ete r us ing inf r ared ray s.
It can measure the surface temperature of an object by measuring the
energy level of the infrared rays emitted from the object without touching it.
• Liquid crystal display with backlight
• Laser marker beam s
• Thermal emissivity setting function
• Display and sound alarm functions
• Measurement va l ue saving funct i on
Inspection and Maintenance
Initial Inspection
When you receive the instrument, inspect it carefully to ensure that no
damage occurred d uring shi pping. In p articu lar, check the a ccessories ,
the liquid cryst al display , the cont rol keys, and the len s. If damage is ev -
ident, or if it fails to o perate according to the specification s, contact your
dealer or Hioki representative.
Maintenance and Service
• To clean the instrum ent, wipe it gently with a soft cloth moistened w ith
water or mild detergen t. Never use solve nts such as benzene, alco hol,
acetone, ether, ketones, thinners or g asoline, as they can deform and
discolor the case.
• If the instrument seems to be malfunctioning, confirm that the battery are
not discharged before contacting your dealer or Hioki representative.
• Pack the instrume nt so that it will not sustain da mage during shippin g,
and include a description of existing damage. We do not take any
responsibility for damage incurred during shipping.

Preliminary Checks
Before using the instrum ent the first time, v erify that it ope rates normally to ensure that the no damage occurred during storage or shipping.
If you find any damage, contact your dealer or Hioki representative.
Do not allow the laser light beam to impinge upon any
gas which can explode.
• Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
• The Model 3419-20 us es as a light s ource a s emicon ductor laser
which emits visi ble light, and which con forms to IEC sta ndard clas s
2 (IEC 60825-1). (Wavelength 650nm, maximum power output 1 mW)
Since there is considerable danger of this laser light causing damage to the eyes, be very ca reful not to dir ect this laser ligh t into your
eyes or those of another person.
• Do not look directly into the laser light from the optical system.
• When measuring the temperature of an object which has a mirror
finish, be careful not t o allo w the las er ligh t beam to be re flected off
the surface into your eyes or those of another person.
• This instrument should be installed and operated indoors only, between 0 and 50°C and 80% RH or less.
• Do not store o r u se th e i ns trum en t w h ere it c oul d be exposed to direct sunlight, high tempe rature or hu midity, or co ndensatio n. Under
such conditions, the instrument may be damaged and insulation
may deteriorate so that it no longer meets specifications.
• This instrument is not designed to be entirely water- or dust-proof.
Do not use it in an especially dusty envi ronment, no r where it might
be splashed with liquid. This may cause damage.
• Do not use t he ins tru me nt w h ere it ma y be exposed to corrosive or
combustible gases. The instrument may be damaged.
• Do not use the inst rum ent near a source of strong el ec trom ag neti c
radiation, or near a highly electrically charged object. These may
cause a malfunction.
• To avoid damage to the instrument, protect it from physical shock
when transporting and handling. Be especially careful to avoid
physical shock from dropping.
• Do not point the lens at the sun or at any other source of strong
light. If you do, the sensor may be damaged.
• Do not contact the lens against the object whose temperature is to
be measured, or get it dirty, allow it to be scratched, or allow any
foreign material to adhere to it. Doing so may cause errors.

marker to enter the eyes and is extremely dangerous.
After exchanging the battery, be sure to close the cover
before using the instrument.
• Be sure to insert them with t he correct polarity. Otherwise, poor performance or damage from battery leakage could result. Replace battery only with the
specified type.
• Battery may explode if mistreated. Do not short- circuit,
recharge, disassemble or dispose of in fire.
• Handle and dispose of battery in accordance with local
regulations.
Take care not to get the cabl e caugh t in th e battery cov er as thi s may
break it.

Measurement
Whenever the indication is blinking, the laser marker beam
is being emitted. Exercise extreme care not to allow the laser
marker beam to enter your eyes or those of another person.
Because of this laser light causing damage to the eyes.
• The center of the mea surement range and the po ints indicated by the
laser markers are off by 18 mm .
• The object whos e temperature is to be meas ured needs to be larger
than the measurement diameter by an adequate margin.
• Consecutive m easurements are carried out by pulling and hold ing the
measuring trigger key. Measurement will stop when the measuring
trigger key is released and the last shown value will be retained.
• The instrument will automatically switch off approximately 15 seconds
after the measuring trigger key is released.

MAX/MIN Measurement
• When the MODE key is pressed on ce during m easurement , “MAX” will
be shown on th e display and the maximum value achieved since the
start of the measurement will be shown.
• When the MODE key is pressed once after MAX is displayed, “MIN” will
be shown on the display and the minimum value achieved since the
start of the measurement will be shown.
• When the MODE key is pressed once after MIN is displayed, the current
value will be shown. The MAX/MIN values will be retained until the
instrument is switched off.
(The MAX/MIN values will be reset when the power is turned off)
Thermal Emissivity
This instrument allows thermal emissivity to be adjusted within the range of 0.17
to 1.00.
Please refer to the following table when setting the thermal emissivity.
Setting the Functions
• Pull the measuring trigger key to switch on th e power.
• When the MODE key is pr essed and he ld for 2 se cond s or mor e, “SET”
will be shown on the display and the SET mode will be activated.
• Each press of the key changes the setting as fo llows:
ON/OFF alarm setting
value setting for th e alarm
ON/OFF alarm setting .....
• When the setting is completed, pull the measuring trigge r key to return
to the Measuring mode.
• Refer to the Measurement section on how to carry out the various settings.
• Settings are retained even after th e pow er is switched off.
• Backlight function and me mory retrieval function are not availab le in t he

The auto power off time for memor y r et riev al is appr oximately 3 minutes.
Pulling the measuring trigger key and pressing the key at the same time
when the instrument is not switched on will cause “CLr” to appear on the display
and all data to be deleted.
• Variations in the surface condition and color of the object whose temp er ature is to be measured may cause the thermal emissivity ε to be somewhat different from the values in the above table. If an accurate
temperature measu rement is des ired for an obje ct whose the rmal emissivity is not known, black bod y tape (sold separa tely) should be used. In
this case the setting for thermal emissivity (ε) should be the value indicated on black body tape.
• Iron and other objects with low thermal emissivit y reflect their surround ing temperature, causing inaccuracies in measurement. The black body
tape (sold separately) are also recommended when measuring these
objects of low thermal emissivity.
