INFRARED SENSOR MEASUREMENT
Switch on the instrument and be sure
that it is in the IR (infrared) mode.
Note: If a “P” appears on the LCD, it means that the
thermometer is in the external probe mode. Press the
IR/CONTACT button to switch to IR (infrared) measurement mode.
To obtain the temperature
of an object, simply aim
the sensor in the direction
of the object.
Reading Distance
The distance between the sensor and the object is an
important factor in infrared measurement.
The relation between “distance/object area” is 3:1. This
means that the diameter of the measured area is one third
of the distance between the sensor and the object.
EMISSIVITY
The instrument measures the temperature of objects contain-
ing an emissivity of 0.95, which is the characteristic of most
substances, such as, organic material, water, plastic, fabrics,
etc.
To measure substances that have a polished surface and are
very reflective, the emissivity needs to be compensated. It is
advisable to cover the object with black paint or black
adhesive tape to compensate for the reflectivity.
WARNING
To avoid damage, do not hold the sensor too close to a
heat source for a long period.
SENSOR CLEANING
To maintain the instrument’s accuracy, it is important that
the sensor lens is kept clean. To clean the sensor, gently pass
a humid and non-abrasive cloth (HI 731318) on the lens.
EXTERNAL PROBE
Connect the temperature probe
HI 765PWL to the connector
on top of the instrument.

WEAK BATTERY
HI 99556HI 99556
HI 99556 continuously checks the battery status. If the
HI 99556HI 99556
battery level is too low to guarantee the stated accuracy, it
shuts off the LCD completely. If the meter cannot be switch
on, or switches itself off after being switched on, replace the
battery.

Battery replacement must only take place in a non-hazardous area using a 9V alkaline battery.
Simply slide off the battery cover on the back of the meter.
Detach the battery from the terminals and attach a fresh
9V battery while paying attention to the correct polarity.
Replace the battery and the cover.

Recommendations for Users
Before using these products, make sure that they are entirely suitable for the environment in which they are used.
Operation of these instruments in residential area could cause unacceptable interference
to radio and TV equipment, requiring the operator to take all necessary steps to correct
interferences.
Any variation introduced by the user to the supplied equipment may degrade the
instruments' EMC performance.
To avoid damage or burns, do not perform any measurement in microwave ovens.
For example, if the sensor is 15 cm away from the object,
the instrument measures the temperature of an area with a
5cm diameter.
Dip the probe in the substance which you intend to measure
(4cm immersion level is recommended) and wait for the
reading to stabilize.

GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
Infrared radiation emitted from any object depends on its
temperature. HI 99556 is a thermometer based on the
infrared radiation technology.
The most evident advantage of infrared thermometry is the
non-contact nature of the measurement.
HI 99556 also accepts an external thermistor temperature
probe. The selection of measurement between the external
probe and infrared sensor is simply through a key.
The different models are:
HI 99556-00 measures in Celsius,
HI 99556-01 measures in Fahrenheit,
HI 99556-10 measures in Celsius.
The thermometers also provide for a low battery indication.
