Infrared Thermometer
The MS6530
The MS6530 is a type of high precision temperature measuring device
know as an Infrared Non Contact Thermometer. There are many
situations where contact with the object is undesirable, should be avoided
or is simply not possible. For example, where surfaces are hazardous or
are moving, where hygiene is an issue, where things are dangerous or
inaccessible, in continuous industrial processes, and so on.

Infrared Thermometer
Operating principle
All surfaces emit thermal radiation. The type and amount of this energy
can be used to determine the surface temperature of the object.
The MS6530 detects radiation at infrared frequencies, in a narrow band
from 8 to 14 micrometres, and focusses it onto a sensor. An internal
microprocessor calculates and displays the temperature on an LCD
screen.
The laser is used only to indicate the target area to be measured. Laser
light has no effect upon the measured temperature.
Inserting and Changing the Battery
The unit requires a 9 Volt battery, type 6LR61.
Perform the following procedure when you
first receive the unit or when the battery low
indicator shows (16).
Pinch the PEN characters on the unit
handle (7), just below the trigger (6).
The battery compartment hinges from the
bottom of the handle.
Clip the battery connector onto the top of
the battery. Make sure that the battery
polarity is correct. Connecting the battery
the wrong way round may damage the
unit.
Press the battery into the handle.
Position the battery cables inside the compartment.
Clip the battery cover (7) back into place.

Infrared Thermometer
Measuring Temperatures
Point the unit at the object to be measured. If desired you may press the
laser button (2) to indicate the target area.
Press and release the trigger (6).
The temperature (14) of the object appears on the LCD screen.
The LCD screen will hold the temperature for 7 seconds, indicated by the
H symbol (13).
If you need to measure temperature continuously just press and hold the
trigger (6). The Scan indicator (18) on the LCD screen stays on.
If require you can light up the screen up using the back light button (4).
Switching the Mode
The LCD screen has a twin temperature display. The central reading
shows the current value in large digits (14). The M DE button allows you
to change the reading of the second, calculated value.
Press the M DE button (3) to cycle through the options, Average (AVG),
Maximum (MAX), Minimum (MIN), and difference between Maximum and
Minimum (MAX-MIN).
Obtaining Accurate Measurements
To obtain accurate and repeatable measurements you need to consider a
range of variables. Most important are the D:S ratio and Emissivity. If you
do not pay attention to these your readings may be inaccurate.
D:S Ratio
Pressing the laser button (2) shows a ring of 12 laser spots and one
central point. The Laser indicator (12) on the LCD screen stays on.
As the distance (D) from the measured object increases so does the spot

size (S). The ratio between these values is fixed at 12:1. For example at
1metre the spot size is 84millimetres wide, at 1.5 metres the spot size is
125millimetres.
For accurate readings the target should be larger than the visual spot size
and should fill the field of view as indicated by the laser dots.
For small targets you may have to be quite close.
Emissivity
Emissivity is a crucial part of obtaining accurate and repeatable readings.
Emissivity is a complex and difficult area. bjects made of different
materials and with different surface finishes will have different emissivities.
Emissivity also varies with frequency, some objects are transparent to
certain frequencies but opaque to others.
In the case of the MS6530 the emissivity is fixed at 0.95. Most organic
materials and metal surfaces range between 0.85 and 0.98. 1.0 would
be a theoretically perfect object, reflecting all the energy that fell on it.
The result is that if the emissivity of an object measured with the MS6530
is less than 0.95 the reading will also be less than the true temperature of
the object. If the emissivity is more than 0.95 the reading will be higher
than the true temperature.
Note that shiny or polished surfaces have low emissivity so your readings
may also be correspondingly low.
