OLED display to provide high performance and low maintenance of non contact temperature measurement in
demanding industrial environment.
2.1 Application, Range and Working Principle
The AST P-GM+ pyrometers are especially designed for glass industries purposes. They are suitable for high
temperature measurement ranging from 250°C to 600°C.
The AST P-GM+ are pyrometers with extended optical head. These instruments are equipped with a fibre optic
and an optical head. The fibre & optical head are unaffected by electromagnetically interferences (e.g. induction) and
can be used in ambient temperatures up to 70°C. The pyrometers are equipped with a display which shows in
measuring mode the current temperature. Via serial interface and the provided software the temperature can be
displayed and stored on a PC, parametrizing can also be done.
AST P-GM+ has response time of 2 msec in triggering mode. It has USB 2.0 output. Emissivity, response time
Peak Picker, Auto OFF Timing and Temperature Hold Time can be can be observed or adjusted through available
optional software.
The pyrometer temperature measurement method utilizes the fact that objects emit thermal radiation in an
amount that directly corresponds to their own temperature and surface emissivity.
The pyrometer sensor detects the amount of infrared radiation emitted by the measured object (target). The
infrared signal is analyzed and the temperature it represents is analyzed by built-in electronic system.
The applications in which AST PGM+ pyrometer can be used is:

Setting at the instrument
4.1 Operation
Before powering ON the pyrometer, make sure that the battery is charged up to some level. AST P-GM+ can be powered
ON by pressing the trigger button for the first time at a single push. After power ON, the device starts an initializing
routine for some seconds. After this the object temperature is shown on the OLED display. The default temperature
value shown should be 249 C when pyrometer is not in front of the target.
It starts measuring the temperature when handle is put in front of the target body. Temperature can be displayed, save
and hold by three different method, i.e. when pressing the button, when releasing the button and holding the peak
value between pressing and releasing the button.
The AST P-GM+ is provided with in built Auto-OFF feature which enable the device to power OFF automatically when
placed in an idle state to save the battery life. The Auto OFF Timing is adjustable from 1 min to 10 min through software.
The battery charging can be done by the external DC charger only provided with the kit. Temperature measurement
cannot be performed while battery charging. Make sure to remove the charger when the battery is fully charged to avoid
any damage to the battery due to over charging. The approximately charging time is around 2:30 hours.
The additional feature is with the temperature measurement OLED display starts blinking to indicate that the measuring
temperature range limit i.e. above 600°C.
Memory reallocation features is provided in which new readings over write on previous readings when 1000 readings is
completed.
4.2 Indications
AST P-GM+ is featured with different indication of
battery status such as low battery, battery charging
and battery full.
It indicates battery level status when powered ON,
after displaying AST logo. It shows full battery(100%)
in terms of 5 Blocks that is 1 block showing 20% level
each.
4.3 Optical Head
The optical head is provided with the rotational
scheme which is beneficial for the user to rotate the
head according to the target required. Head is
provided with 20 rotation for 18° rotation each(Anti-
Clockwise or Clockwise).

4.4Adjustable parameters (Through PC Software)
Emissivity : It is the relationship between the emissions of a
real object and the emission of a black body
radiation source at the same temperature. For a
correct measurement it is necessary to adjust
emissivity. Emissivity depends on the surface
condition of the material, the spectral range of
the pyrometer and the measuring temperature.
Different material has different emissivity
ranging from 0.1 to 1.0. user can change
emissivity from the software through USB.
Temp. Unit : User can select °C or °F unit.
Response time : The response time can be set from 2msec to
10sec.
Clear Memory : User can clear all the saved data from
pyrometer. Before clearing the data, it ask to
save or do not save the recorded data.
Auto OFF Timing : The Auto OFF Timing can be adjustable from 1
min to 10 min maximum.
Temperature Hold Time : It can be set from 1 sec to 30 sec. This time is
use to hold the measured temperature reading
on the OLED display for the desired time.
Temperature Hold on Pressing Button : Temperature data is displayed, saved and hold
on pressing the button.
Temperature Hold on Releasing Button : Temperature data is displayed, saved and hold
on releasing the button. Peak
Temperature Hold between Pressing and Releasing the Button : This feature is used to Hold the Peak value of
the temperature between pressing and
releasing the button.

Software Installation
The provided AST P-GM+ software offers possibilities to connect with your system shows recorded data for
parameter setting, view offline data and to evaluate the measured data.
5.1 Installation
Install the pyrometer software using the installation guide file on CD ROM.After installation of the software.
Double click the application. It will open the screen of software.
5.2 Parameters in main screen
5.2.1 Communication
Communication between the AST P-GM+ pyrometer and the
software is implemented via a USB cable connected between
the pyrometer and the PC serial port. This enables the
acquisition and recording of data, as well as the transfer of
commands from the software application to the AST pyrometer.
When PGM is in OFF condition, a message will appear.
Now ON the PGM and software will auto detect the pyrometer.

A) Emissivity settings : The emissivity can be set by
clicking on "Parameters” and select or type in the desired
emissivity directly in the description field. The emissivity
value will be transferred to pyrometer by hitting the
"TAB" button. The emissivity range is from 0.1 to 1.0.
For a correct measurement it is necessary to adjust the
emissivity. This emissivity is the relationship between the
emission of an real object and the emission of a black
body radiation source at the same temperature. Different
materials have different emissivities ranging
between 0% and 100%. The major parameters effecting
emissivity are:
1. The surface condition of the material, rough surfaces
have higher emissivities.
2. The spectral range of the pyrometer and the measuring
temperature.
3. The Pyrometer spot size is fully filled by measured
object or not.
4. The optical losses due to any obstraction in between
pyrometer & measured object like glass window.
The emissivity setting of the pyrometer has to be adjusted
accordingly. The tolerance of the emissivity values for
each material is mainly dependent on the surface
conditions.
A. 5.2.2Parameter Setting
All user selectable device parameters can be set by using the software in the Panel "Parameter".
