303/ThermoLink® Software

The Martel 303 Temperature Meter can be supplied with ThermoLink software and an RS-232 cable which con­nects the 303 to an unused COMM port on a PC or laptop. With the 303 connected to the PC and the ThermoLink
software running, realtime contr ol and analysis of its data can be achieved. With an extended length RS-232 cable,
the 303 Temperature Meter and PC can be used as a remote temperature measurement system.

On start-up, the ThermoLink software automatically scans the available COMM ports
on the PC or laptop, and establishes communication with the 303 Temperature Meter .
Once communications is established, temperature data is continually downloaded
from the 303. The data sampling rate can be adjusted in a number of ways.

Clicking on the Graphical section of the main screen opens a graphic display
of the data being downloaded in realtime from the 303. At the top of the
display is a text field where the time interval between data samples can be
adjusted. A number of the parameters of the graph can be modified to better
display the range of data being displayed. Controls are pr ovided for starting,
stopping, and pausing the recording of data to the graph.

Clicking on the
Control Panel
section of the
main screen
opens an image
of the 303,
which provides
interactive,
realtime control
of all the 303’s
functions.

Clicking on the Auto Arrange section of the
main screen opens the Control Panel,
Realtime Graph, and Tabular windows,
arranged in a non-overlapping display.

Clicking on the Help section of the main
screen accesses an indexed HTML document
that provides detailed information on menus
and controls within the ThermoLink software.

Clicking on the Tabular section of the
main screen opens a tabular display of
the data being downloaded in realtime
from the 303.

Model 303

The 303 is a dual-input, dual display, temperature meter which accepts both
Type-J and -K thermocouples. It features a measurement range of -200 to +760
°C (Type-J) and -200 to +1370 °C (Type-K). REL, HOLD, and MAX/AVG/MIN
functions, and temperature unit selection are available at the push of a button.
Measurement of T1, T2, or T1-T2 is selected by push button as well. An RS232
interface is available for downloading measurement data to a PC for analysis.

306/ThermoLog® Software

The Martel 306 Temperature Meter is supplied with ThermoLog software and an RS-232 cable which connects the
306 to an unused COMM port on a PC or laptop. W ith the 306 connected to the PC and the ThermoLog softwar e
running, realtime control and analysis of its data can be achieved. With an extended length RS-232 cable, the 306
Temperature Meter and PC can be used as a remote temperature data logging and measurement system.

On start-up, the ThermoLog software automatically scans the available COMM ports on
the PC or laptop, and establishes communication with the 306 Temperature Meter , as
shown to the right. Once communications is established, temperature data is continually
downloaded from the 306. The data sampling rate can be adjusted in a number of ways.

Clicking on the Graphical
section of the main screen
opens a graphic display of
the data being downloaded
in realtime from the 306. At
the top of the display is a
text field where the time
interval between data
samples can be adjusted.
A number of the parameters
of the graph can be modified
to better display the range of
data being displayed.
Controls are provided for
starting, stopping, and
pausing the recording of
data to the graph.

Clicking on the DataLogger section of
the main screen opens the data logging
function. Data stored in the 306 Data
Logging Temperature Meter can be
downloaded and displayed for analysis.

Clicking on the
Control Panel
section of the
main screen
opens an image
of the 306, which
provides interac­tive, realtime
control of all the
306’s functions.

Clicking on the Auto Arrange section of

Model 306

The 306 is a dual-input, triple display, Type-K temperature meter with a mea­surement range of -200 to +1370 °C. HOLD, TIME, and MAX/MIN functions,
and temperature unit selection are available at the push of a button. Up to
16,000 records can be stored for downloading to a PC using the supplied RS232
cable and graphing/analysis software.
