OM-EL-GFX-TC
K, J & T-type Thermocouple Data Logger
with Graphic Screen
• Compable with K, J and T-type thermocouples with miniature thermocouple
plug connecon
• Stores over 250,000 readings
• Control soware available as a free download
• Logging rates between 2 seconds and 1 hour
• Supplied with 1.0m K-type thermocouple with -80 to +400°C (-112 to +752°F)
measurement range
• On-screen graphing, and menu opons to start, stop, review and restart the
logger in the eld
• Immediate, delayed, push-buon or temperature triggered start mode
This standalone data logger measures and stores more than 250,000 temperature readings from a K, J or T-type thermocouple at a
resoluon of 0.1°C (0.2°F). It comes supplied with a K-type thermocouple capable of measuring from -80 to +400°C (-112 to +752°F).
Your applicaon will determine which probe is most suitable based on temperature range, accuracy, form and price. A wide variety of
alternave thermocouples are available from distribuon.
The user can easily set up the logger and view downloaded data by plugging the data logger into a PC’s USB port and using the free
conguraon soware. Data can then be graphed, printed and exported to other applicaons for detailed analysis.
The data logger features a high contrast dot-matrix LCD and three buons to navigate through an on-screen menu. This menu provides
the user with access to real-me trend analysis, data summaries and the ability to start, stop and restart the data logger without the
need to connect the data logger to the host PC. Users can reset the maximum / minimum reading using the on-screen menu; this
introduces an ‘event marker’ into the data which can later be viewed in the graphing soware (‘Mark Events’ opon) and the data le
aer download.
The data logger is supplied complete with two lithium metal baeries, which can typically allow logging for up to 1 year.

Control Soware
Omega’s control soware is available as a free download from www.omega.com. Easy to install and use, the control soware is
compable with 32-bit and 64-bit versions of Windows XP, Vista, 7 & 8. The soware is used to set up the logger, download, graph and
annotate data or export in Excel, PDF and jpeg formats.
The soware allows the following parameters to be congured:
• Logger name
• Measurement parameter (°C or °F)
• Logging rate (customizable between 1 second and 12 hours)
• High and low alarms
• Immediate and delayed logging start
Download the latest version of the soware free of charge from www.omega.com

PROBE ISOLATION
The K-Type thermocouple probe supplied with the OM-EL-GFX-TC is not electrically isolated from the thermocouple juncon, to
give a faster response.
Depending upon applicaon it may be necessary to use an electrically isolated thermocouple probe to avoid ground loops, and/or
situaons where the probe may come into contact with conductors that are at dierent electrical potenals.
Where doubt exists Omega recommends that electrically isolated probes are always used.
INTERNAL TEMPERATURE ACCURACY
The OM-EL-GFX-TC has the opon to log temperature using an internal sensor. This is selectable using the control soware. The
internal sensor can measure temperature readings over a -30 to +80°C (-22 to +176°F) range, at a resoluon of 0.1°C (0.2°F).

BATTERY INFORMATION
Replacement
We recommend that you replace the baery every year, or prior to logging crical data. Only use 2 x OM-EL-BATT lithium baeries. The
data logger does not lose its stored readings when the baery is discharged or replaced; however, the data logging process will stop
and will not resume unl the baery is replaced and the logger restarted by the control soware.
Before replacing the baery, remove the data logger from the PC. Please note that leaving the data logger plugged into the USB port
for extended periods will cause some of the baery capacity to be lost.
Passivaon
If le unused for extended periods of me, the lithium baeries used in the Omega range of data loggers naturally form a
non-conducve internal layer, prevenng them from self-discharge and eecvely increasing their shelf life. When rst installed in the
data logger, this may cause a momentary drop in the baery voltage (the Transient Minimum Voltage) as the internal layer is broken
down, resulng in the data logger reseng. Inserng the baeries in the data logger and leaving it connected to a PC for about 30
seconds will remove this layer. Aer this, remove and re-install the baeries to reset the data logger. Overall baery life will not be
aected.
WARNING
Handle lithium baeries carefully, observe warnings on baery casing. Dispose of in accordance with local regulaons.
