DHS Data Logging System
Installation Guide
Installing the Interface cable
- IFC400 or IFC406
Refer to the “Quick Start Guide” included in the package.
Installing the software
Insert the Software USB stick in an open USB port. If the autorun does not appear, locate the
drive on the computer and double click on Autorun.exe. Follow the instructions provided in
the Wizard.
Device Operation
Connecting and Starting the data logger
- Once the software is installed and running, plug the interface cable into the docking
station.
- Connect the USB end of the interface cable into an open USB port on the computer.
- The device will appear in the Connected Devices list, highlight the desired data logger.
- For most applications, select “Custom Start” from the menu bar and choose the desired
start method, reading rate and other parameters appropriate for the data logging
application and click “Start”. (“Quick Start” applies the most recent custom start options,
“Batch Start” is used for managing multiple loggers at once, “Real Time Start” stores the
dataset as it records while connected to the logger.)
- The status of the device will change to “Running”, “Waiting to Start” or “Waiting to
Manual Start”, depending upon your start method.
- Disconnect the data logger from the interface cable and place it in the environment to
measure. Note: The device will stop recording data when the end of memory is reached or the device is
stopped. At this point the device cannot be restarted until it has been re-armed by the computer.
Downloading data from a data logger
- Place the logger into the docking station.
- Highlight the data logger in the Connected Devices list. Click “Stop” on the menu bar.
- Once the data logger is stopped, with the logger highlighted, click “Download”. You will
be prompted to name your report.
- Downloading will offload and save all the recorded data to the PC.

Product User Guide
Removing the Data Logger from the Thermal Barrier
1. Unscrew the lid of the thermal barrier.
3. Unscrew the HiTemp140-M12 data
logger, from the lid of the thermal barrier.
4. Slide the probe of the data logger out
from the lid of the thermal barrier.
2. Slide out the data logger and lid from
the barrier body.

Product Maintenance
O-Rings
O-ring maintenance is a key factor when properly caring for the HiTemp140-M12. The
O-rings ensure a tight seal and prevent liquid from entering the inside of the device. Please
refer to the application note “O-Rings 101: Protecting Your Data”, found on the MadgeTech
website, for information on how to prevent O-ring failure.
Battery Replacement
Materials: ER1425S-HT Battery
1. Unscrew the bottom of the logger and remove the battery.
2. Place the new battery into the logger. Note the polarity of the battery.
3. Screw the cover back onto the logger.
Recalibration
The HiTemp140-M12 standard calibrations are two points at 50 Ωand 150 Ωand is
verified at 100 Ω.
Pricing:
Recalibration traceable to NIST $70.00
Recalibration only $40.00

Listed specifications can be used to determine maximum allowable exposure times for the HiTemp140
with ThermoVault Max. The barrier extends the operating temperature of the logger up to, but
not exceeding, the measurement range. Please consult the measurement range of the probe for
temperatures above 250 °C (482 °F).
Both the data logger and ThermoVault Max must be at ambient temperature, approximately 25 °C (77
°F) before being placed in the extreme temperature environment. Immediately following exposure to
high temperature, the data logger should be removed from the ThermoVault Max, using appropriate
precautions, as it could be VERY hot. Failing to remove the data logger may allow heat trapped in the
ThermoVault Max to continue to heat the data logger to potentially unsafe levels.
The ThermoVault Max may take hours to fully cool down. Even if the exterior of the ThermoVault Max is
cool to the touch, the interior of the barrier and its contents may still be VERY hot.
The ThermoVault Max is primarily intended for use in dry air environments, but with the addition of the
TMAX Wet Seal Kit, the ThermoVault Max may also be used in liquids and steam environments.
If your application involves a ramp up to a temperature above 150 °C (302 °F) and/or any complex
temperature profile that isn’t a constant process, please contact MadgeTech to determine whether the
HiTemp140 with ThermoVault Max is suitable for the application.
To determine if the HiTemp140 with ThermoVault Max is suitable for the application, please provide
MadgeTech with a detailed description of your process, including temperatures, durations, ramp times
and process media such as air, steam, oil or water. If MadgeTech is unable to definitively calculate the
suitability of our product for your application, a test unit outfitted with a high temperature indicator can
be provided.
