HiTemp140-FP
PRODUCT USER GUIDE
Product Overview
The HiTemp140-FP is a durable, user-friendly high
temperature data logger featuring a long, flexible RTD
probe with a narrow diameter, making it ideal for use in
steam sterilization and lyophilization processes.
Commonly used for mapping, validation and monitoring of
high temperature surfaces, this stainless steel data logger
is available in several models. The flexible probe is coated
with PFA insulation and can withstand temperatures up to
260 °C (500 °F ) with an accuracy of ±0.1.
The HiTemp140-FP probe design is narrow and lightweight
making it ideal for placement within small vials, tubing,
test tube and other small diameter or delicate applications.
Because of the flexible probe, the risks of breakage (both
vial and probe) generally associated with stainless steel
probe loggers are diminished and the location and
placement of the probe is easy to manipulate.
The Trigger Settings feature of the HiTemp140-FP allows
users to configure high and low temperature thresholds
that when met or exceeded, will automatically start or stop
recording data to memory. This data logger is capable of
storing up to 65,536 date and time stamped readings and
features a non-volatile solid state memory which retains
data even if the battery becomes discharged.
Water Resistance
The HiTemp140-FP is rated IP68 and is fully submersible.
Installation Guide
Installing the Software
The Software can be downloaded from the MadgeTech
website at madgetech.com. Follow the instructions
provided in the Installation Wizard.
Installing the Docking Station
IFC400 or IFC406 (sold separately) — Connect the device
into a USB port with the interface cable. The drivers will
install automatically.
Device Operation
Connecting and Starting the Data Logger
1. Once the software is installed and running, plug the
interface cable into the docking station.
2. Connect the USB end of the interface cable into an
open USB port on the computer.
3. Place the data logger into the docking station.
4. The data logger will automatically appear under
Connected Devices within the software.
5. 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.)
6. The status of the device will change to Running,
Waiting to Start or Waiting to Manual Start,
depending upon your start method.
7. 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
1. Place the logger into the docking station.
2. Highlight the data logger in the Connected Devices
list. Click Stop on the menu bar.
3. Once the data logger is stopped, with the logger
highlighted, click Download. You will be prompted to
name your report.
4. Downloading will offload and save all the recorded
data to the PC.

Device Operation (cont’d)
Trigger Settings
The device can be programmed to only record based off
user configured trigger settings.
1. In the Connected devices panel, select the intended
device to change the settings.
2. On the Device tab, in the Information group, click
Properties. Users can also right-click on the device
and select Properties in the context menu.
3. Click Trigger and configure the Trigger settings.
Trigger formats are available in Window and Two Point
(bi-level) mode. Window mode allows for one range of
temperature monitoring and two point mode allows
for two ranges.
Set Password
To password protect the device so that others cannot
start, stop or reset the device:
1. In the Connected Devices panel, click the device
desired.
2. On the Device Tab, in the Information Group, click
Properties. Or, right-click the device and select
Properties in the context menu.
3. On the General Tab, click Set Password.
4. Enter and confirm the password in the box that
appears, then select OK.
Device Maintenance
O-Rings
O-ring maintenance is a key factor when properly
caring for the HiTemp140-FP. 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 at madgetech.com, for
information on how to prevent O-ring failure.
Battery Replacement
Materials: ER14250MR-145 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. It is important to
insert the battery with positive
polarity pointing upward
towards the probe. Failure to
do so could result in product inoperability or potential
explosion if exposed to high temperatures.
3. Screw the cover back onto the logger.
Recalibration
MadgeTech recommends annual recalibration. To send
devices back for calibration, visit madgetech.com.
Notice: Steam Sterilization Applications
The pervasive nature of pressurized steam creates a very
difficult environment for electronics. Please refer to the
following preventative maintenance procedure when
using this device in steam sterilization applications.
Additionally, this device is not ideal for steam sterilization
applications above 121 °C/1.1 bar.
Preventive Maintenance
After every 3 hours of steam exposure:
1. Remove the endcap and battery from the device (ref.
battery change procedure on Product User Guide)
2. Place open logger (minus battery) in an oven at 120 °C
(250 °F) for a minimum of 30 minutes
3. Remove logger from oven and allow to cool to room
temperature
4. Re-assemble the logger with the battery (note polarity)
and endcap
Note: This product is rated for use up to 140 °C
(284 ºF). Please heed the battery warning. The
product will explode if exposed to temperatures
above 140 °C (284 ºF).

Disclaimer & Terms of Use
Published specifications can be used to determine maximum allowable exposure times for the HiTemp140 with Thermal
Shield at different temperatures beyond the normal operating range of the logger. Both the data logger and Thermal Shield
must be at ambient temperature (approximately 25 °C) before being placed in the extreme temperature environment.
Immediately following exposure to high temperature, the data logger should be removed from the thermal shield
(using appropriate precautions, as it could be VERY hot) OR the data logger and shield should be placed in a water bath
(approximately 25 °C) for at least 15 minutes to allow it to cool. Failing to do this may allow heat trapped in the Thermal
Shield to continue to heat the data logger to potentially unsafe levels.
If your application involves a ramp up to a temperature above 140 °C and/or any complex temperature profile that isn’t simply
a constant temperature, please contact MadgeTech to determine whether the HiTemp140 with Thermal Shield is suitable.
Please provide MadgeTech with a detailed description of your temperature profile, including temperatures, durations,
ramp times, and process media (air, steam, oil, water, etc.) If MadgeTech is unable to definitively calculate the suitability of
our product for your application, we can provide a test unit outfitted with a high temperature indicator sticker. This sticker
has an indicator dot which will turn black if exposed to temperatures above 143 °C. Apply the sticker to the bottom of the
data logger itself (not the thermal shield), remove the battery for safety, place the data logger into the thermal shield and
run the assembly through the proposed temperature program. The first indicator dot on the sticker will turn black at 143 °C. If
that happens, the HiTemp140 with thermal shield is not appropriate for the application and we will work to find a solution
that is.
