testo 350 – Firmware
 
"Firmware" is the internal instrument software that makes our analyzers operate. Like
other software packages, firmware can be upgraded with new analyzer functions for
easier operation, improved performance, additional user calculations, and more.
 
Click here for a detailed description of the latest "Control Unit" and "Analyzer Box"
firmware upgrades.
 
There are different options to performing an upgrade. By following the instructions
below and "doing-it-yourself" you can start using the new functions immediately, or if
you prefer, you can send your analyzer to our service department or have it upgraded
at your next scheduled service checkup.
 
If you do decide to return your analyzer to our service department, please follow a
few steps for returns or if you need help during your do-it-yourself firmware upgrade

(Helpful Hint: In that the original default parameters are automatically reset after an

The Latest Firmware Upgrades Include:
 
Control Unit – New Firmware Upgrade 2.01
New firmware 2.01 for the control unit is needed to operate the new features provided
in the analyzer box.
 
Analyzer Box – New Firmware Upgrade 2.01
The new firmware upgrade now provides the following new features:
 
1. New Sensor Life Diagnostics
As all electrochemical sensors have a defined life span (of about 2-3 years –
concentration dependant) this new feature provides you with a valuable tool that
lets you know when a sensor should be replaced. The remaining sensor life is
displayed as the overall percentage of capacity remaining. Just give us a call and
a new replacement is just an overnight package away. There is no need for you to
carry spare cells.
 
2. New Automatic Testing Programs
The program feature has been upgraded to have multiple automatic testing
programs resident in your analyzer. Now you can select from 5-user defined test
programs for a variety of testing scenarios. Of course the instrument user can
input user defined testing programs as needed.
 
3. Calibration
The sensor calibration procedure has been streamlined and the menu is easier to
understand. You can also protect your calibration by selecting the new password
protection feature. In addition, the Oxygen sensor can now be calibrated at
different concentrations.
 
4. The new Overall Dilution feature extends the range of all the sensors by a
factor of 5. The new firmware utilizes the installed pumps and valves. Simply by
installing this new firmware you analyzer will have the extended ranges without
any hardware change or shipment to service. (this feature only available on
analyzer that have the purge valve installed – typically on kits 3 and 4) – Owners
of 350XL's without the fresh-air valve simply need to install this affordable
upgrade to benefit from Overall Dilution. With this feature, your analyzer has
increased range as follows:
 
CO to 50,00ppm, NO to 15,000ppm, NO2 to 2500ppm, SO2 to 25,000ppm
