7. Reconfiguring the H25-IR (Replacement of Pre Version 1.4 Modules Only)
NOTE
: Customized system settings are automatically maintained on units that had newer firmware (version
1.4 and newer). However, these settings are reset to their factory default values when replacing the
microprocessor board on units with older firmware (before version 1.4). This section ONLY applies if you
started with an H25-IR having a firmware version prior to 1.4.
IMPORTANT
: A reset to factory defaults occurs automatically on the first boot up with the new module.
Afterwards, the factory menu will be enabled to facilitate the reconfiguring of previous system settings that
were lost as part of the pre 1.4 microprocessor upgrade.
IMPORTANT
: Prior to adjusting settings in the Factory menu, you MUST first adjust the Emitter Power and
DigiPot settings (in that order) in the Diagnostics menu. Then adjust leak source information, followed by the
optional reconfiguration of any other settings that you may have recorded earlier.
NOTE
: Refer to the H25-IR Instruction Manual originally shipped with your unit for additional detailed
information about configuring the IR bench’s emitter power, DigiPot, and leak source settings. If you no
longer have the manual that shipped with your device, the standard H25-IR manual may be downloaded from
the Bacharach website at
www.mybacharach.com
. If you have any questions, you may contact Bacharach’s
Customer Service Department.
1. Adjust the IR bench emitter power first. Refer to the H25-IR manual for details.
2. Adjust the IR bench DigiPot setting. Refer to the H25-IR manual for details.
NOTE
: Following the reset after the microprocessor replacement, the factory menu will
automatically be enabled. Access the factory menu and perform the following steps.
NOTE
: For H25-IR models with an internal leak source, the leak source parameters for the
installed leak source will need to be entered following the reset. These parameters (leak rate and
leak temp) are printed on the ID tag attached to the leak.
3. Adjust the LEAK RATE value to match the internal leak rate in grams per year. This information can be found
on the tag attached to the internal leak source.
4. Adjust the LEAK TEMP value to match the internal leak temperature in degrees C.
5. Restore any additional setup and/or system settings as needed. Refer to the appropriate H25-IR manual for
details.
6. At this point the reconfiguration is complete.
