Use the Tier Change tool when you upgrade an instrument from version 6 to version 7 software, or when you buy an instrument upgrade. Do the following:
When an instrument is upgraded from version 6 to version 7 software, or when a new version of version 7 is installed, a firmware update may be required. If the firmware version on the instrument is not compatible with the version of software, the instrument will not function properly.
GIM automatically determines if the software and firmware are compatible. The status of compatibility is shown in the Device Info area.
If there is a conflict, this area shows the following:
If the firmware is compatible with software version, the Device Info area will appear as:
NOTE 1: Reference Family instruments only use instrument and communication (comm) firmwares, and do not use a PLD firmware. Interface Family instruments use all three firmwares.
NOTE 2: Gamry does not recommend altering the firmware versions unless necessary.
If no updates are required to use the instrument, this tool is grayed out. When one or more of the firmwares are incompatible, the Auto Update All button is active. This tool automatically selects the compatible firmwares and installs them. To use this tool, take the following steps:
NOTE: Do not power off or disconnect the instrument during this process. Doing so can cause irreversible damage to the instrument.
The Select and Update option is available at all times, even if an update is not required. Gamry recommends not altering the firmware if it is not necessary. This tool allows you to change individual firmwares (instrument, PLD, Comm).
NOTE: Please contact Gamry before making unnecessary modifications to the firmware.
Calibration can be initiated through Framework™, or directly through GIM. Gamry recommends calibrating the instrument at least once per year, or when the quality of your data is in question. To initiate calibration take the following steps:
If there are any failures during calibration, click the Email Results to Gamry Support button in GIM. One of our support engineers will review the results and provide appropriate advice.
