January 2009 UDA2182 Universal Dual Analyzer Product Manual 93
While TRV is active, the output can be adjusted using manual mode from the front-panel.
After manual mode is terminated, the output will remain at the level because the output is
tied to TRV.
ATTENTION
Upgrading software on the UDA2182 to a new version will remove PID control (on units where PID has
been ordered or been added in the Field).
Therefore, the following steps need to be followed in order to retrieve that option:
If PID was ordered when the unit was originally ordered:
• Retrieve your Unit ID by going to the MAINTENANCE Æ SYSTEM menu
• Call GTS (1-800-423-9883)
• Inform them that you are going to do a software upgrade and you need the Option ID for your unit
(this is why you need the Unit ID)
• Record Option ID for next step
• After upgrading software, go to MAINTENANCE Æ SYSTEM menu and enter the recorded
OPTION ID
value.
• The PID will have to be reconfigured to settings prior to upgrade.
If PID was added after the unit was originally shipped:
• Before upgrading software, go to MAINTENANCE Æ SYSTEM menu and record the OPTION ID
value.
• After upgrading software, go to MAINTENANCE Æ SYSTEM menu and enter the recorded
OPTION ID
value.
The PID will have to be reconfigured to settings prior to upgrade.
