Figure 5-14. Locked Message for Subsequent Attempts at External Adjustment
NOTE: When an adjustment is in place and locked, an “ADJUSTMENT IS LOCKED” message will be displayed the
next time the operator enters the External Adjustment option by holding the
i
button. The user at this screen
must unlock the adjustment by pressing MODE + SETUP for 3 seconds to unlock the adjustment. The operator
has 1 minute to do this before the screen times out. Pressing ESC will cancel the adjustment routine and return
to normal operation.
If the operator correctly unlocks the adjustment, he is presented the normal EXTERNAL REFERENCE start screen,
followed by the gas selection screen. If the adjustment wasn’t locked to begin with, this same screen would be
presented directly. The user may clear the applied adjustment. Any icons set on the main screens are cleared.
Alternatively, the user may continue and set the adjustment to 1.00 to clear the setting.
5.9. Custom Gas Type Configuration
For a custom gas type, select CUSTOM from the Basic Gas List (refer to Gas Type Menus and Selection on page 47), and
configure the gas using the same procedure used to adjust the H25-IR PRO to a known external leak source that contains the
custom gas. Refer to the previous section (Adjustment to a Known External Leak Source) on page 81.
IMPORTANT: The customer and/or user is responsible for verifying the response of the H25-IR PRO if the custom
gas type option is used.
