H25-IR PRO Instruction Manual Operation
P/N: 3015-5678 Rev 6 41
5.3.7. Zero (ENT) Button
The ZERO button manually resets the current gas level to zero. It is also used as the ENT button when
changing configuration values within the menus.
NOTE: Automatic zeroing occurs at startup during initialization. It is therefore
recommended to perform startup of the H25-IR PRO in a refrigerant-free clean-air
environment.
NOTE: In Search Mode, the H25-IR PRO performs an auto zero process to remove the
effects of background refrigerant in the air. Measure Mode does not automatically zero.
Figure 5-5 and Figure 5-6 show a sample Search screen and Measure screen both before and shortly
after the ZERO button is pressed.

on the Diagnostics screen, refer to the Diagnostics Screen section on page 74. Faults and other
diagnostics are displayed in the header portion of the main screen. The
i

with any fault condition to prompt the user to use the
i

NOTE: The Information button is also used to setup a leak reference. For more information, refer to the sections
on Adjustment to a Known External Leak Source (on page 81) and Using a Reference Leak Source (on page 6).
