H25-IR Operation
Instruction 3015-4342 33
TIP: When measuring the total leak-rate of a system, it’s important to clear the log per Section “4.2.10.2
Clearing the Log” before starting a new series of leak-rate measurements.
4.2.10 Logged Measurements
Each of the 50 logged measurements can be individually viewed, or the total accumulated value of all 50
measurements can be displayed. In addition, a log limit can be set that establishes a set point at which a relay
is energized when the total of all logged measurements (up to 50) equals the log limit.
Enter the Log menu by first pressing both the ENT and ESC buttons on either the instrument’s front panel or
Smart probe at the same time to display the Main menu. Next, use the Up and Down buttons to highlight
“LOG”, and then press ENT to display the Log menu.

4.2.10.1 Viewing Logged Measurements
Display the Log menu as described in Section 4.2.10. Next, use the Up and Down buttons to highlight “VIEW
LOG” and then press the ENT button to display the first logged data point.
Use the Up and Down buttons to scroll through the other log points (1 thru 50).
Use the Left or Right button to clear only the current log point. To clear all log points, refer to Section 4.2.10.2
Clearing the Log.
4.2.10.2 Clearing the Log
Display the Log menu as described Section 4.2.10. Next, use the Up and Down buttons to highlight “CLEAR
LOG” and then press the ENT button to display the Clear Log screen.
Press the ENT button to clear the log of all stored measurements.
4.2.10.3 Viewing the Total of All Logged Measurements
The ability to display the total of all logged measurements (up to 50) is useful in situations where it is necessary
to test an installation or piece of equipment that has a maximum permissible total leak rate. For example, a
halogen fire suppression system can have leaks, but the combined leak rate or the sum of all the leaks cannot
exceed a certain level, which is typically specified as a fraction of the total charge per year.
To display the total of all logged measurements, first display the Log menu as described Section 4.2.10. Next,
use the Up and Down buttons to highlight “LOG TOTAL” and then press the ENT button to display the Log
