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 Total screen. Note that the display is auto ranging, causing the decimal point to turn off above the value 99.9. In the example below, the total of all logged measurements is 78.5 Oz/yr.

COMBINED LEAK RATE = 78.5 Oz/yr

4.2.10.4 Setting the Log Limit

The ability to set a log limit is useful when using the H-25IR to log the leak rate of a system that has a maximum permissible total leak rate. A relay can be programmed to energize when the total of all logged measurements (up to 50) equals the log limit (refer to Section 2.4.3 Relays).

To set the log limit, first display the Log menu as described in Section 4.2.10. Next, use the Up and Down buttons to highlight “LOG LIMIT” and then press the ENT button to display the Log Limit screen. Use the Left and Right buttons to move the blinking cursor across the screen to highlight the digit to be modified, and then use the Up and Down buttons to modify that digit. Press ENT to save the log limit value and return to the Log menu.

LOG LIMIT

IS 999.00 Oz/yr
