H25-IR Operation

4.2.9 Logging Measured Readings

The H25-IR can log up to 50 measurements, which can then be viewed and analyzed at a later time. Each logged measurement is given a date & time stamp for identification. The measurements are stored in non- volatile memory, and will not be erased when the instrument is turned OFF.

With the instrument in its Measure mode, press the LOG button to log the measurement that is currently being displayed on the Data Display screen. Note that logged data is stored on a first-in, first-out basis. Once 50 measurements have been stored, the newest stored measurement overwrites the oldest.

NOTE: Only non-zero measurements will be logged.

In the following example, a reading of 0.48 Oz/yr is about to be logged in memory location 11. Pressing the ENT button will confirm this action and then display a Measurement Logged screen, which confirms that the data has been saved while also showing the current total of all leaks logged.

IMPORTANT! The instrument does not perform a units-of-measure conversion. It is therefore very important that the operator not change the leak units value after beginning to log measurements.

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 Working with 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 setpoint 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.
