Frequently Asked Questions


The Monitor test type is used for conducting pressure and temperature monitoring and transient capture, tests that are typically conducted using chart recorders. The Monitor test type provides continuous capture and recording of pressure and temperature data over user specified test durations of up to 48 hours. The data recorded during a Monitor test can be viewed using the companion Windows application pptConnect. This application allows the user to browse test records for all tests recorded by the instrument, view time plots of the pressure and temperature data recorded during digital monitor tests, and generate detailed test reports in PDF format containing test details and data plots (sample below).


"Job-data" is the additional information about the test, which is used to provide complete documentation of the test parameters. Job-data includes the name and company for the individual conducting the test, the location of the test (address, city, state, and zip code), and two lines of user entered job notes. Job notes can be used to enter additional job information, such as detailed location information like a floor or apartment number, or a plumber's license number.

The type of test that the instrument is capable of running is dependent on the sensor connected to the instrument. For example, a 15 PSIG pressure sensor is only capable of supporting the 'fuel gas' and 'drain waste vent' regulatory test types, in addition to Custom, Leak Test and Monitor Test non-regulatory tests. Thus, when prompted to select a test type during the test process, only the applicable test types are available for selection.

Note that the Custom, Leak Test and Monitor Test types are available for all pressure sensors, independent of pressure measurement range.

The PPT instrument includes a set of 'standard' test types that are governed by regulatory codes for the region in which the test is conducted. These codes are used to impose limits on the test parameters (test pressure and duration) established by the user during the test process.

To allow the instrument to be used for tests in a "non-compliant" situation (for example, to conduct a quick one-minute test as a practice run), the 'custom' test type is available to the user. The 'custom' test type has no limits on the test parameters (pressure or duration).

This is a two-part answer:

First, during the test process, the instrument imposes limits on the test parameters (test pressure and duration) based on regulatory code guidelines.

Second, once the test is fully set up, the plumbing-under-test must be pressurized to the user-specified test pressure or greater. The instrument will indicate when a valid pressure level has been achieved. If the pressure in the plumbing is not sufficient, then the test cannot be run.

No, there is not.

Tests results that are "accepted" (by pressing the 'Pass' or 'Fail' button after completion of a test) are stored in log files in the base unit. These files are retained in tamper-proof, non-volatile memory and cannot be altered by the user. Once data is entered into the base unit log file, there is no mechanism for deleting or modifying it.

The instrument logs comprehensive test records for thorough, permanent documentation of each plumbing test. Each test record includes the following information:

  • Date and time at the start and end of the test
  • Test parameters: type, media (gas, water), pressure, and duration
  • Measured pressure and temperature at the start and end of the test
  • Pressure loss and temperature deltas
  • Personnel name and company conducting the test
  • Test location (address, city, state, zip)
  • Test notes (two lines of free-form user entered text)
  • Base unit model, serial, and software version numbers
  • Sensor model, serial number, and calibration date

Test records accumulate in log files contained in the non-volatile memory of the base unit, creating a permanent, tamper-proof record of all tests. The non-volatile memory can store over 1 million test records.

Test data records are stored in "data log" files contained in the base unit non-volatile memory. There are two types of data log files generated in the base unit: the Cumulative log file and Current log files. The Cumulative log file is a single file that contains all test data records generated by the base unit. Current log files are smaller files used to store test records generated since the creation of the Current log file. The base unit History function allows review and printing of data records contained in the Current log file.

The user can create new Current log files using a connected PC running the ppt_host application (downloadable here). Once a new Current log file is created in the base unit, the previous Current log files are not accessible from the base unit History function. However, the files are still accessible to the user using on an external PC connected to the base unit. To access the base unit log files, use the "Upload Log File" feature of the pptConnect application.

The base unit 'History' function allows the user to review past test data, and print test reports for selected tests. Tutorials for this, and other functions can be found on the Support page.


All test results that are accepted by the user are retained in the base-unit's permanent record of tests. If the report you are looking for is part of the Current log file, you can use the instrument's History function to locate the desired test, and then print a test report. You can also use the pptConnect Windows application (downloadable here) to upload the instruments test data, then view data and print detailed test reports for selected records in PDF format.

The Settings function is used for the configuration and maintenance of the instrument. From the Settings menu on the instrument home page, the following operations can be directed:

  • Set the instrument date and time
  • Enable/disable power-saving mode
  • Enable/disable audible and visual alarms
  • Set the default user and company name
  • Set the display precision for pressure measurements

To control the audible and visual alarms:

  • Press the Settings button on the instrument home page.
  • Click the Audible Alarm button to toggle the button state to off.

The button is green when the function is enabled, dark grey when the function is disabled. The Visual Alarm (flashing power button) function is coupled to the audible alarm.

Power-saving mode reduces the screen brightness of the base unit display after 15 minutes of user inactivity (no interaction with the touch display). Power-saving mode is useful when conducting long tests using battery power.

When the base unit enters power-saving mode darkening the screen, full brightness can be restored by pressing any key on the display, waking up the screen.

Please note: while the base unit is in power-saving mode, any key that is pressed will not perform its intended function, instead it will simply wake up the screen restoring it to full brightness, after which all buttons will operate normally.

To disable power-saving mode:

  • Press the Settings button on the instrument home page.
  • Click the Power Saver button.

The button is green when the function is enabled, dark grey when the function is disabled.

The clock in the base unit can be set in two ways.

Setting the clock from the Settings button on the instrument home page:

  • Press the 'Settings' button on the home page. The Settings menu display page shows the current date and time.
  • Press the Set Date/Time button on the Tools Menu.
  • Use the up/down buttons to adjust the date and/or time to the current time.
  • Press the OK button to accept the new date/time, or Cancel button to retain the previous date/time.

Setting the clock from an external computer connected via USB:

  • The base unit clock can be synchronized with local internet time using a connected external PC running the pptConnect application (downloadable from the Support > Downloads page).
  • The external PC must have internet connectivity to use this feature.

The instrument includes a USB port for connection to an external PC (host computer). The utility application pptConnect is designed to operate on the host computer and support various instrument maintenance activities. The following functions are available from the pptConnect application:

  • Synchronize the instrument time with local internet time
  • Upload the log files from the instrument to the host computer.
  • Browse test data records, included pressure and temperature data recorded during Monitor Tests using an easy-to-use interface.
  • Generate detailed test reports in PDF file format from an uploaded log file. The PDF test reports are suitable for printing, emailing, or inclusion in other test documentation.

Yes! All test results on a base unit are available to the user via a connected external PC. To access the entire set of base unit log files, use the "Upload log file" feature of the pptConnect application (downloadable here).
