Measurements - Leak Detection
The Leak Detection function enables the 716 to test for combustible gas leaks in gas
valves and fittings using the included gooseneck probe.
1. Connect the combustible gas probe to the USB connector located on the top of the
716. See picture below.
2. From the main menu select “Measurement” as
outlined on page 10. From the “Measurements” menu
select “Leak detection” and the following screen will
display.
3. The 716 will begin to countdown from 30. During
this time the combustible sensor is being warmed up
and prepared for use. A light in the sensor cage will
illuminate and can be used to aid in seeing fittings in
dark areas.
4. After the warm-up period is complete the Leak
detection screen will display and a constant tick will
be heard. Use the combustible gas probe to begin
looking for leaks.
5. When a leak is encountered the tick rate will
increase and the Low to High bar graph will visually
indicate a leak. Press the “Zero” key (left blue soft
key) to reset (nullify) the tick and continue looking for
the leak. Repeat this process until the probe is directly
over the source of the leak.
6. Press the “Exit” key (center blue soft key) to return
the 716 to the “Measurements” menu.
