The meter uses a preconfigured test sequence to run the leak test based on acceptable flow/volume
limits and time duration. Use the Dresser MeterWare software to change these parameters.
The default is a maximum flow rate of 0.5 cfh with a test duration of two (2) minutes.
After the leak test process completes, either a Leak
Test Pass Screen (Figure 12) or a Leak Test Fail
Screen (Figure 13) displays.
The meter holds this leak test result for 24 hours.
To access this test result within this time, view the
parameter value for LEAKTEST.

Electronic Method – MeterWare Interface
The Leak Test feature is also accessible in the Dresser MeterWare software through the
Advanced
screen,
as shown in Figure 14.
This method requires connecting to the meter by using the IR (infrared) communication cable. The IrDA
cable refers to the IR dongle connected to the USB extension cable. For more information, refer to the
Dresser™ Series D Meter Installation, Operation, and Maintenance Manual
.
With the Dresser MeterWare software, you can adjust the test parameters and run the leak test (refer to
Figure 15).
After the leak test process completes, PASS or FAIL displays on the screen (refer to Figure 16) and on the
meter (as described in Section 7.2).
For more information about running a leak test by using the Dresser MeterWare interface, refer to the
Dresser MeterWare Software Manual
