6. Prepare for the Duct Leakage Test
6.1
Unpack, connect the gauge to the DucTester
Prior to beginning any test, it is important to verify that the system is functioning properly. Check that
the batteries have enough power, and that the fan can be controlled either automatically or manually.
6.2
Charge the gauge
The rechargeable batteries should be charged when you get it but leave it on the charger overnight to
make sure. These rechargeables will save you about $300 per year so it's worth having a charger with
the equipment and one in your vehicle. Battery life is about 11 hours on a single charge with WiFi
disabled. Battery life will last 9 hours on a single charge with WiFi enabled.
The batteries will charge more quickly if the DM32 is turned off and when plugged to a wall outlet
(instead of to a computer). A large battery icon will be displayed on the screen, as shown below.
