Selecting Between Air Velocity and Volume (Air Flow)
When an air velocity is displayed on the DC580 the
key can be
pressed to toggle the top display between air velocity and air flow.
Note: The duct size must be entered correctly for the air flow read-
ing to be accurate. Air flow is a calculation based on the duct size
and the measured air velocity.
Storing a Reading
The displayed reading can be stored in memory. This will store the
air velocity, air volume, and temperature.
1. When taking a measurement, once the
reading is on the display press the
key.
2. The display will prompt you for a memory
location to store the reading. To cancel
press the
key or use the
keys to select the
memory location to store the reading then press the
key.
Clearing Memory:
Saving data to the same memory location will
write over the data already saved. All locations can be cleared by
pressing the
key to enter memory mode then pressing and
holding the
key for approximately 3 seconds.
