Product Manual 23 M3 Wireless Ultrasonic Level Sensor

13.7 Data Tab

This menu will display the Data History

buffer. It will also allow the sensor to

acquire the range and status information.

You can either acquire and store or not

store the data in the sensors history buffer.

This data can later be retrieved by clicking

the Get History button.

Point the sensor at a wall and press either

the Acquire Data Store or Acquire Data

Don’t Store buttons to obtain the distance

to the wall.

13.8 Waveform Tab

This menu will allow you to acquire the

ultrasonic waveform that can be used for

diagnosing more difficult applications. It

is recommended that new applications

utilize this feature to record events such as

a full tank and an empty tank for archival

purposes. Such events could be detected

for example when the sensor is mounted

near the edge of a tank and a ladder is

detected inside the tank after it empties.

Recommended plots to record are 1

Transmit Cycle at Low Gain and 10

transmit cycles at High Gain. In a typical

plot, the peak signal at the beginning of the

waveform is the transmit burst and the 2

nd

peak is the reflection off the target show

here 60”.

13.9 Programming Tab

This tab allows the sensor’s firmware to be

upgraded. The latest release M3 Software

will contain the latest release firmware.

See http://www.massa.com for the latest

M3 Software and firmware releases. Use

the Firmware Selection dropdown menu

and select the sensor’s correct model

firmware. Note that uploading new

firmware does not affect the sensor’s

configuration registers.

If you require an upgrade of the sensor’s

XBee radio firmware, the “Keep Radio

Awake 2 Min.” button will be used. See

section 13.10 on procedure to upgrade

Xbee firmware.
