Shock300

PRODUCT OVERVIEW

The MadgeTech Shock300 is a 3-axis shock / acceleration data logger. Each of the three channels may be made active or inactive as needed. Disabling channels will provide additional storage to the enabled channels.

The Shock300 is specifically designed for documenting dynamic environments such as moving vehicles, trucks, containers, ships, etc. The device is also valuable in characterizing environments such as production and assembly lines of delicate electronics, IC fabrication, communications and computer components.

The Shock300 contains two separate accelerometers to provide high sensitivity and accuracy up to 15g or higher levels of shock monitoring up to 300g. One of three operating ranges must be chosen during setup for a logging session. Those ranges are +/- 15g (low g accelerometer), +/- 100g and +/- 300g (high g accelerometer).

Physical Mounting

The most accurate transfer of shock, vibration and acceleration to the final logged data will occur when the mounting is mechanically rigid. Typically, this would occur when the Shock300 is mounted by two bolts directly to a solid metal, flat surfaced object of significant mass.

For various applications, the rigid “bolted down” mounting may not be optimal or practical. The bottom surface of the Shock300 is precision machined flat. It is possible to mount the unit by the use of a doublesided adhesive material. MadgeTech does not make recommendations of specific materials but several points to consider are:

• Adhesive joint should be as thin as possible

Mounting Holes

• Adhesive joint must have adequate strength to support the unit under conditions expected in use (temperature, shock, vibration, etc.)

• Adhesive joint material should be as stiff as possible (high durometer)

The stiffness of the mounting material will affect the transfer of shock or vibration to the Shock300. A soft material will have a tendency to reduce the transfer of high frequencies while a hard material would, in varying degrees, come closer to the fidelity of signal that a bolted down mount would provide.

Orientation of Axes

The illustration to the right shows the directions of the x, y and z axes. They are also laser engraved on the front face of the unit.

If an Shock300 is positioned so that any axis points upward, that axis will report a g force of +1 g.

DEVICE OPERATION

Logging Mode - Peak vs. Instantaneous

When Custom Start is selected in the MadgeTech 4 Software, the user is presented with a range of logging time intervals or actual recording rates (sampling rates). For all but the two highest recording rates, the user will also have a choice of Peak vs. Instantaneous capture.

PEAK

Regardless of the logging interval, the accelerometers will internally sample at 512Hz. At the logging interval (for example,

30 seconds), the Peak value found in the previous logging interval is stored.

INSTANTANEOUS

The accelerometers will only sample data at the logging rate. For instance, if a 30 second logging rate was selected, then only a single data point is captured at each 30 second instant.

The red markers show the peak value for the interval which will be stored.

The potential to lose valuable data can be seen. This, of course, is very dependent on the applied shock duration and wave shape. It’s possible for a significant shock event to occur and not even be visible in the data for the Instantaneous mode.

1. Connect the logger to the interface cable.

2. Highlight the data logger in the Connected Devices list.

3. Click Custom Start .

4. Choose the Start method —Now or Delay (select date and time).

5. Choose the Stop method —Manual or Automatic (select date and time).

6. Select the Reading interval .

7. Select the Shock recording mode (if applicable)—

Instantaneous or Peak

NOTE: When switching USB connections from a PC, laptop or power adapter, users can expect a 2 minute delay.

DEVICE OPERATION

Trigger Mode and Post Trigger Storage

The Shock300 allows the user to enter a shock value which will trigger the storage of data. In general, consider the use of a trigger as primarily a means of saving storage space by saving only data which is above a certain value.

To change a trigger in the MadgeTech 4 Software:

1. Click Properties or right click the device in the

Connected Devices list.

2. Click to enable/disable triggers for the X, Y and Z axis and set trigger points. Trigger setpoints are absolute values.

3. You may also choose between filling all of memory after a trigger or storing only a fixed number of samples after a trigger.

The trigger sample count should be chosen carefully because it may gather data points for which we have no interest. For instance, if 100 were entered and the logging rate were 30 seconds, then 100 data points would be gathered over a 3,000 second interval. There may be very little relevant information to a shock event which triggered the logging process.

While the use of a trigger has a significant effect on data storage, it has virtually no impact on battery life.

Battery Life

The Shock300 battery life is highly dependent on the mode of operation which has been selected for the device. Referring to the Peak and Instantaneous mode discussion, along with the Trigger discussion, the following table presents typical battery life, all at 25 °C, for various applications of the product. At 0 °C, life will be approximately 30% less. At 60 °C, a slight improvement may be seen but is generally masked by increased selfdischarge of the battery.

No difference

(but major storage differences)

For example, if the option to fill memory is selected, then after the first trigger, all of available memory will be filled at the selected logging rate. This will consume the remainder of available storage space for the selected channel.

If instead, a value of 100 is entered for “trigger sample count”, then a total of 100 data points will be stored once a trigger occurs. These 100 samples are acquired at the selected logging rate.

Storage and Data Transfer

The Shock300 contains 8 Megabytes of storage space. This space provides for over 1,397,418 data points for each channel, with all three channels active.

If fewer channels are used, the active channels recover and utilize the unused storage space.

The following table present several examples of storage capacity, measured in days, for various applications of the product.

Many (2)

1. In many cases, the storage space exceeds the battery capacity. In such cases, external power would need to be provided to the Shock300.

2. When logging at a sampling rate (not time) of 128Hz, for example, only 2.84 hours of storage is available without using triggered operation. If trigger is enabled, all storage space is available and is only used for the duration of the triggered shock events, plus a postevent buffer which is user programmable.

PRODUCT MAINTENANCE

Battery Charging and Care

The Shock300 battery does not require any periodic maintenance. It should be charged as needed. If the unit will not be used for a while, leaving the battery in a

50% state of charge is considered beneficial to battery longevity. Using the MadgeTech provided charger is recommended to maintain charging time.

The battery is a Lithium Ion two cell pack. Please note the safe handling and storage recommendations in the specifications section.

Inspection

The Shock300 may be inspected visually for any signs of damage, especially to the gray gasket or to the USB jack. If damage is found, visit madgetech.com
