Selection Guide

Shocklog and g-View Quick Selection Guide

If you do not have any non-operating shock specifications for the product you are shipping then use the guide below to assist with your selection.
This is a guide only and not intended to replace actually testing of the product’s shipping properties prior to shipment.
This merely allows you to select an appropriate scale, which then allows the Shocklog or g-View to test the products’ shock profile.
A standard rule of thumb to apply to select an appropriate scale setting is shown below and should be related to the type of product that is to be shipped or the mass of the product.

FAQ's

How do I know which Shocklog product may be the most suitable?

  • If the manufacturer of the product has non-operating shock specifications this will assist greatly with which unit to  select as you will have the known impact or vibration levels that are unacceptable.
  • If the manufacturer of the product has non-operating shock specifications this will assist greatly with which unit to  select as you will have the known impact or vibration levels that are unacceptable.
  • If the above information is not available then we can determine which product may be the most suitable based on the mass of the product. The selection best suited would depend on how much information you want to use.
  • If you require GPS when an event occurs and/or Tilt and Roll monitoring and/or vibration monitoring then you will have to use the Shocklog 298.
  • If you require a detailed event graph when an event occurs then you will either need the Shocklog 298 or 248
  • If you require only a journey graph for each axis then you can use the Shocklog 208.

What is in the ShockLog accessory kit?
The ShockLog accessory kit contains the following items:
1 – ShockLog Software CD (Containing software and user manual)
1 – Quick Start Manual
1 – USB Communication Cable
2 – AA Lithium Batteries
1 – iButton Set (START, STOP, DOWNLOAD, SETUP and CLOCK) – 298 & 248 only
1 – iButton USB Connection BUS and Cable – 298 & 248 only

What is the difference between a slot and a summary?
Slots are user-defined periods of time in which various criteria will be recorded.
Summaries provide an overview of what was recorded by the ShockLog in a given period of time (the summary interval). A summary records the number of warnings/alarms and the maximum recorded slot values in the summary interval.

What is the battery life for a ShockLog unit?
The battery life of a ShockLog unit is dependent upon the type of unit, configuration settings, and the type of batteries being used. With the recommended lithium battery, the ShockLog can have a 9 to 18 month battery life.

What is an event, and how do I record it?
Events are graphical representations of the most severe impacts that the ShockLog is monitoring.
These are set up in the Events tab of the Setup window as warnings and alarms on the Shocklog 298 and 248 only.

What is included in the mounting kit?
The mounting kit contains 4 metal bolts and 4 flex-lock connectors to ensure rigid mounting without any metal-on-metal contact.

I downloaded the data from my unit, and it only recorded slot and summary data for part of the trip. There isn’t a problem with the batteries in the unit. Why did this happen?
When configuring your ShockLog, it is important to have the slots and the summaries last longer than the duration of the journey. These settings can be configured in the Slots tab of the Setup window. In Version 10.2 or newer of the software, you can use the Journey Duration button to determine what these settings should be.

What is the frequency filter?

The frequency filter isolates the impacts recorded by limiting the response to below the frequency factory set in the Shocklog 248. Generally it is based on the mass of the product that you are transporting where more potentially damaging impacts would occur.

How does my ShockLog software license work?

ShockWatch software licensing is intended for a single computer. If you need additional seats or additional computers to use the software, please contact ShockWatch.
Also, please note the following when entering the license code (found inside the software CD case): The code begins with the letters “SW
The license code will not contain the letter “O”; these are zeros (0)

When I connect the ShockLog to my computer using the USB connection, it appears to be running, but when I disconnect it, none of the lights are flashing. Is the unit working?
If no LEDs are flashing after you have sent a setup to the ShockLog and have unplugged the unit, then there may not be any batteries in the unit. Make sure that batteries are installed in the ShockLog unit before sending the setup to the equipment.

When I use the Download iButton, will I obtain all the data from the ShockLog?
Please keep in mind that when the Download iButton is used, no data is erased from the ShockLog unit. Only a limited amount of information is transferred from the ShockLog with the iButton. Primarily, the information obtained is the report displayed on the main screen of the software. Even the events information is limited to the most severe events which have occurred.

Slots Graph (journey profile for each axis)
The ShockLog software allows the user to zoom into specific areas of the Slots
graphs and highlight the key, potentially damaging areas of information.
From the Slot graphs, it is possible to jump to the detailed event curves associated with the period of time being displayed by the slot graphs.

shocklog_event_screen_web_lg
Detailed Event Curve
The event curve displays the detailed data curve for a given event.
The detailed event curve shows the magnitude and duration of the impact event, with the horizontal axis displaying the time in milliseconds and the vertical axis
showing the force of the impact in g. All three axes will be displayed giving users a full understanding of the level of impact seen across all axes
