Ordering Information
The TA280 shock indicators part numbers consist of a basic number, followed by a series of dash numbers, designating configuration, nominal G-rating, and certified tolerance.

Example: TA280-018-015-C5 is an equal-G, front mounting Shockmaster set for 15 G's with a ±5% tolerance, certified.

Shock Indicators Overview
Shockmaster is a low cost, compact mechanical device which can be installed on delicate equipment to detect excessive shock and vibration, thereby assisting in the detection of hidden damage. When a container is opened, following shipment, there may appear to be no damage. However, if the shock indicators are found to be in a "tripped" condition (with bright red signal band exposed in the dome), it is evident that excessive shock has been experienced. Accordingly, a thorough inspection should be made before accepting the shipment.

Instructions for Use

TOLERANCE
Since the springs in the Shockmaster are never elongated, it will remain in tolerance indefinitely, provided it is not subjected to continuous motion of the moving parts and is not contaminated internally with foreign particles. The Shockmaster may be reset and used over and over hundreds of times with no change to its G-rating. Some Shockmasters have been returned for recalibration after 10 years of use, and the units were still within the original factory tolerance.

AREA OF RESPONSE
The Shockmaster has a hemispheric response: it indicates shocks from all directions radial to the unit, axial shocks to the base from beneath, and shocks from all directions between these planes. It will not register axial shocks applied to the dome from above. Models are also available with axial (base) response only. Two shock indicators are usually sufficient for even the largest of packaged items, and one may be adequate if there is no possibility of the equipment being shocked from above.
