Spider DSA User’s Manual

Quick Setup Guide

The vibration control system software runs on several different hardware

platforms from Crystal Instruments:

•Spider-81: an 8-channel device that can be expanded to a system with

hundreds of channels

•Spider-81B: a 4-channel economic version of Spider-81

•Spider-80X: a compact packaging of Spider-81 that can be expanded to a

system with hundreds of channels

•Spider-20: a 4-channel handheld Wi-Fi enabled signal analyzer and data

recorder

When there is no confusion, this manual refers the hardware platforms above as

“Spider”. When the description is specifically related to a type of hardware, the

product model number will be mentioned.

Important Safety Information

The Spider product complies with:

EN 61326:1997+A1:1998+A2:2001

EN61000-3-2: 2000 & EN61000-3-3: 1995+A1:2001

The Spider and its accessories should be used only as specified in this User’s

Manual or the warranty protection provided by Crystal Instruments may be void.

Condensation may form on the circuit boards when the device is moved from a

cold environment to a warm one. In these situations, always wait until the device

warms up to room temperature and is completely dry before turning it on. This

acclimatization should take about 2 hours.

For the most accurate measurements, a warm-up phase of 20 minutes is

recommended.

These devices have been designed for use in clean and dry environments. They are

not to be operated in 1) exceedingly dusty and/or wet environments, 2) in

environments where danger of explosion exists, and 3) in environments

containing aggressive chemical agents.

Always lay cables in such a manner as to avoid tripping hazards.

A Warning identifies conditions and actions that pose hazard(s) to the user. A

Caution identifies conditions and actions that may damage the instrument.
