 | To Use an Accelerometer
1. IMPORTANT: Before removing unit
from antistatic bag, attach a ground strap to protect your
accelerometer. Antistatic handling precautions are HIGHLY
recommended.
· The accelerometer will arrive in an ESD bag – we suggest
keeping this bag for reference and future use.
2.
Attach your module to its intended location. The surface must be
very flat and free of debris. Your options include:
· Glue (such as “Super Glue”) or epoxy.
· Attach directly to the surface with screws.
· Attach it to a block or stud-type mount with screws.
· Make sure not to over-torque when using screws.
· It is best to follow the recommendations of the manufacturer of the fastener for the proper bolt torque specification.
· If they do not have a recommendation then use the specifications in the Torque Guide below.
3. Connect the accelerometer’s wiring. This must be done with care.
· Step 1: Make certain all equipment is turned off.· Step 2: Connect the signal wires· Differential mode - Use the positive & negative output wires
· Single ended mode - Use the positive output wires ONLY & tape off all negative output wires
· Step 3: Connect power & ground wires· Be absolutely certain that your power supply voltage is correct for your accelerometer to avoid damage.
· Connect the power (red)
· Connect ground (black)
4. Set the data acquisition system to the appropriate range (+/-
4 volts in differential mode, or .5 to +4.5 volts in single ended mode).
To Remove an Accelerometer
1. IMPORTANT: Before removing
unit, attach a ground strap to protect your accelerometer. Antistatic
handling precautions are HIGHLY recommended.
2. Turn off power and wait a few seconds for power to discharge.
3. Disconnect all wiring.
.
4. Dismount module using care not to damage or contort the housing.
·
If removing from a glued location, do not pry off. Twist off with
a crescent wrench as close to the work surface as possible.
5. Store individually in ESD bags, such as the original packaging. | |

Torque Guide
Use the following dry torque values for non-plated screws.
* Screw size #4-40 coarse thread / 4.9 in-lbs = 78 in-oz
* Screw size #4-40 coarse thread / 10 in-lbs = 160 in-oz
* Screw size 3 mm coarse thread / 6.2 cm-kg = 86 in-oz
* Screw size 3 mm coarse thread / 112.7 cm-kg = 176 in-oz
* Screw size 1/4-20 (for 2230 mounting block) / 6 ft-lbs
* Screw size M6x1 (for 2230 mounting block) / 100 kpsi | Tips:
* For fine thread, increase these values by 9%
* For plated screws decrease torque to 66% of these values
* If lubricating oil is used, decrease torque to 40% of these values |
