Warranty and Product Support

Fluke Biomedical warrants this instrument against defects in materials and workmanship for one full year from the date of original purchase.

During the warranty period, we will repair or, at our option, replace at no charge a product that proves to be defective, provided you return

the product, shipping prepaid, to Fluke Biomedical. This warranty does not apply if the product has been damaged by accident or misuse or

as the result of service or modification by other than Fluke Biomedical. IN NO EVENT SHALL FLUKE BIOMEDICAL BE LIABLE FOR

CONSEQUENTIAL DAMAGES.

Only serialized products and their accessory items (those products and items bearing a distinct serial number tag) are covered under this

one-year warranty. PHYSICAL DAMAGE CAUSED BY MISUSE OR PHYSICAL ABUSE IS NOT COVERED UNDER THE WARRANTY.

Items such as cables and nonserialized modules are not covered under this warranty.

Recalibration of instruments is not covered under the warranty.

This warranty gives you specific legal rights, and you may also have other rights which vary from state to state, province to province, or

country to country. This warranty is limited to repairing the instrument to Fluke Biomedical’s specifications.

email techsupport.emea@flukebiomedical.com or call +31-40-2965314.

Claims

Our routine method of shipment is via common carrier, FOB origin. Upon delivery, if physical damage is found, retain all packing materials in their original

condition and contact the carrier immediately to file a claim. If the instrument is delivered in good physical condition but does not operate within specifications, or

if there are any other problems not caused by shipping damage, please contact Fluke Biomedical or your local sales representative.

Returns and Repairs

Return Procedure

All items being returned (including all warranty-claim shipments) must be sent freight-prepaid to our factory location. When you return an instrument to Fluke

Biomedical, we recommend using United Parcel Service, Federal Express, or Air Parcel Post. We also recommend that you insure your shipment for its actual

replacement cost. Fluke Biomedical will not be responsible for lost shipments or instruments that are received in damaged condition due to improper packaging

or handling.

Use the original carton and packaging material for shipment. If they are not available, we recommend the following guide for repackaging:

 Use a double–walled carton of sufficient strength for the weight being shipped.

 Use heavy paper or cardboard to protect all instrument surfaces. Use nonabrasive material around all projecting parts.

 Use at least four inches of tightly packed, industry-approved, shock-absorbent material around the instrument.

Returns for partial refund/credit:

Every product returned for refund/credit must be accompanied by a Return Material Authorization (RMA) number, obtained from our Order Entry Group at 1-

440-498-2560.

Introduction

 Warning

To prevent the possibility of personal injury,

read all safety information before you use the

Product.

This manual is applicable for the VT305 (the Product). It is

a compact, portable and easy-to-use measurement

instrument. The Product measures or calculates:

• Flow

• Volume

• Pressure differences

• High pressure

• Barometric pressure

• Oxygen

• Temperature of gas in the measurement chamber

• Breathing rate

• Inspiratory and expiratory time

• Ratios

• Ti/Tcyc

• Breathing volume

• Volumes per minute

• Peak flow

• Pressure

• Static Compliance (Cstat)

• Triggers (used to separate inspiration time from

expiratory time within each breath).

The Product measures and calibrates parameters on

breathing apparatuses.

Safety Information

A Warning identifies conditions and procedures that are

dangerous to the user. A Caution identifies conditions and

procedures that can cause damage to the Product or the

equipment under test.
