Introduction

Thank you for purchasing TPI products. The 285 is easy to use and built to last. It is backed by a three

year limited warranty. Please visit www.testproductsintl.com to register your meter.

Product Description

The slim design 285 is a hand-held, auto ranging clamp-on DMM with Bluetooth output for use with the

TPI View app. Backlit dual display, True RMS response, Frequency with Duty Cycle, Min/Max/Avg,

Temperature, Inrush Current measurement, Capacitance, DC microamps, and Non-Contact Voltage

detection are just a few of the features of the 285.

The TPI View app can be used in conjunction with the 285 to store measurements to jobs, create and

email test reports, view live readings from a safe distance, or print measurements to the optional A711BT

printer.

Contents

The 285 comes complete with the following accessories:

Carrying Pouch

Test Lead Set

Temperature Probe

Instruction Manual

Battery & Fuse

TPI View App

The TPI View app is available for Android and iOS devices. Visit the Play Store or the App Store to

Safety

Please follow manufacturers test procedures whenever possible. Do not

attempt to measure unknown voltages or components until a complete

understanding of the circuit is obtained.

Veuillez suivre les procédures de test des fabricants dans la mesure du

possible. N'essayez pas de mesurer des tensions ou des composants

inconnus jusqu'à ce qu'une compréhension complète du circuit soit obtenue.

Read instructions before operating:

Be sure these instructions accompany the tool when passed from one user to a new or

inexperienced user.

If test equipment is used in a manner not specified by the manufacturer, the protection provided

by the equipment may be impaired.

GENERAL GUIDELINES

ALWAYS

•

Test the 285 before using it to make sure it is operating properly.

•

Inspect the test leads before using to make sure there are no breaks or shorts.

•

Double check all connections before testing.

•

Have someone check on you periodically if working alone.

•

Have a complete understanding of the circuit being measured.

•

Disconnect power to circuit, then connect test leads to the 285, then to circuit being measured.

NEVER

•

Attempt to measure unknown high voltages.

•

Attempt to measure DC microamps with the meter in parallel to the circuit.

•

Connect the test leads to a live circuit before setting up the instrument.

•

Touch any exposed metal part of the test lead assembly.
