DVM345DI -- DIGITAL MULTIMETER

1. INTRODUCTION

Thank you for buying the DVM345DI. This device enables the user to measure AC and DC

voltages, AC and DC currents, resistance, capacitance and temperature. The device can be

interfaced with a computer and the user can also test diodes, transistors and audible continuity.

2. SAFETY

The meter has been designed according to IEC-1010 concerning the safety requirements for

electronic measuring instruments with an overvoltage category (CAT II) and pollution 2.

Respect the following safety instructions to ensure maximum personal safety and to keep the

device itself in good working order :

• Protect yourself against electroshocks.

• Do not use this device for any other application than those described in this manual.

• Full compliance with safety standards can only be guaranteed if the device is used with the

supplied test leads. If necessary, they should be replaced with identical leads or leads with

identical electric ratings. All test leads should be in good working order.

2.1. Use

• Never exceed the specified limit values for the various measurement ranges.

• Do not touch unused terminals when the meter is connected to a circuit.

• Place the range selector switch in the highest position if the value to be measured is

unknown beforehand.

• Disconnect all test leads from the circuit to be tested prior to selecting a different function.

• When performing measurements on TV’s or switching power circuits, the user should keep in

mind that voltage surges may occur at test points. These surges may damage the meter.

• Never perform resistance measurements on live circuits.

• Exercise extreme caution when working with voltages in excess of 60VDC or 30Vrms AC.

Keep your fingers behind the probe barriers while using the device.

2.3. Maintenance

• Always disconnect the test leads from all current sources before opening the meter.

• Replace blown fuses with an identical one or a fuse with identical voltage and current ratings

(15A/250V).

• Do not use the device and have it checked by qualified personnel if anomalies are observed

or in case of malfunction.

• Use a damp cloth and a mild detergent to clean the device. Never apply abrasives or

solvents to the meter.

3. DESCRIPTION

This device is a professional auto-ranging measuring instrument. All measured values are

displayed on a 3 ¾ digit LCD. The device is equipped with a 38-segment bar graph and can be

used to measure DC & AC voltages (both auto-ranging), DC & AC current, temperature,

resistance (auto-ranging) and capacitance. The user can also test diodes, transistors and

audible continuity.
