1. Introduction & Safety Prescriptions

To all residents of the European Union

Important environmental information about this product

This symbol on the device or the package indicates that disposal of the device after its lifecycle could harm

the environment.

Do not dispose of the unit (or batteries) as unsorted municipal waste; it should be taken to a specialized

company for recycling.

This device should be returned to your distributor or to a local recycling service.

Respect the local environmental rules.

If in doubt, contact your local waste disposal authorities.

Thank you for buying the DVM52IT! Please read the manual carefully before bringing this device into service.

The meter was designed according to IEC 348 and according to IEC-1010 concerning the safety requirements for

electronic measuring instruments with an overvoltage category (CAT II) and pollution 2. This manual contains a

number of safety prescriptions that must be followed to the letter. Read these instructions before using the device!!

Injury or death can occur even with low voltages and low current. Consequently it is extremely important that you

read these safety instructions before using your device. Follow all safety and operating procedures as described in

this manual.

• Protect yourself against electroshocks.

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

• Make sure the device was not damaged in transit.

• Make sure the insulation of the test leads is not damaged and/or the wire itself is not exposed.

• 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.

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

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

• Do not measure voltages > 1000V above earth ground.

• 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.

• Do not connect the leads to a voltage source while the function switch is in one of the following modes: insulation

resistance, resistance or continuity.

• Never perform measurements on live circuits.

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

• Have the device checked by a qualified technician in case of malfunction.

• Never use the meter if the back panel is not in place and firmly fixed.

• Do not use or store the device in areas exposed to direct sunlight, high temperatures or high humidity.

3. Maintenance

• Do not remove the back cover while a voltage is being applied. Only a qualified technician should handle repairs.

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

• Always place the function and range switches in the OFF position when the device is not in use.

• Remove the batteries to keep them from leaking if the device is to be stored for a prolonged period of time.

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

4. Description

General

• This digital insulation tester is equipped with two alarm functions. A humming sound is produced every two

seconds to prevent damage from improper operation when the function or range switch is in the wrong position.

• Press the test button and the alarm system will produce a humming sound every two seconds. The high voltage

output indicator will flash red, warning the operator of the risk of electroshocks because of the high output voltage.

• The device is protected against overload and a low-battery indication is provided.

• The device also has a data-hold function.

• Two rotary switches are used to select the functions and ranges.

• The DVM52IT has a test button that can be locked. Releasing the test button automatically discharges the

capacitance of the device.
