Model UT60A: OPERATING MANUAL

Overview

This Operating Manual covers information on safety and cautions. Please read the relevant information carefully and observe all the Warnings and Notes strictly.

Warning To avoid electric shock or personal injury, read the "Safety Information" and "Rules for Safe Operation" carefully before using the Meter.

Digital Multimeter Model UT60A (hereafter referred to as "the Meter") has autorange and manual range options with maximum reading 3999. The enclosure structure design adopted advanced "co-injection" technique in order to provide sufficient insulation.

In addition to the conventional measuring functions, it is equipped with a RS232C standard serial port for easy connection with computer to realize macro recording and monitoring and capture of transient dynamic data, displaying change of waveform during the measurement, providing data and evidence to engineering technicians for scientific research. This is also a highly applied digital multimeter of good performance with full overload protection.

Safety Information

This Meter complies with the standards IEC61010: in pollution degree 2, overvoltage category (CA T. III 1000V, CAT. IV 600V) and double insulation.

CA T. III: Distribution level, fixed installation, with smaller transient overvoltages than CAT. IV CAT IV:Primary supply level, overhead lines, cable systems etc.

Use the Meter only as specified in this operating manual, otherwise the protection provided by the Meter may be impaired.

In this manual, a Warning identifies conditions and actions that pose hazards to the user, or may damage the Meter or the equipment under test.

A Note identifies the information that user should pay attention on.

International electrical symbols used on the Meter and in this Operating Manual are explained on page 8.

Model UT60A: OPERATING MANUAL

Rules For Safe Operation (1)

Warning To avoid possible electric shock or personal injury, and to avoid possible damage to the Meter or to the equipment under test, adhere to the following rules:

l Before using the Meter inspect the case. Do not

use the Meter if it is damaged or the case (or part of the case) is removed. Look for cracks or missing plastic. Pay attention to the insulation around the connectors.

l Inspect the test leads for damaged insulation or

exposed metal. Check the test leads for continuity. Replace damaged test leads with identical model number or electrical specifications before using the Meter.

l Do not apply more than the rated voltage, as

marked on the Meter, between the terminals or between any terminal and grounding.

l The rotary switch should be placed in the right

position and no any changeover of range shall be made during measurement is conducted to prevent damage of the Meter.

l Never working at an effective voltage over 60V

in DC or 30V rms in AC for there is danger of electric shock.

l Use the proper terminals, function, and range

for your measurements.

l Do not use or store the Meter in an environment

of high temperature, humidity, explosive, inflammable and strong magnetic field. The performance of the Meter may deteriorate after dampened.

l When using the test leads, keep your fingers

behind the finger guards.

l Disconnect circuit power and discharge all high-

voltage capacitors before testing continuity, diodes, resistance, capacitance or current.

Rules For Safe Operation (2)

l Before measuring current, check the Meter's

fuses and turn off power to the circuit before connecting the Meter to the circuit.

l Replace the battery as soon as the battery

indicator appears. With a low battery , the Meter might produce false readings that can lead to electric shock and personal injury.

l Remove test leads and RS232C interface cable

from the Meter and turn the Meter power off before opening the Meter case.

l When servicing the Meter, use only the same

model number or identical electrical specifications replacement parts.

l The internal circuit of the Meter shall not be

altered at will to avoid damage of the Meter and any accident.

l Soft cloth and mild detergent should be used to

clean the surface of the Meter when servicing. No abrasive and solvent should be used to prevent the surface of the Meter from corrosion, damage and accident.

l The Meter is suitable for indoor use. l Under the environment with high (+/-4kV)

electrostatic discharge, the Meter may not be operated as normal condition. The user may require resetting the Meter.

l Turn the Meter off when it is not in use and take

out the battery when not using for a long time.

l Constantly check the battery as it may leak when

it has been using for some time, replace the battery as soon as leaking appears. A leaking battery will damage the Meter.
