Model UT805: 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 Safety Operation”

carefully before using the Meter.

Model UT805 is a kind of 5 1/2 digit, vacuum-fluorescent,

dual display bench-type true RMS Multimeter (hereafter

referred to as “the Meter”). The Meter’s circuit design

is the combination of large scale integrated simulation

and digital circuit, taking microcomputer technology

with 24 counts A/D converter as a core, highly precise

amplifier, True RMS’s AC converter and full electronic

calibration technique to make it as a reliable and accurate

Multimeter.

In addition to all the conventional features including

DC/AC voltage, current, resistance, diode, continuity

test, capacitance, frequency, there is a recall function.

RS232C and USB 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. This Meter

uses AC power to make it becoming a better electrical

equipment.

Safety Information

This Meter complies with the standards IEC61010: in

pollution degree 2, overvoltage category (CAT. I 1000V,

CAT II 600V) and double insulation.

CAT. III: Distribution level, fixed installation, with smaller

transient overvoltage 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 7.

Rules For Safe Operation

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:

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.

Inspect the test leads and power cord for damaged

insulation or exposed metal. Check the test leads

for continuity. Replace damaged test leads and power

cord with identical model number or electrical

specifications before using the Meter.

Inspect the VFD display for no display..

Do not apply more than the rated voltage, as marked

on the Meter, between the terminals or between any

terminal and grounding.

Model UT805: OPERATING MANUAL

Ensure the Meter is at right measurement position

range. Disconnect the connection between the test

lead and the circuit under tested before changing

over the range. No changeover of range shall be

made during measurement is conducted to prevent

damage of the Meter.

When the Meter working at an effective voltage over

60V in DC or 30V inAC, special care should be taken

for there is danger of electric shock.

Use the proper terminals, function, and range for your

measurements.

Under the manual ranging mode, if the value to be

measured is unknown, use the maximum

measurement position and reduce the range step by

step until a satisfactory reading is obtained.

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.

When using the test leads, keep your fingers behind

the finger guards.

Disconnect circuit power and discharge all high-

voltage capacitors before testing on-line resistance,

continuity, diodes, current, or capacitance.

Before measuring current, check the Meter’s fuses

and turn off power to the circuit before connecting

the Meter to the circuit.

Remove test leads, RS232C interface cable, USB

interface cable and alligator clip from the Meter and

turn the Meter power off before opening the Meter

case.

When servicing the Meter, use only the same model

number or identical electrical specifications

replacement parts.

The internal circuit of the Meter shall not be altered

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

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.

The Meter is suitable for indoor use.

Turn the Meter power off when it is not in use.
