1Safety Requirement

1.1 General Safety Summary

Please review the following safety precautions carefully before putting the instrument

into operation so as to avoid any personal injury or damage to the instrument and

any product connected to it. To prevent potential hazards, please follow the

instructions specified in this manual to use the instrument properly.

1 Only the exclusive power cord

designed for the instrument and

authorized for use within the

destination country could be

used.

9 Do not operate the instrument

with suspected failures.

2 Ensure that the instrument is

safely grounded.

10 Provide adequate ventilation.

3 Observe all terminal ratings. 11 Do not operate in wet conditions.

4 Use proper overvoltage

protection.

12 Do not operate in an explosive

atmosphere.

5 Do not operate without covers. 13 Keep instrument surfaces clean

and dry.

6 Do not insert objects into the air

outlet.

14 Prevent electrostatic impact.

7 Use the proper fuse. 15 Handle with caution.

8 Avoid circuit or wire exposure.

WARNING

Equipment meeting Class A requirements may not offer adequate protection to broadcast

services within residential environment.

1.3 Measurement Category

Measurement Category

This instrument can make measurements in Measurement Category I.

WARNING

This instrument can only be used for measurements within its specified measurement

categories.

Measurement Category Definitions

• Measurement category I is for measurements performed on circuits not directly

connected to MAINS. Examples are measurements on circuits not derived from

MAINS, and specially protected (internal) MAINS derived circuits. In the latter

case, transient stresses are variable. Thus, you must know the transient withstand

capability of the equipment.

• Measurement category II is for measurements performed on circuits directly

connected to low voltage installation. Examples are measurements on household

appliances, portable tools and similar equipment.

• Measurement category III is for measurements performed in the building

installation. Examples are measurements on distribution boards, circuit-breakers,

wiring (including cables, bus-bars, junction boxes, switches and socket-outlets) in

the fixed installation, and equipment for industrial use and some other

Safety Requirement

equipment. For example, stationary motors with permanent connection to a

fixed installation.

• Measurement category IV is for measurements performed at the source of a

low-voltage installation. Examples are electricity meters and measurements on

primary overcurrent protection devices and ripple control units.

1.4 Ventilation Requirement

This instrument uses a fan to force cooling. Please make sure that the air inlet and

outlet areas are free from obstructions and have free air. When using the instrument

in a bench-top or rack setting, provide at least 10 cm clearance beside, above and

behind the instrument for adequate ventilation.

CAUTION

Inadequate ventilation may cause an increase of temperature in the instrument, which

would cause damage to the instrument. So please keep the instrument well ventilated and

inspect the air outlet and the fan regularly.

1.5 Working Environment

Temperature

Operating: 0℃ to +50℃

Non-operating: -30℃ to +60℃

Humidity

• Operating:

Below +30℃: ≤90% RH (without condensation)

+30℃ to +40℃: ≤75% RH (without condensation)

+40℃ to +50℃: ≤45% RH (without condensation)

• Non-operating:

Below +60℃: ≤90% RH (without condensation)

WARNING

To avoid short circuit inside the instrument or electric shock, never operate the

instrument in a humid environment.

Altitude

• Operating: below 3 km

• Non-operating: below 15 km

Safety Requirement

Protection Level Against Electric Shock

ESD ±8kV

Installation (Overvoltage) Category

This product is powered by mains conforming to installation (overvoltage) category II.

WARNING

Ensure that no overvoltage (such as that caused by a bolt of lightning) can reach the

product. Otherwise, the operator might be exposed to the danger of an electric shock.

Installation (Overvoltage) Category Definitions

Installation (overvoltage) category I refers to signal level which is applicable to

equipment measurement terminals connected to the source circuit. Among these

terminals, precautions are done to limit the transient voltage to a low level.

Installation (overvoltage) category II refers to the local power distribution level which

is applicable to equipment connected to the AC line (AC power).

Pollution Degree

Pollution Degree 2

Pollution Degree Definition

• Pollution Degree 1: No pollution or only dry, nonconductive pollution occurs.

The pollution has no effect. For example, a clean room or air-conditioned office

environment.

• Pollution Degree 2: Normally only nonconductive pollution occurs. Temporary

conductivity caused by condensation is to be expected. For example, indoor

environment.

• Pollution Degree 3: Conductive pollution or dry nonconductive pollution that

becomes conductive due to condensation occurs. For example, sheltered

outdoor environment.

• Pollution Degree 4: The pollution generates persistent conductivity caused by

conductive dust, rain, or snow. For example, outdoor areas.

Safety Class

Class 1 – Grounded Product

1.6 Care and Cleaning

Care

Do not store or leave the instrument where it may be exposed to direct sunlight for

long periods of time.

Safety Requirement

Cleaning

Clean the instrument regularly according to its operating conditions.

1. Disconnect the instrument from all power sources.

2. Clean the external surfaces of the instrument with a soft cloth dampened with mild

detergent or water. Avoid having any water or other objects into the chassis via the

heat dissipation hole. When cleaning the LCD, take care to avoid scarifying it.

CAUTION

To avoid damage to the instrument, do not expose it to caustic liquids.

WARNING

To avoid short-circuit resulting from moisture or personal injuries, ensure that the

instrument is completely dry before connecting it to the power supply.
