1. SAFETY INFORMATION

WARNING

To ensure safe operation, and in order to

exploit to the full the functionality of the meter,

please follow the directions in this section

carefully.

This multimeter has been designed according to IEC-1010

concerning electronic measuring instruments with an

overvoltage category CAT II 1000V, CAT III 600V and

pollution 2.

Follow all safety and operating instructions to ensure that

the meter is used safely and is kept in good operating

condition.

With proper use and care, the digital meter will give you

years of satisfactory service.

1.1 PRELIMINARY

- When using the meter, the user must observe all

normal safety rules concerning:

Protection against the dangers of electrical current.

Protection of the meter against misuse.

- When the meter is delivered, check that it has not been

damaged in transit.

- When poor condition under harsh preservation or

shipping conditions caused, inspect and confirm this

meter without delay.

- Test leads must be in good condition. Before using verify

that the insulation on test leads is not damaged and/or

the leads wire is not exposed.

AMM-1022

- Full compliance with safety standards can be guaranteed

only if used with test leads supplied. If necessary, they

must be replaced with the same model or same electric

ratings.

1.2 DURING USE

- Before using, you must select the right input jack,

function and range.

- Never exceed the protection limit values indicated in

specifications for each range of measurement.

- When the value scale to be measured is unknown

beforehand, set the range selector at the highest

position.

- Do not measure voltage if the voltage on the terminals

exceeds 1000V above earth ground.

- Always be careful when working with voltages above 60V

DC or 30V AC rms, keep fingers behind the probe

barriers while measuring.

- Before rotating the transform switch to change functions

and ranges, disconnect test leads from the circuit under

test.

- Never perform resistance, temperature, transistor, diode

and continuity measurements on live circuits.

- Never use the meter under the condition of the explosive

air, steam or dirt.

- If any faults or abnormalities are observed, the meter can

not be used any more and it has to be checked out.

- Never use the meter unless the rear case is in place and

fastened fully.

- Please do not store or use meter in areas exposed to direct

sunlight, high temperature, humidity or condensation.

1.3 SYMBOL

1.4 MAINTENANCE

- Please do not attempt to adjust or repair the meter by

removing the rear case while voltage is being applied. A

technician who fully understands danger involved should

only carry out such actions.

- Before opening the battery cover or case of the meter,

always disconnect test leads from all tested circuits.

- To avoid the wrong reading causing electricity attack, when

the meter displays “ ”, you must change the battery.

- For continue protection against fire, replace fuse only with

the specified voltage and current ratings: F 200mA/250V

(quick acting).

- Do not use abrasives or solvents on the meter, use a damp

cloth and mild detergent only.

- Always set the power switch to the OFF position when the

meter is not in use.

- If the meter is to be stored for a long period of time, the

batteries should be removed to prevent damage to the unit.

Caution:refer to the instr

uction manual.

Incorrect use may result in damage to the

device or its components.

Earth

This instrument has double insulation.

Fuse: F 200mA/250V
