GB | Digital Multimeter

Multimeter MD-220 is a compact, battery-powered, user-friendly

device for measuring alternating and direct current, voltage and

electrical resistance, for testing diodes and transistors and for sound

testing of conductivity. The multimeter was designed in accordance

with the IEC-61010 standard regarding electronic measuring devices

in the category (CAT III 600 V), 2nd degree of pollution.

The CAT III category is used to measure circuits powered by a xed

output power supply, such as a relay, socket, switchboards, power sup-

plies, short branching circuits and lighting systems in large buildings.

Safety Instructions

• Read this manual thoroughly before using the multimeter.

• Always check the connection of testing conductors and measuring

range settings.

• Do not exceed the maximum input limits:

• for AC and DC voltage: 600 V

• for alternating and direct current: 10 A

• Before changing the measuring range (function), disconnect the

conductors from the measured circuit.

Main Features

LCD display: maximum displed value 1999 (3 and 0.5 digits) with

automatic polarity indication

Measuring method: dual – reacts to the pulse leading and trailing

edge

Maximum standard mode: 500 V DC/AC ms

Reading frequency: approx. 2–3 readings per second

Operating temperature: 23°C ±5°C

Temperature range: operating 0°C to +40°C; storage –10°C to

+50°C

Power supply: 9 V battery (1604 or 6F22). The status of the battery

is indicated by the icon on the left side of the display

Dimensions and weight: 85 × 165 × 32 mm, 250 g (including the 9

V battery)

Accessories: Instruction manual, measuring tips

Operating Procedure

a. If the device does not turn on (the display does not light up) or

if the symbol appears on the display upon turning on the

device, the battery is completely drained. Replace the battery.

b. When measuring quantities for which a

symbol is displayed

below the measuring tip connection sockets, do not exceed the

measuring range (risk of damaging the device).

c. If you do not know the approximate voltage or current value

beforehand, set the measuring range to maximum and grad-

ually decrease it as you measure.

d. If the measuring range is exceeded (the display shows the

number "1"), switch to a higher range.

e. Avoid contact with high voltage.

Measuring Direct (DC) Voltage

1. Connect the black measuring tip to the socket labelled as "COM"

and the red conductor to the socket labelled as "V/Ω".

2. Switch to the function marked as V . Choose a measuring range

and place the measuring tips where you wish to measure DC volt-

age. The voltage value and polarity will be shown on the display.

Follow points c), d), e) of the Operating Procedure!

Measuring Alternating (AC) Voltage

1. Connect the black measuring tip to the socket labelled as "COM"

and the red conductor to the socket labelled as "V/Ω".

2. Switch to the function marked as V~. Choose a measuring range

and place the measuring tips where you wish to measure AC

voltage. The measured values will be displayed.

Measuring Direct Current

1. Connect the black measuring tip to the socket labelled as "COM"

and the red conductor to the socket labelled as "mA". To measure

maximum current (up to 10 A), connect the red conductor to the

socket marked as 10 A.

2. Switch to the function marked as A . Choose a measuring range

and place the measuring tips where you wish to measure DC cur-

rent. The current value and polarity will be shown on the display.

• Maximum input current of 200 mA or 10 A depends on which

socket the red measuring tip is plugged into. Excessive current

will destroy the fuse. In that case, it has to be replaced. The 10

A range is not protected by a fuse and can be measured for a

maximum of 15 s, maximum voltage drop of 200 mV.

Measuring Alternating Current

1. Connect the black measuring tip to the socket labelled as "COM"

and the red conductor to the socket labelled as "mA". To measure

maximum current (up to 10 A), connect the red conductor to the

socket marked as 10 A.

2. Switch to the function marked as A~. Choose a measuring range

and place the measuring tips where you wish to measure AC cur-

rent. The current value and polarity will be shown on the display.
