6. General Description

The DVM832 is a battery-operated, hand-held 3 ½ digital multi-meter for

measuring DC and AC voltages, DC current and resistance. It also offers the

DVM832

V. 02 –04/03/2016 6 ©Velleman nv

possibility of executing continuity tests and of testing diodes and transistors.

The back light is optional.

Refer to the illustration on page 2 of this manual:

1. Display (max. 1999 counts, max. 3 ½ digits, dimensions: 47 x 15 mm)

With low-battery indication

2. Rotary switch for manual range selection

This switch is used to select functions and desired ranges as well as to

turn the meter on/off.

3. "VmA" jack

Insert the red (positive) test lead in this connector to measure voltage,

resistance and current (except 10 A).

4. "COM" jack

Insert the black (negative) test lead.

5. "10A" jack

Insert the red test lead in this connector in order to measure a max.

current of 10 A.

Test lead probe: CAT II 500 V/CAT III 300 V, 10 A, L = 90 cm

7. Overvoltage/Installation Category

The applicable categories according EN 61010-1 are:

CAT

A CAT II-rated meter is suitable for measurements in CAT I-

environments and mono-phase appliances that are connected to the

mains by means of a plug and circuits in a normal domestic

environment, provided that the circuit is at least 10m apart from a

CAT III- or 20 m apart from a CAT IV-environment. E.g. household

appliances, portable tools…

CAT

III

A CAT III-rated meter is suitable for measurements in CAT I- and

CAT II-environments, as well as for measurements on (fixed) mono-

or poly-phased appliances which are at least 10 m apart from of a

CAT IV-environment, and for measurements in or on distribution

level equipment (fuse boxes, lighting circuits, electric ovens).

8. Pollution Degree

IEC 61010-1 specifies different types of pollution environments, for which

different protective measures are necessary to ensure safety. Harsher

environments require more protection, and the protection against the

pollution which is to be found in a certain environment depends mainly on

the insulation and the enclosure properties. The pollution degree rating of

the DVM indicates in which environment the device may be used.

DVM832

Pollution

degree 2

Only nonconductive pollution occurs. Occasionally,

temporary conductivity caused by condensation is to be

expected.(home and office environments fall under this

category)

This device is only suitable for measurements in Pollution

degree class 2 environments.

10. Voltage Measurement

Do not measure circuits that may contain voltages > 500 V

Use extreme caution when measuring voltages higher than 60 VDC

or 30 VAC rms.

Always place your fingers behind the protective edges of the test

probes while measuring!

10.1 DC VOLTAGE MEASUREMENT

1. Connect the red test lead to the "VmA" jack and the black lead to the

"COM" jack.

2. Set the rotary switch in the desired V position. If the voltage to be

measured is unknown beforehand, you should set the range switch in

the highest range position and then reduce gradually until the ideal

resolution is obtained.

3. Connect the test leads to the source being measured.

4. Read the voltage value on the LCD display along with the polarity of

the red lead connection.

10.2 AC VOLTAGE MEASUREMENT

1. Connect the red test lead to the "VmA" jack and the black test lead to

the "COM" jack.

2. Set the rotary switch in the appropriate V~ position.

3. Connect the test leads to the source to be measured.

4. Read the voltage value on the LCD display.

11. DC Current Measurement

Do not measure circuits that may contain voltages > 500 V

Use extreme caution when measuring voltages higher than 60 VDC.

Always place your fingers behind the protective edges of the test

probes while measuring!

1. Connect the red test lead to the "VmA" jack and the black test lead to

the "COM" jack (switch the red lead to the "10A" jack for

measurements between 200 mA and 10 A).

2. Set the rotary switch (DCA) in the desired position.

DVM832

V. 02 –04/03/2016 10 ©Velleman nv

3. Open the circuit in which the current is to be measured and connect

the test leads to the circuit IN SERIES.

4. Read the current value and the polarity of the red lead connection on

the LCD display

12. Resistance Measurement

Do not conduct resistance measurements on live circuits. Make sure

all capacitors in the circuit are depleted.

1. Connect the red test lead to the "VmA" jack and the black test lead to

the "COM" jack (the red lead has a positive polarity "+").

2. Set the rotary switch in the appropriate "" range position.

3. Connect the test leads to the resistor to be measured and read the

LCD display.

4. If the resistance being measured is connected to a circuit, turn off the

power and discharge all capacitors before applying the test probes.

13. Diode Testing

Do not conduct diode or continuity measurements on live circuits.

Make sure all capacitors in the circuit are depleted.

1. Connect the red test lead to "VmA" jack and the black one to the

"COM" jack (the red lead has a positive polarity "+".).

2. Set the rotary switch in the " " position.

3. Connect the red test lead to the anode of the diode to be tested and

the black test lead to the cathode of the diode. The approx. forward

voltage drop of the diode will be displayed. If the connection is

reversed, the display will merely show a "1".

14. Continuity Testing

Do not conduct diode or continuity measurements on live circuits.

Make sure all capacitors in the circuit are depleted.

1. Connect the red test lead to "VmA" and the black one to "COM".

2. Set the range switch in the " " position.

3. Connect the test leads to two points of the circuit to be tested. If

continuity exists, the built-in buzzer will sound.
