User Manual

DIGITAL VOLMETER-AMMETER

Read all the instructions carefully

The EV2M meters are digital multimeters to measure TRMS values (true

root mean square values) for alternate voltage and current. It reads these two

quantities simultaneously on two 3-digit LED displays.

SAFETY WARNINGS

During the installation and operation of the instrument, proceed in accordance

with the instructions below:

1) The instrument should be installed by a competent operator following the

installation diagrams carefully

2) Before touching the connector terminals make sure that the wires to be connected

or already connected to the instrument are not live

3) The instrument should be installed in a panel from which no access can be gained

to the terminals after installation

4) Do not power or connect the instrument if any part of it is damaged

5) The electrical system of the building in which the instrument is to be installed

should have a switch and a protective device against over-currents

6) The instrument is designed for installations with over-voltage category III and

pollution level 2, in accordance with the EN 61010-1 standard.

RESOLUTION AND ACCURACY

• Voltage (full scale V MAX

= 600 V):

– Maximum reading: 615 V

– Minimum reading: 10V

– Resolution: 1V

– Accuracy: ± 0,5% full scale ± 1 digit (from 3% to 100% of full scale value)

• Current (full scale In = 5 A):

– Maximum reading: 6 A

– Minimum reading: 0,02 A

– Resolution: 0,01 A

– Accuracy: ± 0,5% full scale ± 1 digit (from 3% to 100% of full scale value)

Note: current data refer to the values provided by the amperometric transformer;

maximum and minimum readings directly depend on the AT ratio used, whereas

resolution is dependent on the scale used, as described below.

OPERATION

During normal operation the device reads the Voltage value (Volts) in the top window and the

current value (Amperes) in the bottom window.

The current value is automatically read in the most appropriate scale:

• 0,01 A resolution in the 0,02 A ÷ 10 A range (e.g.: )6.47

• 0,1 A resolution in the 10 A ÷ 100 A range (e.g.: )39.1

• 1 A resolution in the 100 A ÷ 1000 A range (e.g.: )528

• 10A resolution for values above 1000 A (e.g.: : )1.03

In the latter case the value is expressed in kA with the decimal point lit after the first digit and

the LED point lit to the right of the last digit above the kA symbol

SETTINGS

After switching the device on it is possible to check and/or change some of the factory settings

by pressing or holding down the key according to the procedure described below.Prg

• Press the Prg key

The voltage and current reading displays will read a value

referring to the transformer primary (factory setting: 5).

To change this value, hold down the key for at least 2 Prg

seconds until the digits ﬂ ash. Then press and hold the key

pressed until the desired value is reached (the reading will

increase by 5-unit steps; 1000 is read as ).001.

• After a few seconds from the moment the key is released, a value

will indicate the reading ﬁ lter (factory value: 10). The lower this

value, the faster the readings will be updated, the higher the

value, the more stable the reading will be.

To change this value, hold down the key for at least 2 Prg

seconds until the digits ﬂ ash. Then press the key repeatedly

until the desired value is set (the reading will increase by 1-unit

steps; the value range is from 1 to 20).

After one of these parameters is set the device will go off and

then on again using the new parameters. The device is reset

automatically with no need to disconnect it from the power supply.

ERROR MESSAGES

• Memory error: EEE

The device has undergone damage that jeopardizes operation

• Overload error: KKK

The quantity measured (voltage and/or current) has exceeded the

maximum admissible value: V > 1,02 x VMAX; I > 1,2 x In.

Reset is automatic.
