DESCRIPTION

The Megger AVO410 digital multimeter has been designed for the
contracting electrician and has the additional features that also
make the instrument suitable for wide range of applications and
users.

The instrument offers AC and DC voltage and current
measurements as well as resistance, frequency and capacitance
ranges. True RMS readings on the AC functions are standard on the
AVO410 and the instrument features a CATIV 600 V safety rating
meaning the instrument is suitable for industrial applications.

The slim, compact case has a tough rubberised holster that provides
that extra degree of protection from the extreme conditions found
in industrial environments. The style of the case and positioning of
the function switch and buttons means the unit sits comfortably in
the palm for single handed use.

Continuous references to the user guide have been avoided by the
AVO410 utilising simplified functions.

The display features a back light that allows measurements to be
made in poorly lit areas.

The AVO410 test leads are supplied with silicon cable and have
GS38 compliant shrouded tips on the prods.

Auto-ranging

When first selected, all functions are auto-ranging. A range button
on the AVO410 allows multiple manual range selection on each
function; a feature that is generally welcomed by many users.

Minimum / Maximum measurements

The instrument has a MIN MAX function that allows the user to
switch between minimum and maximum measurements. The display
does not have to be continually monitored to capture a momentary
increase or fall in readings.

Data hold

This function allows a displayed result to be frozen on the display
which avoids having to remember a measurement value. The hold
function can be nested within the MIN MAX feature which stops
the AVO410 continuously updating the minimum and maximum
measurement values.

Voltage measurements

Both AC and DC voltage measurements up to 750 V and 1000 V
respectively are possible with the AVO410, the AC reading being a
true RMS value.

Current measurements

For current measurements up to 10 A, a separate fused terminal is
provided to protect both user and instrument from excess current.

RS232

The AVO410 has optically isolated RS232 interface that allows the
user to connect to a PC via a USB port for data acquisition and
analysis. (Optional software is required for this function).

Continuity / diode testing

The continuity function features a buzzer and provides the user
both optical and audio indication of identifying and confirming
continuity between two points. This function also allows forward
and reverse bias testing of diode and semiconductor junctions.

Resistance, capacitance and frequency

Resistance can measured directly on the ohms range from 0 to
60 MΩ with capacitance measurements from 0 to 6.000 mF. In
addition, frequency measurements from 0 to 60 MHz are possible.
