Megger AVO410-US - Digital Multimeter, 1000V DC, 750V AC Voltage, CATIV 600V Rated

The Megger AVO410-US digital multimeter is a true RMS (root mean square) sensing, auto- or manual-ranging meter for measuring current, voltage, resistance, capacitance, and frequency in electrical testing applications. The meter comes with a set of detachable test leads and probes that measure alternating current (AC) and direct current (DC) to 10 amp, AC voltage to 750 volts (V), DC voltage to 1,000V, resistance to 60 megaohms, capacitance to 6 millifarads, and frequency to 60 megahertz (MHz). The microamp reading identifies current changes in flame detector applications. The maximum or minimum reading mode displays the highest or lowest reading in a session to track a sudden increase or decrease in readings. The hold function keeps a reading on the display, even after the meter is disconnected. An audible continuity sensor confirms that the circuit conducts electricity, and a diode test detects proper functioning of a circuit’s diodes. The meter's backlit liquid crystal display (LCD) is readable in low light. The meter has an RS-232 port for connecting the meter to a computer (USB adapter and cable not included). The unit automatically turns off after 10 minutes of non-use to conserve battery life, and a low-battery indicator signals when the meter's batteries need to be replaced. The meter comes with a molded rubber holster that fits onto the meter to help protect against damage from falls, impacts, and abrasion. The meter can survive falls of up to 1.2 meters to a hardwood or concrete floor.

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 rubberized 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 utilizing 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.
