The Megger AVO835 is an advanced digital multimeter designed for a wide range of applications, with a focus on electrical installation and service applications. The AVO835 has been developed to an ergonomic design with the latest measurement chip-set and live circuit protection. It offers a range of features focused on installation, service and maintenance of electrical applications and equipment, appliance service and utilities.
The AVO835 is custom designed by Megger to fit the needs of the electrical contractor and associated industries. The AVO835 exceed expectations on all measurement levels with excellent resolution, safety and accuracy.
CAT III and CAT IV compliance to IEC 61010*
CAT IV surge protection provides the highest protection in the industry when used on high energy electrical installations, as well as normal mains supplies and electrical equipment.
Phase sequence detection (rotation)
Detection of phase sequence identifies incorrectly wired three phase circuits, motors and generators, to make sure operation is correct and prevent damage or possible electric shock.
Input impedance switching
Unique 10 MΩ and 10 kΩ switching, without changing test range, allows fast and safe detection of unintentionally coupled ghost
voltages. High input impedance does not load the circuit under test, which prevents any significant influence on the voltage.
However, isolated circuits can exhibit a voltage that is capacitance coupled, but with no low impedance source. A low input impedance of 10 kΩ will collapse an unintentionally capacitance coupled voltage, which correctly identifies an isolated circuit.
Non-contact live circuit detection
Non-contact detection of live circuits, cables and conductors. Dual High / Low sensitivity enables the detection of live circuits from a distance, or pinpoint an individual conductor or circuit. Detection is provided by visual (flashing display and symbols) and an audible beep.
High frequency interference filtering
Voltage measurements up to 5 kHz are possible. However, the selectable 800 Hz (3 db) filter prevents the interference of high frequency noise, such as those found on variable speed drive circuits.
LIVE CIRCUIT DETECTION
Safety compliance to combined CAT III 1000 V / CAT IV 600 V for use on high energy, low voltage electrical applications.
Measurement tools
A range of tools are available to help in the capture of difficult measurement quantities, including:
- Minimum and Maximum
- Average
- Hold
- Auto hold
- Smoothing of the measured quantity
