Suitable For Applications to CATIII 600 V
The AVO300 range of Megger digital multi-meters are tough compact instruments designed for the contracting electrician, but are also suitable for a wide range of applications and users.
Both instruments offer a range of measurement modes for AC and DC applications, resistance and current measurement
The AVO300 series multi-meters have tough rubber armoured cases offering the maximum amount of protection from the extreme use found in modern industrial environments. They draw on extensive experience of Megger engineers in designing safe reliable instruments for the electrical industry.
Neither of the instruments are burdened with functions that never get used. This keeps the instruments simple to operate without the continued need to refer to the user manual.
Every measurement range is fully auto-ranging. Simply switch on the instrument and start testing, leaving hands free for holding probes, or hanging onto ladders.
Separate Battery/Fuse compartment
The battery and fuse compartment are accessed by a separate cover on the back. This allows both battery and fuses to be replaced without opening the main instrument body, and if the meter is sealed with a calibration seal, will not break the seal and invalidate the calibration. A problem found on most commonly available multi-meters.
Large Clear Display
The LCD display has large high contrast 31/2 digit display which are easily read from a distance. Additionally the AVO310 has a backlit LCD for use in poor lighting.
This allows a displayed result to be held on the display until needed, rather than trying to remember a measurement. The result will be held until the HOLD button is pressed again, or until the unit switches off
When making current measurements the mode function allow the selection of AC or DC measurement.
*MAX/MIN (AVO310 only)
The Max/Min function on the AVO310 freezes the maximum or minimum measured result on the screen. The display does not have to be continually watched to capture a momentary increase or fall in circuit voltage, resistance or current
Both AC and DC voltage measurement is possible with the instrument auto ranging to match the voltage at the test probes. Voltage measurements up to 1000 V are permitted without damage to the instrument.
Three ranges are provided for current measurement of either AC or DC current from 0.1 uA to 10 A. Fused inputs protect both the user and the instrument in the case of excess current.
Resistance, Continuity and Diode Testing
Resistance can be measured directly on the ohms range from 0Ω up to 1.999 MΩ. A continuity buzzer range is also available for checking low resistance between two points. The buzzer sounding if the resistance is less than 50Ω (35Ω on the AVO310).
Additionally a diode range exists for testing forward and reverse bias operation of transistors and diodes
A low battery indicator warns when batteries are low, and an auto-off function ensures no unnecessary battery wastage occurs if accidentally left on. A built-in rear stand provides both a bench stand for comfortable use on the bench, as well as extending round 180° to act as a hanging bracket.
