Product Name: Megger BM80/2

Product Description

The AVO Megger BM80/2 is a multi-voltage insulation and continuity tester offering advanced performance, specification and features, and simplicity of use. It has insulation test voltages from 50 V to 1000 V d.c. The analogue/digital LCD incorporates the benefits of electronic arc analogue indication with unambiguous digital readings. The analogue scale helps to make rapid identification of insulation condition, and to monitor variable readings, and is complemented by the precision and simplicity of a digital display. In compliance with BS 7671, IEC 364, HD 384 and VDE 0413 Part 1 and 4, the 250 V, 500 V and 1000 V insulation ranges have a 1 mA test current at the minimum pass values specified. The BM80/2 continuity ranges have a short circuit test current of approximately 205 mA in order to comply with the requirements of these documents. Also on the continuity ranges, is the facility to null the resistance of the test leads. This enables direct readings of low resistance to be taken. A continuity buzzer is included on the second continuity range. In addition to the insulation and continuity ranges, the BM80/2 has a resistance range which measures up to 100 kW on the digital scale and up to 10 MW on the analogue scale. Due to the low test voltage and current of this range, it can be used to test circuits with sensitive equipment connected, without causing damage. Two voltage ranges measure up to 50,0 V and 600 V a.c. or d.c. respectively, and indicate the presence of negative d.c. A voltage warning is provided, alerting the user to the presence of external voltage greater than 25 V, by displaying the voltage level, even when measuring on insulation and continuity ranges. The voltage range will indicate if capacitive charge remains after a test, and will monitor the automatic discharge. Testing is inhibited if 55 V is detected. Hands free operation is offered as standard except the insulation ranges. Locking and non-locking test buttons are provided with each instrument for user selection. Use of the non-locking button is recommended to prevent accidental mis-use and injury, and in cases where continuous operation of an insulation test is required the locking button can be fitted. Alternatively the optional accessory Switched Test Probe SP1 can be used enabling remote operation of the test button from the negative test probe. The BM80/2 series is rugged, and therefore suited to tool bag treatment, as well as having an IP54 environmental protection rating which ensures product reliability in wet and dusty conditions. Exceptional battery life is provided by six cells housed in separate battery compartment. The instruments are designed to IEC 1010-1, VDE0411 and BS4743 safety standards.
