The BM400/2 Series offers a range of single, dual and multi-voltage variants to fit specific applications. The insulation ranges output the nominal test voltage when loaded with 1 mA as specified within these standards. The continuity ranges have a short circuit test current of at least 200 mA. In addition to the insulation and continuity ranges, the BM400/2 series has a resistance range and 2 voltage ranges (except on the BM402/2 and BM404/2). The resistance range measures up to 100k ohm on the digital scale and up to 10 M ohm on the analog scale. Due to the low test voltage and current of this range, the instruments can be used to test circuits with sensitive equipment connected, without causing damage. Applications ELECTRICAL CONTRACTORS The BM400/2 series, designed for flexibility and versatility, has a wide variety of applications and is ideal for testing electrical installations to the British and International Wiring Regulations. Each instrument in the series conforms to the requirements of Table 71 A in BS 7671, and to VDE 0413 parts 1 and 4, HD384 and IEC364. The BM400/2 series can be used in both the domestic and industrial contracting environments. Test voltages of 250 V, 500 V and 1000 V d.c. are available. A 250 V insulation test voltage is necessary to test low voltage circuits supplied by an isolating transformer. 500 V d.c. is the most commonly required voltage, since it is used to test all circuits except low voltage circuits with a nominal voltage up to and including 500 V. The 1000 V d.c. test voltage is used on circuits with a nominal voltage greater than 500 V and less than 1000 V. The continuity ranges can be used to test the continuity of protective and ring final circuit conductors, and the polarity of the conductors. The BM400/2 series instruments can also be used for insulation and continuity tests on transformers, motors, generators, domestic appliances, power tools, such as electric drills, and many other pieces of electrical equipment. On high energy systems it is essential to use test leads with fused prods when measuring voltage. These are available as an optional accessory. SERVICE ORGANISATIONS The BM400/2 series is ideal for use by Service Organisations due to the wide range of parameters which can be measured with the instrument and its associated optional accessories. The insulation test ranges are available for establishing the integrity of the insulation of internal parts such as motors and transformers, as well as other equipment, and the continuity ranges can be used for circuit tracing and operational checking of switches, etc. With the resistance range measuring up to 100 k½ on the digital display, and 10 M½ on the analogue scale, basic components such as resistors, capacitors and diodes can be tested for functionality. Two voltage ranges of 1-50,0 V and 0-600 V a.c./d.c. enable internal mains voltages and power supply rail levels to be measured, and with the addition of the MCC10 optional Current Clamp, appliance current consumptions can be measured and compared to the rating plate. These unique features offer measurement ranges and facilities not normally found in an Insulation Tester and could therefore reduce the number of test instruments required by the Service Engineer. ADVANCED APPLICATIONS The addition of the DLB1 RS232 communication base will enable the BM400/2 family to produce a continuous output of information corresponding to the value which is shown on the instrument display. The DLB1 is supplied complete with AVODATA software which will enable the test information to be transferred to an IBM compatible computer. This opens up applications for continuous monitoring of insulation resistance for the advanced user who may wish to use the results for calculating Dielectric Absorption Ratios including Polarisation Index. The Polarisation Index Ratio is defined as the ratio between insulation resistance values measured after 1 minute and 10 minutes; it is useful for determining insulation quality without the need for temperature compensation or necessary referral to historical test information. The DLB1 when used in conjunction with the SP1 can also facilitate limited remote operation of the BM400/2 series for applications where the product may need to be permanently installed in or near a piece of equipment.
