Description
BM6 (cat 40022)
This instrument operates over three ranges, 0-2OOMΩ for insulation testing at 500V d.c., 0- 5000kΩ for resistance and continuity testing at 8,5V d.c., and low voltage continuity testing at 5,5V d.c. over the range 0-200Ω. The 500V test voltage is derived from a transistor oscillator, powered by six, 1,5V HP7 dry cells. The Evershed cross-coils movement requires no setting-up or adjusting, and is individually calibrated.
