External power supply is optional only for bridge. Ga anometer uses 2x9V battery.

  • Battery type:6 x 1.5V (LR20) and 2 x9V (6LR61)
  • External Power Input: 3VDC / 4.5A (Input from Jack), 1.5VDC/4.5A (Input from terminal)
  • Dimension: 314 x 276 x 167 mm
  • Weight:  4.5kg

APPLICATION NOTE

  • To measure transformer usually requires long measuring lead wire, the cross section of lead wise shall not be too small, i.e. the resistance of each conductor shall not be greater than 0.1Ω. In this case it is s ested to use special test lead set CD18C or CD19C (optional accessory available on request)
  • DQ-630 clamp device (optional accessory) is available for convenient measurement of resistance of wire and cable per meter.
