Resistance Box Model BR07: 7 decades - 1Ω to 11.11111MΩ
Capacitance Box Model BC05: 5 decades - 0.1nF to 11.111µF
The decade box is built into a metal bench-top box. It is used for testing and cali-
bration.
The main function of these decade boxes is to create a resistance or capacitance
value by using a combination of the rotary decade switches.
They are equipped with Ø 4mm safety terminals for connection.
For safe use, they comply with standard EN 61010-1 (2001).
1.5
The ground (earth) terminal must be connected to a protective ground (earth)
before taking any measurements.
Do not inject any voltage measurements greater than 150V to ground (earth) and
comply with the maximum acceptable current for each decade switch.

Description
Operation
Connect the ground (earth) terminal to a protective ground (earth)
before taking any measurements. Do not forget the resistance of the
measurement leads in the overall accuracy, particularly on the first
decade.
