1Introduction
A compact 5 fixed value resistance box designed for industrial, general laboratory, and
education requirements. Housed in a robust case the 1068 is easily portable and takes up
minimal bench space. Being a low cost and simple operation instrument, it is a popular
model for physics and electronics laboratories in universities and schools.
The high accuracy obtained in the 1068 is achieved by the use of precision resistors.
To select a value simply connect test leads to one of the fixed value resistors; 1Ω, 10Ω,
100Ω, 1kΩ, or 10kΩ.
Connection to the box is via safety terminals that are compatible with 4 mm shrouded plugs,
as well as standard plugs, bare wires, and spade terminals. The resistance values are
clearly indicated beside each terminal.
Features
•5 fixed resistance ranges
•High accuracy
•Clear visual indication
•Portable and compact
•Simple operation
•Robust casing
•Ideal for education

3Operation
3.1 Safety Precautions
Observe proper safety operational guidelines when working with high voltages.
To minimize shock hazard connect the case terminal to an electrical ground.
Always take precautions to avoid and prevent contact with live components.
Handle the unit with care and use as per the instructions in this manual.
3.2 Operating Instructions
Connection to the box isvia 4 mm safety terminal posts, using 4 mm shrouded or standard
plugs. Alternatively, crocodile clips or stripped wire connections can be used.
Whatever method is used, the connection must be tight to the terminal posts to avoid
introducing unwanted additional resistance.
The red terminals connect to the resistors with the common black negative.
To use the box simply connect to the resistor you require.
