Time Electronics 1061 Resistance Decade Box User Manual

Time Electronics 1061 Resistance Decade Box User Manual

Introduction

A resistance decade box designed to meet the standard required in both educational and industrial applications. Metal film resistors with a 0.75 watt power rating are used throughout, providing the advantages of stability and low temperature coefficient.
The 1061 features six large rotary switches (dials), each with a clear numerical readout that makes resistance setting easy and fast. The robust design provides a durable solution for long term usage, making it ideal for use in education.
The slimline form factor means it takes up minimum bench space, while the 1 % accuracy and wide range makes it suitable for production or select-on-test usage. The case provides complete electrostatic screening. The front panel safety terminals are compatible with 4 mm shrouded plugs, as well as standard plugs, bare wires, and spade terminals.

Operation

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.

Front Panel Controls and Connections

• Resistance Terminals: Resistance is connected via the safety terminal binding posts that are suitable for twisted stripped wire compression connection, spade terminals, or by 4 mm shrouded or normal plug insertion.
• Case Terminal: The case terminal is isolated from the two active resistance terminals. When connected to ground/earth, it may be used as a guard or shield connection, this can help to reduce unwanted electrical noise pickup, and help maintain the case at a safe voltage in certain modes of use.
• Resistance Setting Dials: Used for selecting the required resistance by setting the dial to the value of the decade range. Each dial can be set from 0 to 11. The value is clearly displayed in the white setting window below the decade range.

Operating Instructions

Connections

Connection to the decade box is via 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 and black active terminals connect to the resistance elements, and the green terminal is connected to the case for screening purposes.

For certain applications, the user may want to connect the case terminal to either of the active terminals. This can be done, but the case would then be at the same potential as the active terminals. The user should be aware that this could be hazardous and safety precautions must be taken to prevent electric shock.

Setting Resistance

Use the front panel dials to set the required values according to the decade ranges. The selected value shown in the white setting window under the range arrow. This enables precise setting with a clear unambiguous indication.

For example, to set 1061 Ω:

• Set the 100 kΩ & 10 kΩ to 0.
• Set the 1 kΩ dial to 1.
• Set the 100 Ω dial to 0.
• Set the 10 Ω dial to 6.
• Set the 1 Ω dial to 1.

For a quick reference to the setting values of the 1061, please see the Resistance Setting Table on the following page.

Note: All resistance boxes have a residual resistance, meaning that when the dials are set to zero a small resistance remains. If you are making precision measurements or recalibrating the instrument, this residual value must be subtracted from all measurements.
Typical values of residual resistance are shown in the specifications. For precise values relating to your specific unit, refer to calibration certificate (if ordered).
