1Introduction
A precision decade inductance box suitable for filter design, experimental, general purpose
substitution, and DC to DC converter design. The 1053 is housed in a fully screened robust
metal case and is both compact and durable, making it ideal for laboratory or field use.
Inductance is set by four easy-to-read dials that are divided into 4 decades, and provide
1 mH, 10 mH, 100 mH, and 1 H steps. The maximum setting is 11.11 H. The unit features
custom wound, high permeability ferrite core inductors that ensure insignificant influence
from external magnetic fields and maximum stability.
The front panel safety terminals are compatible with 4 mm shrouded plugs, as well as
standard plugs, bare wires, and spade terminals.
Features
•1 mH to 10 H
•3 % accuracy
•High stability
•In-line readout
•Compact and robust design
•Safety terminals
•Fully screened

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 Front Panel Controls and Connections
•Inductance Terminals: Inductance 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 inductance
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.
•Inductance Setting Dials:Used for selecting the required inductance 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.

3.3 Operating Instructions
3.3.1 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 instability to the inductance reading.
The red and black active terminals connect to the inductance elements, and the green
terminal is connected to the case for screening purposes.
Do not connect to an AC supply above 30 V RMS.
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.

3.3.2 Setting Inductance
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 4.582 H:
•Set the 1 H dial to 4.
•Set the 100 mH dial to 5.
•Set the 10 mH dial to 8
•Set the 1 mH dial to 2.
For a quick reference to the setting values of the 1053, please see the Inductance Setting
Table on the following page.
Note: All inductance boxes have a residual inductance, meaning that when the dials are set to zero a
small inductance remains. If you are making precision measurements or recalibrating the instrument,
this residual value must be subtracted from all measurements.
Typical values of residual inductance are shown in the specifications.
For precise values relating to your specific unit, refer to calibration certificate (if ordered).
