Operation of the 1053
The 1053 is a compact, robust and accurate decade inductance box suitable for filter
design, experimental, substitution and D.C. converter design.
Its custom wound, high permeability ferrite cores ensure insignificant influence from
external magnetic fields and maximum stability.
The required inductance is set by four dials, divided into decade values.
For example - to set 4.582H
• 1H dial to 4
• 100mH dial to 5
• 10mH dial to 8
• 1mH dial to 2
Connection to the box is via 4 mm safety terminals. Two connections a red and a
black connect to the inductance and the grey terminal connects to the case for
screening purposes.
Note: Remember that all inductance boxes have a residual inductance, i.e.
even when the dials are set to zero there is still an inductance value across
the output. If you are making precision measurements or recalibrating the
instrument, this residual value must be measured and subtracted from all
measurements.
DO NOT CONNECT TO AN A.C. SUPPLY ABOVE 30V RMS.
Clean only with a damp cloth. Use water only. Do not use ammonia or spirit
based cleaners.
