9600 Coil Turns Tester
The Coil Turns Tester Type 9600 has been designed to check the number of turns on a winding immediately after it has been wound. Quick and easy to operate, the Type 9600 
provides an instant readout of turns, and performance is not affected by a normal workshop environment. In operation calibration is made against a standard coil.

The coil under test is placed on the appropriate 
platform and the ends of the coil are 
connected to a pair of terminals.
 
The number of turns on the test coil is 
indicated on the digital readout immediately 
after making the connection.

The Type 9600 Turns Tester, which has no moving parts, may be used in conjunction with any of the plug-in platforms described.

• Specification 9600

• Instrument Size 340 x 255 x 115 mm

• Instrument Weight 3.5 kg

Control Software 9600-307 

The 9600-307 Control Software package has been developed to enable the 9600 Turns Tester System to be controlled via an IBM™ or fully compatible PC.
The software also allows re-calibration of the system from data which has been stored in a settings database on a PC. Measurement results are stored in a database which can easily be exported into most spreadsheet programs and subsequently used for projects such as quality analysis, test report writing and similar applications.

System requirement: 486 or above IBM™ or compatible PC with Windows™ 3.1 or above operating system.

The platform Types 9601 and 9602 cover the
most commonly found sizes of wound bobbins or
self supporting coils.
Simple to use, the bobbin is placed over the
probe and the termination leads,
connected to the platform.

The number of turns on the bobbin is then
instantly displayed on the 9600 readout unit.

Specification 9601

• Probe Diameter 10mm

• Accuracy using standard coil supplied 0.5% ± 1 digit

• Accuracy using identical sample 0.2% ± 1 digit

• Will accommodate coils up to a maximum 140 mm high

• or 89 mm outside diameter

• Instrument Size 205 x 305 x 270 mm

• Instrument Weight 1.2 kg

Specifications 9602

• Probe Diameter 6 mm

• Accuracy using standard coil supplied 0.5% ± 1 digit

• Accuracy using identical sample 0.2%± 1 digit

• Will accommodate coils up to a maximum 64 mm high or 50 mm outside diameter

• Instrument Size 205 x 305 x 220 mm

• Instrument Weight 1.1kg

The platform Type 9603 is most suited to the 
smaller sizes of bobbins and coils and is
available with a choice of probe size. 

The standard ‘flat’ probe has a cross-section
of 1.5 x 6.0mm. 
The alternative ‘square’ probe has a cross-section
of 2.5 x 2.5mm. 

In operation the probe must be lifted to allow the test sample to be placed in the measuring position. 
The coil lead-outs are connected to the 
platform and the number of turns is read from the 
9600 readout unit.

Specification 9603

• Designed for small coils

• Supplied with a removable vertical probe

• Probe Size 1.5x6 mm

• Maximum Coil Size 32 x 25 mm outside diameter

• Can be supplied with a probe 2. 5 x 2.5 mm for coils with a smaller inside diameter

• Accuracy using standard coil supplied 0. 5% ± 1 digit

• Accuracy using identical sample 0. 2% ± 1 digit

• Instrument size 205 x 305 x 220 mm

• Instrument weight 1.2k

The platform Types 9604 and 9605 are designed
for the measurement of Larger wound bobbins
and self supporting coils.

In operation the probe must he lifted to allow the
test sample to be positioned in the measurement
area. 
After making electrical connection to the coil 
Ieadouts the number of turns can then he read 
from the 9600 readout unit.

SPECIFICATIONS 9604

• Probe Size 12.5 x 12.5mm

• Maximum Coil Size 102 x 102 x 102mm

• Instrument Size 232 x 148 x 430 mm

• Instrument Weight 3.4kg

• Accuracy using standard coil supplied 0.5% ± I digit

• Accuracy using identical sample 0.2% ±1 digit 

SPECIFICATIONS 9605

• Diameter 28 mm

• Maximum Coil Size 200 x 200 x 200 mm

• Instrument Size 250 x 210 x 730 mm

• Instrument Weight 9.2 kg

• Accuracy using standard coil supplied 0.5% ± 1 digit

• Accuracy using identical sample 0.2% ± 1 digit

The platforms Types 9606 and 9607 are specially
designed to measure toroidal wound coils. 
The 9606 is suitable for small cores and the 
Type 9607 is suitable for the larger varieties.

In operation the probe is pulled forward
and the core is placed over it. 
After returning it to the upright position, the 
level is set to suit the permeability of the
cores being measured.

This is done by adjusting a front panel potentiometer. Electrical connection is made between the 
platform and the coil lead-outs and the 
number of turns is read from the 9600 readout unit.
