Infra-red communications link
The range of the infra-red (IR) link may be reduced in strong lighting conditions or where there is
interference at the specific wavelengths or frequencies used by the IR devices. Sources of such
interference include some fluorescent lighting products. If operation is affected by such conditions,
it may be necessary to reduce the distance between the two units, shield the infra-red ports from
the stray light or use the Duo in its Connected mode.

standard
During the procedure, the display will show the following Sequence.
The control unit must be kept pointing at the traverse unit during this period. Upon successful
completion of the set-up procedure, the display will show a value.
There are five values stored as follows:
Value 1 - gain pot setting
Value 2 - Rz value (21.5+/- 10%)
Value 3 - speed pot setting
Value 4 - Rp value - period of the profile signal (68+/- 2%)
Value 5 - Can be ignored for this procedure.
These values can be viewed by toggling the display using the right-hand Selector button. Should an
error occur during set-up, the procedure will terminate and an E code will be transmitted to the
control unit for display.
“After executing the set-up procedure, the instrument should be calibrated before making any
measurement.”
E codes
The following E codes may appear on the display during the course of using the Surtronic Duo.
E=1. Infra Red communication error. This might be caused by loss of the line of sight between the
two units or other interruption of the infra-red connection. – Repeat the operation.
E=2. Measurement attempted when not calibrated. Calibrate the Traverse Unit.
E=3. Traverse Unit - Oscillator fault - Re-attempt the operation. If the fault persists, return the
Surtronic Duo to a Taylor Hobson Service Centre for servicing or repair.
E=4. Traverse Unit - Motor Positioning fault - Re-attempt the operation. If the fault persists, return
the Surtronic Duo to a Taylor Hobson Service Centre for servicing or repair.
E=5. Traverse Unit - NVRAM Error - Re-attempt the operation. If the fault persists, return the
Surtronic Duo to a Taylor Hobson Service Centre for servicing or repair.
E=6. Profile Over-range. The surface being measured may exceed the measurement range of the
Surtronic Duo. Reattempt the measurement.
E=7. Parameter Over-range. The surface being measured may exceed the measurement range of
the Surtronic Duo. Re-attempt the measurement.
E=8. Traverse Unit - Motor Speed Setup error. Check that the traverse is parallel to the edge of
the calibration standard, then re-try the set-up procedure.
E=9. Traverse Unit - Gain Setup error. Check that the traverse is entirely over the structured area
of the standard. Re-attempt the set up procedure or calibration procedure
E=10. Control Unit - Oscillator fault - Re-attempt the operation. If the fault persists, return the
Surtronic Duo to a Taylor Hobson Service Centre for servicing or repair.
E=11. Traverse Unit - Calibration information download error. Repeat the calibration procedure.
E=12. Traverse Unit - Not set up or set-up information lost. Run the Set up procedure.
E=13. <Reserved>
E=14. Traverse Unit - Electronic Measurement error – Re-attempt the operation. If the fault persists,
return the Surtronic Duo to a Taylor Hobson Service Centre for servicing or repair.

Calibrate using this area
Position the Traverse Unit on the surface to be measured.
If using remote mode, ensure that the line of sight between the infra red
transceivers is unobstructed; maintain the line of sight throughout the
measurement.
To begin the measurement press either of the Start buttons. During the
measurement the Control Unit will show the ‘measurement in progress’
display.
Upon successful completion of a measurement the measured
parameter is displayed as shown.
Should an error occur during measurement an appropriate E code will be displayed.
All parameters (not just the selected parameter) are transmitted to the Control Unit at the same
time and temporarily stored. The stored results may then be stepped through using the Select
buttons.
Calibrating the gauge
To ensure accuracy of results, it is recommended that the Surtronic Duo be calibrated periodically
using the calibration specimen supplied with the instrument.
Position the Traverse Unit to measure the Calibration Standard supplied with the instrument ensuring
that the traverse is parallel to the edge of the standard and entirely over the structured surface. DO
NOT use any other standard.
On the Control Unit press the Mode Select buttons until √is indicated on the Mode status.
Press the Start button on the Control Unit. This will initiate the gauge calibration procedure.
At the end of the calibration procedure the Control Unit will display the results of the calibration.
The Ra value should be 5.81µm and the Rz value 21.5µm. If an error occurs an E code is
displayed.
Set Up Procedure
The Surtronic Duo is set up before leaving the factory. The set-up procedure is used to set the
speed of the traverse unit and the gain of the gauge. Normally it is only necessary to repeat the
set-up procedure after changing the pick-up. However, if it is required to set up the unit after
purchase, the following procedure should be used.
Separate the units ready to use them in Remote Mode.
Turn on the traverse unit and position it on the calibration standard as shown above.
Activate the Control Unit.
With the Control Unit pointing at the IrDA window on the Traverse Unit, press and hold both
selector buttons simultaneously and then press the right-hand start button whilst still holding the
selector buttons. This will initiate the set-up procedure.
Once the procedure has started, release the buttons.
Note that the infra-red link must be maintained throughout the procedure, which takes about a
minute.
