The T Meter 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.
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 three values stored as follows:
Value 1 – Ra (Roughness Average)
Value 2 – Sp (Concrete Surface Profile – CSP)
Value 3 – STG (Surface Texture Grade)
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.”
