PRO-TEST OPERATORS HANDBOOK
1.
No display when power is switched on.
a)
Check the Power Supply Module is correctly plugged into the back of the transducer
housing.
b)
Check fuse in mains power plug.
c)
Check the lead is fitted between the display module and transducer.
2.
Readings in First Peak mode are inconsistent.
Change First Peak sensitivity to be less sensitive, see SET-UP MENU section (page 4).
3.
Required units of measurement are not selectable.
a)
Conversion from transducer standard units to required units could not be displayed within
available digits on display, thus conversion is not allowed.
b)
Units required have not been enabled. See SET-UP MENU section (page 4).
4.
RS-232-C data output not communicating with other equipment.
a)
Check that control word on the Pro-Test and the equipment receiving data match. See
page 6.
b)
Check that the baud rate is set to 1200 baud on the equipment receiving data.
c)
Check that the connecting lead is wired correctly at both ends, see page 6.
d)
Check if equipment receiving data requires the units of measurement inhibited or a leading
character. This is applicable when interfacing to Mitutoyo equipment, see page 7.
5.
Display shows zero and does not alter when torque applied.
Switch power off or disconnect at the mains power socket, wait 2 seconds, then power up the
Pro-Test again.
PRO-TEST CALIBRATION AND REPAIR :- _____________________________________________
To maintain the specified accuracy it is recommended that the Pro-Test transducers are recalibrated
at least once per year.
Recalibration and repair should be carried out at Norbar or by a Norbar approved agent, where all the
facilities to ensure the instrument is functioning at maximum accuracy are available.
Alternatively, procedures for calibrating the Pro-Test to the specified accuracy can be found in the
Professional Torque Tester (Pro-Test) service manual Part No. 34240.
CLEANING :- ______________________________________________________________________
Do not use abrasives or solvent based cleaners. We recommend a propriety brand of foam based
fabric / vinyl cleaner. Use a soft cloth to avoid scratches.
