pro-test operators handbook page 1 of 10 issue 4 august 1998 introduction the pr ofessional torque tester (pro-test) has been designed as an accurate, cost effective and easy to operate instrument for testing and calibrating all types of torque wrenches and torque limiting screw drivers. pro-test transducers are mounted in aluminium cast housings along with all the necessary electronics to produce an output for the display module and rs-232-c interface. the housings can be mounted for either horizontal, clockwise, or anti-clockwise torque testing. the function of the front panel buttons is identified on the display to facilitate quick and easy selection of the operating mode most suitable for the tool to be tested, i.e. track, peak memory with manual reset, peak memory with auto reset, first peak memory with manual reset, or first peak memory with auto reset. these buttons are also used to drive the set-up menus if changes to the operational parameters of the pro-test are required. these include, language of operation, measurement units to be enabled/disabled, rs-232-c communication parameters, auto reset hold time, first peak memory sensitivity and modes of operation to be enabled/disabled. the zero button is only active in the track mode. pro-test transducers are calibrated in the clockwise direction only as standard, the anti- clockwise direction of operation will be inhibited unless the transducer has been additionally calibrated in this direction. the direction of use is identified on the display and rs232c output optional extra?s include a mounting bracket, 1? sq x 36mm hex socket, print inhibit controller, data printer and 12 volt dc power supply for use in vehicles. assembly diagram 43184 38793 62198 (optional) 70 2 holes m10 38796 29179 3/4" to 36mm socket 29189 3/4" to 22mm socket 29134 1/2" to 22mm socket 29067 3/8" to 10mm socket 29190 1" to 36mm socket 2 holes ? 10 25429 43180 pro-test 40 43181 pro-test 400 43182 pro-test 1000 43183 pro-test 1500 43180 pro-test 40 43181 pro-test 400 43189 pro-test 1500er

pro-test operators handbook page 10 of 10 issue 4 aug ust 1998 trouble shooting 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 fus e 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.
