MEASURE
1. Set up the TTT as described in the previous section.
2. Turn TTT on.
3. For ‘SMART’ transducers the TTT automatically shows the transducer input selected (TD#1,
TD#2 or TD#3), the transducers capacity and units. The transducer’s serial number and direction of
linearization (if enabled) are also shown. The instrument then displays the measurement screen.
TD#X
CAPACITY XXXXX N∙m
TRANSDUCER SERIAL # XXXXX
LINEARISED X
NOTE: If the word ‘LINEARISED’ and direction arrows appear on this screen then the TTT is using
a second order polynomial to linearise the transducer.
4. If ‘Menu 2’ is shown, then either:
a) A ‘SMART’ transducer is not connected.
b) The transducer is ‘NON-SMART’.
For ‘NON-SMART’ transducers the transducer details can be saved in the TTT for future use.
Transducer details can be edited, deleted or printed. The last transducer used will always be
retained for quick selection.
Follow ‘measure flow diagram’ in SET UP section & refer to TRANSDUCER INTERFACE section.
TIP: For entry of transducer data, see the ‘USER UNITS’ and ‘USING THE KEY PAD’ sections on
page 11.
c) The ‘Transducer Selection switch’ is in the wrong position.
5. The TRACK screen is now displayed. Exercise the transducer in required direction of use.
6. Press ‘ZERO’ to zero displayed reading.
TIP: The measurement display may not zero if outside +/-3% of transducer capacity. This may be
due to transducer overstrain. Return defective transducer to Norbar.
7. Select measurement mode required.
TIP: If any measurement mode does not memorise the measurement value, ensure that the
‘TRIGGER FROM’ setting is correct. See SETTING, THESHOLDS menu. TRIGGER FROM can
be used to overcome erratic results being obtained.
8. Press to exit any measurement screen and go to SET UP.

Power Saving & Power Down
Battery life can be greatly increased from a minimum of 14 hours by making use of power down. If no key is
pressed or measurement reading taken in the specified time, the TTT will enter power down. The following
will be displayed:
SAVING POWER
PRESS ANY KEY TO CONTINUE
The following features should be noted:
• The POWER DOWN TIME is set in the SETTINGS, POWER DOWN TIME.
• For maximum battery life set POWER DOWN TIME to 1 minute.
• To disable the power down feature set POWER DOWN TIME to 0 (zero).
• The TTT also enters power down when in a set up menu.
• The analogue output will NOT work during power down.
TIP: Check the zero setting of the transducer on return from power down.
When the battery is low there is approximately 20 minutes of use left. In the measure screen a flashing
battery symbol will be seen in the top right hand corner of the display. In a SET UP menu, the following is
displayed:
WARNING #202
BATTERY LOW
PRESS X
When battery is flat the TTT must be turned off or recharged. The following is displayed:
WARNING #201
BATTERY FLAT
SWITCH OFF AND RECHARGE BATTERY
NOTE: From a very flat battery it may take 1 minute of mains power before the display will turn on.

Limits
Limits can be selected In Measure by pressing or .
The target is shown at the top left of the screen and if no limits have been set, the TIME & DATE will be
shown. If limits are available but not selected, ‘↓↑LIMITS OFF’ will be shown.
The limit status is shown in 4 ways:
1. On the display showing LO / OK / HI next to the torque value (updated at 3 Hz).
2. On AMBER / GREEN / RED LED’s on front panel (updated at 208 Hz).
3. On the Serial Port LO / OK / HI is sent before torque value (updated with serial port).
4. On the Ancillaries LO / OK / HI logic outputs (updated at 208 Hz).
TIP: The Ancillaries are updated quickly to give a fast response to an external control system.
NOTE: This difference in update rate may lead to very small differences between the changeover
points.
The LED’s & logic outputs change precisely with increasing torque, and at 0.5% of transducer capacity below
the limit with decreasing torque. This eliminates the logic lines oscillating.
The status of the limits changes as follows:

TRANSDUCER INTERFACE
The 3 transducer connectors are designed for use with most four wire bridge strain gauge type transducers.
When used with Norbar ‘SMART’ transducers the calibration data will be automatically known.
For ‘NON-SMART’ transducers up to 20 sets of transducer parameters can be stored in the TTT for ease of
use. These can be configured with USER units.
TIP: Mark ‘NON-SMART’ transducers with their stored ‘T’ number for ease of identification.
Ensure transducer selection switch is in the correct position for the transducer in use. See the TD#1, TD#2 &
TD#3 symbols next to transducer connectors.
TIP: Press '#' in track mode to show details of transducer in use.
TIP: If any of the transducer’s parameters are changed i.e. re-calibration of mV/V value, the
transducer’s stored parameters must be edited prior to use. (‘NON-SMART’ only).
Norbar transducers with the following suffix are all suitable for use with the TTT:

NOTE: The suffix after the part number indicates the length of the lead in cm, thus
XXXXX.200 = 2 metres. If Transducer leads are required of a non-standard length, the new
suffix must be added to the part number when ordering (to the nearest metre).

External Print / Reset
Pins 1 & 2 are intended for use as an EXTERNAL PRINT / RESET:-
The switch must remain active for at least 200 mS. Screened cable is recommended.
Limit Outputs
Pins 3, 4 & 5 are buffered logic outputs intended for Go/No Go control of external equipment.
All limit outputs are referenced to Pin 9 (Digital 0V). All limit outputs are active HIGH & change at 208 times
per second. For more information on limits, see ‘LIMITS’ menu which can be accessed via the ‘SET UP’
menu.
Limit output current, High = -0.8 mA, Low = 16 mA (not for direct control of relays).
