OPERATION
3.1. MODES OVERVIEW:
3.2 In Set Up Mode the 'M' button is used to cycle
through the available options. As each option
appears the up/down arrow buttons are used to
set a value or select a particular option. When
the adjustment/selection is complete the 'M'
button is pressed again to save the settings and
automatically move the display into the next
option. The first option displays the current max.
torque setting. The second option is entitled
nodE and allows the selection of either Track or
Peak Hold mode. The third option is entitled
Unit and allows selection of three alternative
units of measurement (see spec.). The fourth
option will show a memory location number and
this number will alternate with the value stored
there. The fifth option is entitled Clr - and
allows the deletion of the previously displayed
record.
3.3 In Track Mode the torque is preset in the set up
menu. As the wrench applies a turning force to a
bolt the readout will show a continually mounting
torque figure. When 95% of the preset value is
reached the internal buzzer sounds intermittently
and the LED flashes intermittently. When the
force applied goes over the preset torque the
buzzer sounds continually, the LED is fully lit. If
the force applied goes over the stated max.
capacity the LCD display will flash.
NOTE: there is no mechanical 'click' when the
wrench reaches the preset torque. As the turning
force on the wrench is released the digital
readout rolls back down to zero.
3.4 In Peak Hold Mode the torque is also preset in
the set up menu. The action of the wrench is
the same as track mode except that when the
pressure is released the display will stay at the
maximum torque that has been applied. This
value can then be stored in one of 50 memories.
As the ratchet is reversible the wrench can be
used on reverse thread fixings and can also be
used to show the amount of torque required to
undo a particular bolt. For further detailed
information on each mode see the schematics .
3.5 Power On. To turn the wrench on press the 'C'
button. If the wrench is not used for five minutes
it will 'sleep' in power saving mode. Press the
'C' button to reactivate it.
3.6 Reset in use. To reset the wrench to zero before
taking the next reading press the 'C' button.
3.7 Full reset. If the wrench appears to malfunction
press the 'C' button and the 'up arrow' button
together for a complete reset.
3.8 Memory full. If all 50 memories are used 'full'
will appear on the display. It will then be
necessary to clear the memory in set up mode.
