f the battery voltage is low, a battery symbol
will be displayed on the screen and soon
afterwards, the wrench will turn off. Replace
with a new set of batteries.
OPERATIONAL OVERVIEW:
Follow the schematics to use the wrench
correctly.
3.2.
Track Mode:
the torque is preset in the set-up
menu. As the wrench applies a turning force, the
read-out will show a continually increasing torque
figure. When 80% of the preset value is
reached, the buzzer sounds intermittently and the
green LEDs flash. When the force reaches
99.5% of the preset value, the buzzer sounds
continually and the red LEDs are fully lit. If the
force applied goes over the stated maximum
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.
3.3.
Peak Hold Mode:
the torque is preset in the
set-up menu as in Track Mode, use the wrench
exactly the same, except that when the force is
released, the display stays at the maximum
torque that has been applied. This value can
then be stored if required (50 memory spaces).
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 nut or bolt.
3.4. Power On.
Place the wrench on a horizontal
level surface and press the ‘C’ button. The
wrench will power-on and auto zero re-set.
If the wrench is not used for two minutes, it will
switch off automatically. Press the ‘C’ button to
power-on the wrench again.
If ‘
Er0
’ appears on the screen during this
process, the wrench has been used at more
than 110% of it’s maximum torque capacity and
this may have caused loss of accuracy and/or
the wrench may have been damaged.
3.5.
Reset in use.
To reset the wrench to zero before
taking the next reading, press the ‘C’ button.
When using Angle Mode, the wrench must
be placed on a horizontal surface to re-set it, if
it isn’t, a series of four zeros will display in the
top half of the LCD screen, Place wrench on a
horizontal surface and press ‘C’ again to re-set.
In Torque Mode, do not apply any external
forces to the ratchet head whilst re-setting.
3.6.
Full reset.
If the wrench appears to malfunction,
or ‘
Er5
’ appears on the screen, remove the
battery compartment cover, replace it and press
the ‘C’ button to re-set the wrench.
3.7.
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.
Selecting Pre-set No.
