3.0 DESCRIPTION
OF
FEATURES
3.1 Enable
Switch
The
ENABLE
/
OFF
switch is a center-biased three position switch. If you
push the switch down, the magnetic pickup stores the displayed value
in the non-volatile memory and switches the unit off if not on external
power.
The unit cannot be switched off when connected to external
power.
The display unit forces you to use two switches, to prevent accidental
loss or corruption of the depth display value.
The up position (
ENABLE
) does several things:
The unit powers on, and the unit re-displays the stored value.
Enable is also required to zero or increase/decrease the depth.

This button is used to change the internal settings of the panel.
These settings include Measuring Head type, Line Size settings, Load
Cell Angles, English/Metric units, Depth adjust (auto add/subtract),
etc. Refer to section 4 for detailed description of these features.

ZERO
switch allows you to zero the display, it is a two position
momentary switch. To activate this switch, you must hold the

the

adjustments, hold the

switch up and jog the

/
DECREASE
switch.

off of battery power.
