2.0 DESCRIPTION OF FEATURES
2.1
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.
2.2
Feet / Meters Switch
The
FEET
/
METERS
switch is a two position switch which allows you to
change the display between feet and meters. The up position displays
the depth in feet, down displays the depth in meters. You can change
this switch at any time and the display is automatically updated at that
time.
2.3
Zero Switch
The
ZERO
switch allows you to zero the display, it is a two position
momentary switch. To activate this switch, you must hold the
ENABLE
switch up, then press this switch up.
The rate of increase (or decrease) is controlled by the length of time
the
INCREASE
/
DECREASE
switch is held in position. For small
adjustments, hold the
ENABLE
switch up and jog the
INCREASE
/
DECREASE
switch.
2.4
Increase / Decrease Switch
The
INCREASE
/
DECREASE
switch is a center biased three position
switch. Use the
ENABLE
switch to activate this switch:
Hold both the enable and the increase/decrease switches up and the
display value increases
Hold the enable switch up, and the increase/decrease switch down
and the display value decreases.
