28 ST60 Depth Instrument Owner’s Handbook
Setting offset values
WARNING:
The use of incorrect offset values could result in misleading depth
information being displayed with a consequent risk of running
aground.
Use the offset (decrement) and reset (increment) keys to set the required offset
value.
If you want to display the actual depth reading from the transducer, set a value of
0.0.
If you want to apply a W/L (water line) offset or a KEEL offset, adjust the
displayed reading until the correct offset value is shown (positive for W/L ;
negative for KEEL ).
Shallow lock
When set to On, prevents inadvertent alteration to the shallow depth alarm
setting.
Note:
The procedure for setting alarm threshold levels is given in Chapter 1, Operation.
Pop-up pilot
Switches the pop-up pilot function on and off.
Leaving User calibration
Hold down the depth and alarm keys for 2 seconds to save your settings, exit
User calibration and resume normal operation.
4.3 Intermediate calibration
Intermediate calibration enables you to:
• Check the instrument software version.
• Set the instrument status - either MASTER or REPEATER . This feature is par-
ticularly useful in preventing interference when using another product (e.g. a
fishfinder) that operates at 200 kHz.
