will be held for a specified number of readings or until a reading within the gating range

is received. If this is set to "0" then AltTest ignores gating ranges and regards all altitude

readings as valid.

4.

Averaging

 for selecting how many data samples to use when calculating the average

altitude of an altimeter.

5.

Bathymetric  Options

 for entering the velocity of sound when AltTest is used with a

Bathymetric altimeter. Also allows the selection of older "ST" model altimeters.

6.

ASCII Nodes

 for selecting the ASCII Addressed Nodes to be interrogated. Only available

in ASCII Interrogate Mode.

7.

Auto Interrogate

 set to automatically interrogate the altimeter by the interval set. Only

available in ASCII Interrogate or Z Interrogate modes.

Max Log Size

Set the maximum number of records a log file can hold.

Log Path

Set the path to store the log files.

Time Stamp

Check to time stamp each line of log data.

Continue Log

Check to continue logging to a new file once the maximum number of log

records has been reached.

Free Running Mode

Select Free Running Mode for an altimeter which has been configured to operate as a free

running altimeter. The altimeter mode is set by dip switches (see Chapter 6, 

Configuration
