7.12 Freeze
The freeze function holds, or freezes, the information on the screen at the moment it is
activated, and the EPOCH 6LT pulser/receiver becomes inactive. No further data is
acquired. A freeze (
) flag appears, indicating that the function is active.
There are two ways to activate the freeze function: manual and automatic. Manual
freeze requires you select the
Freeze button in the sidebar menu to activate the
function. Automatic freeze ( AFreeze ) enables you to automatically activate the freeze
function based on any triggered gate alarm.
When the display is frozen, you can use a variety of instrument functions, including
the following:
• Gate movement
• Gain
• Range and delay
• Rectification
• Data logging
When the freeze function is active, the following parameters cannot be
changed/accessed:
• Zero offset
• Range (cannot be increased)
• Pulser/receiver settings such as PRF , Energy , Mode , pulser waveform, and Filter
To activate the freeze function manually


page 71).
2. On the selected gate, set an alarm (see “Gate Alarms” on page 82).
