5. When a thickness measurement is
displayed the display also shows the
Measurement Mode and the Units.
SE = Single Echo mode
EE = Echo-Echo mode
ME = Multiple Echo mode

Echo Indicators in Multiple Echo Mode

Should the gauge be unable to detect a stable multiple echo signal
it displays an Echo indication to help the operator locate a suitable
position.
1. 1 Bar Flashing:
No echoes detected
2. 1 steady + 1 Bar Flashing:
Only 1 echo detected
3. 2 steady + 1 Bar Flashing:
Only 2 echoes detected
4. 3 steady + 1 Bar Flashing:
3 echoes detected but they are not
matched
To help obtain a multiple echo reading the operator should
continue to move the probe around to locate a suitable reflector,
using a slight rocking motion.
Measurement Stability Indication in SE & EE Modes
To help indicate when a Single Echo or Echo-Echo measurement is
stable – and thus probably reliable – the gauge changes the
thickness measurement number from Hollow to Solid when the
measurement has been stable for 2 consecutive seconds.
When measuring using Single Echo or Echo-Echo mode once you
have a measurement keep the probe still and wait for the gauge to
signal a "stable reading".
