3. AWE Ended: when both the humidity and temperature signals measured by a probe are stable, the HP23
automatically ends the measurement and freezes the display for that probe. A check mark appears to the left
of the water activity value. In addition the HP23 can be set with the HW4 software to emit an acoustic signal
(Beep) every 5 seconds. The acoustic signal can be stopped by pushing a key (do not press the ENTER key).
When two probes are connected to the HP23, use the UP or DOWN key to verify the status of each probe.
IMPORTANT: do not press the ENTER key until the measurement is ended for both probes.
4. AWE Reset: write down the measurement for each probe or use the automatic data capture function. This
function can be enabled from the keypad: MENU > Aw Mode > SaveResult > ON. The Aw value measured by
probe 1 is saved to Data Bin 1. Probe 2 is saved to Data Bin 2 (see 5.1 Data Capture).
Press ENTER. The HP23 is ready to start a new measurement
