Helpful Hint: When using the FASTMIN mode, if you press the F2 key “Freeze” prior
to LOS, the gauge will display the last minimum prior to the LOS so that the actual
couplant on the end of the transducer is not registered as a legitimate minimum reading.
The parameters that you selected in the Fast option are shown as follows in Measure
mode:
FAST when On is selected
FASTMIN when Min is selected
FASTMAX when Max is selected
<BLANK> when Off is selected
The Fast option allows you to select fast updates of measurements at 20 Hz compared to
4 Hz. If you selected the FastMax option, the LOS will display the LAST MAX
measured value, or if you selected the FastMin parameter the LOS will display the
LAST MIN measured value. If you select the On parameter from the Fast option, the
LOS will work normally and not show the measured reading.
The screens below reflect different parameters selected from the Fast option. For
example, the top screen shows the FASTMAX with LAST MAX measurement on LOS,
and the bottom screen shows the FASTMIN with LAST MIN measurement on LOS.
