Entering Threshold Values
Position Teaching
Measurement is actually performed and the measurement results are used to set
threshold values.
Position teaching is useful when threshold samples, i.e., with the upper and lower
limits, can be obtained beforehand.
Hold, trigger mode, and scaling settings that have been made before teaching are reflected in the
teaching measurements.
Moving to the T mode
1.
Set the mode switch to T.
Setting threshold values
2.
Move the threshold switch to either H or L,
i.e., the threshold to be set.
The current measured value is displayed on the main display.
The currently set threshold value (either HIGH or LOW,
depending on the threshold switch setting) is displayed
on the sub-display.
3.
Place the threshold sample in position.
The main display value changes.
4.
Press the ENT key for at least one second
and then release it.
The measured value at the moment that the ENT key is
released is set as the threshold value.
This threshold value is shown on the sub-display.
When [ERRLH] or [ERRHL] is displayed p.65
The threshold values set using position teaching can also be changed using direct input. This is
useful when setting judgment tolerances for measured values.
