Height Detection Mode - Panasonic GP-X Series User Manual

3.4.5 Height Detection Mode: "

This mode is convenient to detect the height of a metallic part such as a
screw or rivet etc. After the "height detection mode" is selected, the following
measuring conditions are configured.
・Holding measurement mode is fixed at sample hold.
・The trigger condition is fixed at external trigger.
・The negative direction can be selected for the value displayed according
to the detection distance and inclination of the analog voltage output.
To measure peaks or bottoms continuously varying, select the "manual
mode" and select the suitable holding measurement mode.
Example of height detection
1) Mount the sensor head on equipment.
Prepare the sensor head mounting fitting and an object to be detected.
Reference For the sensor head mounting method, refer to section "1.6.2 Mounting
the Sensor Head" on page 17.
2) Adjust the detection distance.
Prepare a reference sample and adjust the position of the sensor head so that the
height detection range is contained in the detection range (about half the distance)
of the sensor.
3) In the reference position, press and hold the
zero point.
"0.0000" is displayed in the reference position. The analog voltage output is 0V,
too.
Be careful that if the display scale or analog voltage scale has been
changed, an offset corresponding to the scale setting is output.
