Probe end threshold
When the device operates in TBF mode, the probe end threshold value can be changed. The
device uses TBF mode to measure the level of products with low dielectric constants. It uses the
probe end as a reference. If the reflection is very weak, change the probe end threshold to ignore
parasitic signals. Refer to the procedure in How to use thresholds
How to use thresholds How to use thresholds How to use thresholds to change the probe end
threshold.
For more data about the probe end threshold, refer to Function description on page 74 (menu
item 2.5.9).
6.4.9 How to decrease the length of probes
How to decrease the length of single rod probes
• Measure the length of the rod from the flange facing or thread stop. Use a scriber to put a
mark on the rod.
• Cut the rod to the correct length.
• Enter the supervisor menu.
• Push [>>>>], 2 × [
], [>>>>] and 2 × [ ] to go to menu item 2.3.3 PROBE LENGTH.
• Enter the new value. Push [^ ^ ^ ^] to go back to the sub-menu level.
• Push 4 × [^ ^ ^ ^] to save settings.
• Set the parameter to STORE YES and push [^ ^ ^ ^].
How to decrease the length of cable probes
• Loosen the socket set screws that hold the counterweight with a 3 mm Allen wrench.
• Remove the counterweight.
• Measure the length of the cable from the flange facing or thread stop. Use a scriber to put a
mark on the cable.
i Add the length of the counterweight and subtract the length of the cable engaged in the
counterweight. This gives the total probe length. Refer to the illustration and table that
follows.
• Cut the cable to the correct length.
• Attach the cable to the counterweight. Tighten the socket set screws with a 3 mm Allen
wrench.
• Enter the supervisor menu.
• Push [>>>>], 2 × [
], [>>>>] and 2 × [ ] to go to menu item 2.3.3 PROBE LENGTH.
• Enter the new value. Push [^ ^ ^ ^] to go back to the sub-menu level.
• Push 4 × [^ ^ ^ ^] to save settings.
• Set the parameter to STORE YES and push [^ ^ ^ ^].
