- Screw type tip holder. Set screw used for immobilizing the probe tip.
- 0.1mA leakage current @ 5V
- Capacitance to ground is 2 pF @ 100khz
The TH series of tip holders relies on the micropositioner itself to provide electrical isolation. The micropositioner part that supports the TH piece, is electrically isolated from the micropositioner base with a flat section of insulating material and teflon sleeves around the retaining screws. The TH type is the most economical tip holder, but the trade off is in increased current leakage.
