1 Amp/250 Volt SuperSting glass tube fuse

What does this fuse do and what is its specification?

This fuse powers the switching electronics in the SwitchBox and the Dual-Mode electrode cables. If blown, Automatic mode surveys will result in all HVOVL. If blown, the relay test will also fail on all relays. However, the Receiver Test using the TestBox (or Adapter Box) will still continue to function.
