Error conditions

LED indicators
If one of the Input Mode LEDs does not remain on after you connect the probe, an internal probe diagnostic fault exists. Disconnect
and reconnect the probe to restart the power-on diagnostic sequence. If the symptoms continue, connect the probe to another
oscilloscope channel or oscilloscope. If the symptoms remain, return the probe to Tektronix for repair.
There is an amber-colored WARNING indicator LED located on the top plate of the probe comp box. This LED turns on when any of
the following conditions exist and remains on until the problem condition is cleared:
Probe power-on self-test failure (clear by disconnecting and reconnecting the probe)
Probe tip over-temperature detected (may require forced air to be applied to cool the tip)
Probe input over-voltage detected (reduce input over-voltage to clear)
