set when a power sensor is disconnected.
• STATus:DEVice:PTRansition is 1, then STATus:DEVice:EVENt? is
set when a power sensor is connected.
The Channel A and B sensor error bits (3 and 4) are set to:
• 1, if the P- Series, N8480 Series or E- Series power sensor EEPROM has
failed or if there are power sensors connected to both the rear and
front panel connectors.
• 0, for every other condition.
The Front Panel key press bit (bit 14), when queried with the
STATus:DEVice:EVENt? query indicates whether any front panel keys
have been pressed since power up or since you last queried the device
status register. This bit ignores the :NTRansition, and :PTRansition
registers and a :CONDition? query always returns a 0.
Querying STATus:DEVice:EVENt? clears the STATus:DEVice:EVENt? register.
