Device Status Register
The device status register set contains bits which give device dependent
information.
The following bits in these registers are used by the power meter:
The condition bits are set and cleared under the following conditions:

Bit Number Meaning EVENts Causing Bit Changes
1 Channel A sensor
connected
– SET: When a power sensor is connected to the Channel A input.
– CLEARED: When no power sensor is connected to the Channel A input.
2 Channel B sensor
connected
– SET: When a power sensor is connected to the Channel B input.
– CLEARED: When no power sensor is connected to the Channel B input.
3 Channel A error – SET: If the power sensor EEPROM on Channel A has failed.
– CLEARED: In every other condition.
4 Channel B error – SET: If the power sensor EEPROM on Channel B has failed.
– CLEARED: In every other condition.

This is an event, and DOES NOT set the condition register. The bit is set in the event
register which is cleared when read. Note that the transition registers are of no use
for this bit.
