Status Byte Format A typical status byte (binary, 8-bit string) for the Calorimeter is shown in figure 19

with a list of the associated status bit messages. When a status bit is set to one

(1=true), the condition indicated by the message is valid. When the status bit is aero

(0=false), the condition is not valid.

CAUTION

During remote operation, periodically monitor the bus service request line. Failure to detect

the service request can result in major equipment damage.
