reading a 16-bit unsigned integer. The value of this bit
shall always be 0.
A detailed description of each bit in the Operation Status Register follows:
• Bit 0 (Calibrating) is a condition bit which indicates the Counter is
currently performing a (front-panel invoked or HP-IB invoked)
calibration.
The condition bit is TRUE (one) during a calibration and FALSE (zero)
otherwise.
