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.
