What are the two hands on the step indicator dial, besides the indicator hand, known as?

The two hands on the step indicator dial, apart from the indicator hand, are known as drag hands. This terminology is commonly used in the context of devices such as clocks and dials where one hand represents the current value or position, while the drag hands help in setting or marking specific values for later reference.

In particular, drag hands can be adjusted and moved to track or indicate changes over time. Their ability to move independently of the indicator hand allows for enhanced functionality in monitoring or reading precise measurements. Understanding the role of drag hands is essential for effective operation of such dials, especially in applications where accuracy is critical.

The other terms that could be suggested, such as setting hands, adjustment hands, or control hands, do not align with the standard language used in the context of step indicator dials, where "drag hands" is widely recognized and understood.
