Mich. Admin. Code R. 408.15736 - Weight indicators
Rule 5736.

A weight indicator shall be installed and used on all operating drilling and
well servicing rigs. It shall be so constructed, installed, and maintained so
as to register an indication of plus 5% at maximum hook loading of the
suspended load.
(2) The weight
indicator shall be checked monthly for calibration by comparing its reading
with the calculated drill string or tubing string weight, with adjustment made
as necessary.
(3) The weight
indicator shall be mounted so the gauge is easily visible to the operator
standing at the brake position.
(4)
Where an employee would be exposed to a hazard from a weight indicator, or a
component of a weight indicator, installed on the deadline, the indicator or
component shall be secured with a separate safety line or chain.
