Applies to X-Y recorders used for recording analogue electrical signals. Describes requirements for X-Y recorders, which can be used for measuring a voltage or a current, another electrical quantity or a non-electrical quantity. Does not apply to X-T recorders. For X-Y recorders incorporating a time base, applies to the X-Y function only. Does not apply to special purpose recorders which are covered by their own IEC standards. Does not cover safety requirements.
