WH9A

This signal conditioner converts nonlinear signals generated by analyzers and noise meters, etc. to linear current or voltage signals. The instrument will approximate 31 polygonal lines maximum: Incorporation of one-chip microcomputer provides high efficiency and superior performance; Use of Handy Terminal allows easy on-site zero and span adjustment, and I/O monitoring.
