4.13.5.3. Turning the Analog Output Over-Range Feature ON/OFF
In its default configuration a ± 5% over-range is available on each of the 9110TH/M’s
analog output channels. This over-range can be disabled if your recording device is
sensitive to excess voltage or current.
Note Instruments with current range options installed on one or more of the
outputs often are delivered from the factory with the over-range feature
turned OFF on those channels.
