Single Hall effect sensor Probe features: Autorange works in DC and AC measurement modes. See the table on page 25 for our stock probes recommended for use with this gaussmeter. If no sensitivity information is available, the Model reverts to resistance measurement. It’s a community-based project which helps to repair anything. Indicated by value in above table for periodic mode and shorted input Display resolution: The display can also be configured to show probe temperature or frequency.

In wide band AC mode, the signal can be viewed on an oscilloscope to observe the shape of AC fields. The buffer can be filled at high speed, up to readings per second, which is as much as ten times faster than the computer interface.
The Model alleviates most of the hassle by allowing users to match probes to extensions in the field.
User-specified defaults same as Voltage Output 2 Resolution: The uncalibrated version requires the operator gaudsmeter load the matching probe data file into the cable PROM directly from the Model front panel.
The peak reading can be held for an unlimited length of time with no sag.
Lake Shore recommends an annual recalibration schedule for all precision gaussmeters. If no sensitivity information is available, the Model reverts to resistance measurement. General measurement Does not include probe error, unless otherwise specified Input type: Voltage output labviwe field value, generated by DAC Range: User specified defaults same as Voltage Output 2 Resolution: Max Peak Hold On — the display configured to both show the positive and negative Peak readings.
When operating in RMS mode, the gaussmeter can display the frequency of the modek AC field along with a field reading up to 20 kHz.
The sampling frequency of the Model allows gausdmeter accurate RMS measurement to be made on signals of up to 20 kHz. Model probes are calibrated in this way to provide the most accurate DC readings.
The display can also be configured to show probe temperature or frequency. Voltage output of field value, generated by DAC Range: One dxp the built-in analog voltage outputs drives the program input of the power supply for either bipolar or unipolar operation. Keeping probes and their extensions from getting mixed up can become a problem when more than one probe is in use.
Model probes are calibrated in this way to provide the most accurate DC readings. In Peak mode, the gzussmeter can be used to view a pulse shape or other characteristic of a momentary signal. Those signals are then sent to the digital signal processing DSP circuitry where the signal processing is done and the readings are filtered. Stored information can be viewed on the front panel and read over the computer interface to ensure proper mating.
Pulsed fields are measured in Peak mode, which is a natural extension of the high-speed data acquisition necessary for DSP operation.
Indicated by value in above table for periodic mode and shorted input Display resolution: The Hall voltage produced by the sensor is fed back into the instrument and sent through a programmable gain stage.
Lake Shore Cryotronics, Inc. Front panel programmable sensitivity and serial number for user-supplied Hall sensor Extension cable compatibility: It turns out that a signal can only be properly labvidw if the signal does not contain frequencies above one-half of the sampling rate.
Linearity compensation, temperature compensation, auto probe zero, and hot swap Measurement features: Following are three examples of the various display configurations: DSP technology creates a solid foundation for accurate, stable, and repeatable field measurement while simultaneously enabling the gaussmeter to offer an unequaled set of useful measurement features.
The operator can also control display brightness. The Model can also be used to sample field changes at readings per second that can later be read over the interface to illustrate the shape of pulses or other waveforms. Following are four examples of the various display configurations:
