The original AVS-47, which was introduced in 1993, has been replaced by AVS-47B which contains improvements regarding sensor grounding, immunity against input capacitance and direct interfacing with a computer. Download the renewed data sheet of this dependable and cost-effective resistance bridge and read or download material about its features.
Direct interfacing of the AVS-47B with a PC-type computer without GPIB is now possible and easy at no extra cost for LabView owners with the help of a set of Virtual Instruments.
Options for the Resistance Bridge
Read about the two options: The LabView Driver for the AVS-47B, AVS47-IB and the TS-530A, and about the Picolink Optical Fibre Link for best shielding against high-frequency interference and ground currents.Revision History
| 2012-01-11 | Added for downloading the latest AVS47-IB manual for firmware revision 3R4. |
| 2009-06-30 | Some customers have asked for very old manuals. The following two PDF manuals are now available for downloading. TS-530 manual from year 1993 includes computer control commands for the AVS-46 Resistance Bridge and the model DC900 GPIB+RS232 interface option. AVSI2 manual from year 1988 applies for the AVS-46 bridge and for our first RS232 interface option. It was designed and sold before the temperature controller was launched. |
| 2009-03-10 | LabView Driver for the AVS-47B+TS-530A+AVS47IB has been saved in LabView version 7.1. The previous version of our driver, compiled with LV 5.01, cannot be read into LabView versions starting from 8.5x. The manual has also been updated. See Downloads. |
| 2008-12-27 | Also the TS-530A is now equipped with a universal power supply accepting mains voltages from 90 to 250V. Downloadable manual has been updated accordingly. |
| 2008-10-17 | Both the AVS-47B and AVS47-IB have been equipped with new universal power supplies accepting mains voltages from 90 to 250V. Downloadable manuals have been updated accordingly. |
| 2007-08-01 | The PLM-5 Pulsed Platinum NMR Thermometer is not being produced at the moment. The manuals and related articles are still available for downloading. |

The AVS-47A is replaced by the AVS-47B revision. The main improvement is an isolated internal power supply for the output side of the primary computer interface. This eliminates some rules for providing power for the Picobus and no jumpers need to be moved when changing between direct and GPIB connections. The Picobus line remains optically isolated in both cases. The set of LabView VI:s has been modified to use the VISA architecture instead of the InPort.vi and OutPort.vi. This is due to customer feedback, that direct port access has failed to operate with some computers. Small corrections made to many pages. |

DOS programs for Picobus were removed from this site (they are still available from us upon request). As a replacement, a set of AVS-47A Virtual Instruments. for LabView is now available for free downloading. A written PDF Application Note describes these VI:s. With the aid of these VI:s, an owner of LabView 7.1 or higher can interface the basic AVS-47A (+TS-530A) with a PC type computer at no additional cost. A free standard COM port is required. |
| 2005-07-22 | Pages 6 and 35 of the AVS-47A manual contained wrong information regarding grounding of the I- sensor leads. These pages have been corrected and the previous manual has been replaced by a new one. It can be downloaded from Downloadable Files |
| 2005-04-23 | Current version of the AVS47-IB Operating manual can now be downloaded from Downloadable Files. The optional modification for 24V AC power version is described briefly, otherwise chages are minor. |
| 2004-07-27 | Operating manual for the AVS-47A version can now be downloaded from Downloadable Files |
| 2004-03-22 | The AVS-47 is replaced by improved model AVS-47A. |
| 2003-11-08 | The development phase of the PLM-5 Pulsed Platinum Thermometer has finally been completed. Download operating manuals for the PLM-5 (updated) and for its GPIB interface (new). Also the shorter description has been revised. |
| 2003-11-08 | Link to the DVS-10 Differential Resistance Bridge was removed. |
| 2002-11-18 | A 100-page operating manual for the PLM-5 can be downloaded. 1.1MB Acrobat PDF, 100 pages. Low resolution version for faster downloading. |
| 2002-09-16 | Laboratory report Noise Measurements with the PLM-5 Preamplifier has been revised. PDF 210 kB. |
| 2002-05-03 | A scanned PDF version of the manual for the very old AVS-45 is available from us upon request. |
