Page 4: Safety
To replace the fuse disconnect the mains cord. Open the cover of the AC socket with a flat screwdriver. Pull out the fuse holder and replace the fuse. DANFYSIK A/S - DK 4040 JYLLINGE - DENMARK DOC.NO.UL860R/N... -
Page 5: Introduction And Specifications
0 to 600 Amp and 0 to 2000 Amp. The ULTRASTAB 860R is designed for precision current measurement and for use as current feedback element in current stabilized power supplies, where high performance is required. -
Page 6: Warranty
DANFYSIK A/S will pay or reimburse the lowest two way freight charges on any items returned to DANFYSIK A/S or our designated agent/representative provided prior written authorization for such return has been given by DANFYSIK A/S. -
Page 7: Receiving And Unpacking
The ULTRASTAB is shipped in a cardboard carton. If the equipment is damaged in any way a claim should be filed with the shipping agent, and a full report of the damage should be forwarded to Danfysik A/S or our local agent/representative immediately. -
Page 8: Mounting Requirements
Mounting requirements The ULTRASTAB 860R must be mounted horizontally and with free air passage in front and behind the unit. This ensures proper cooling of the instrument during use. Installation 1. Check that the mains voltage and frequency matches to the local requirements. - Page 9 (Pin 1 - 2 closed at NORMAL OPERATION) N.C. N.O. COMMON ZERO CURRENT N.C. (Pin 4 -5 closed at ZERO CURRENT) N.O.

Page 10: Operating Instructions
Nothing will be damaged if this sequence is not followed but the saturation effect may cause a drift in the offset. DANFYSIK A/S - DK 4040 JYLLINGE - DENMARK DOC.NO.UL860R/N... -
Page 11: How To Adopt To The Ultrastab 860R Output Signal
How to adopt to the ULTRASTAB 860R output signal In order to obtain the maximum performance of the ULTRASTAB system, it is recommended to follow the instructions listed below: 4.2.1 Connections to a low resistance load In this case it is recommended to use a cable with two twisted pairs and a common screen. -
Page 12: Test Terminals
In some cases when the instrument is used to measure AC current it can be desirable to decouple this function. The decoupling is done by moving the shortening plug P11 from position: PIN 1 + 2 to position: PIN 2 + 3. DANFYSIK A/S - DK 4040 JYLLINGE - DENMARK DOC.NO.UL860R/N... -
Page 13: The Electronics Circuit Board Assy
It is extremely important that the cable is mechanically secured with the two connector screws. Standard cable length is 2.5 metres. Larger cables - up to 30 metres length can be purchased from Danfysik, or our local representative. -
Page 14: The Compensation Output Amplifier
The relay contacts are available for an external interlock system. At the same time IC4-B switches the connection to the output amplifier from the zero detector to the bistable circuit IC7-B. DANFYSIK A/S - DK 4040 JYLLINGE - DENMARK DOC.NO.UL860R/N... -
Page 15: Current Transducer Head
Current Transducer Heads The electronics of the ULTRASTAB 860R can drive either a 600 Amp or a 2000 Amp transducer head. Please see drawing no's. 88000 and 88001. The circuit board has two connectors, and the voltage change/matching is simply done by moving the cable plug from the connectors P5 to P6, when operating in the 2000 Amp range. -
Page 16: Zero Offset Adjustment
DVM should be used, and there should be no primary current through the transducer head. For general information a more detailed description of a total offset adjustment procedure can be read I appendix D2 on pages 27 and 28.
