No UV attached to old Varian CIM
Posted: Thu Sep 07, 2017 1:48 pm
Hello,
My lab has an old HPLC system of different manufacturers components which gets used on and off. The computer runs a ProStar 6.3 (circa 2002?) with two DYNAMAX SD-200 pumps and a Varian Computer interface module connected with a multiple port serial cable. To the Varian CIM a Waters 486 UV detector is connected to the system.
Currently, the UV detector's lamp can be turned on/off and autozero'd with the contacts from the Varian CIM. However, the computer is picking up no UV trace. I have attached a volt meter to the analog outputs of the detector and verified that the correct voltages are being output by the 10 mV and 1 V cables. In the picture you will see the 10 mV attached to the 1 L G analog in and the 1 V attached to the 2 L G. I have already attempted both 10 mV and 1 V in the 1 L G ports alone with still no signal being detected. I am waiting to hear back from Agilant if they can find any information on the part.
Any help would be greatly appreciated.
