My Surface Scatter 6 instrument is not sending out the correct 4-20 mA output to my recorder/PLC/SCADA, etc.. What can be done to resolve this?
Surface Scatter 6 and no mA output
Verify that the recorder output DIP switch is set correctly. The switch for 4-20 mA should be turned on and all the other switches should be turned off. Press the REC MIN and the REC MAX keys on the analyzer. The displayed values correspond to minimum and maximum values that will be sent to your receiving instrument (chart recorder, PLC, SCADA, etc.). If the values do not match the minimum and maximum values that you want, they can be changed easily. To change the minimum value to 1.0, for example, press 1.0 (be sure to include the decimal point) and then the REC MIN key. To set the receiving device to display a maximum value of 5.0, for example, press 5.0 (include the decimal) and then REC MAX.
