My Surface Scatter 6 analyser keypad is locked and the instrument will not respond to reset. What can I do?
Summary
Surface Scatter 6 analyser and locked analyser keypad
Answer
Disconnect the wires to the 4-20 mA output, and try to reset the system again. If the analyser responds, there is likely an electro-mechanical interference in the signal wires. If the analyser does not respond, the ribbon cable connecting the keypad to the microprocessor should be replaced.
