Our keithley electrometer, model 6430 is suddenly showing OVP message when I tried to press ON/OFF switch. The blue light indicator is not switching ON. Also the remote amplifier is not being sensed. When I press the ON/OFF switch it is always showing OVP. Kindly help me at the earliest.

Check the OVP setting.
1. Press CONFIG, let go.
2. Press V (Source), let go.
3. Select PROTECTION with right/left arrow buttons. Press ENTER.
4. What is VOLTAGE PROTECTION set to? Is it set to NONE?

If the this OK and you still have troubles, then unit needs service.
Check with your local KI service center.
