Hi friends:

My patch clamp amplifier, a HEKA EPC 7 plus, has completely gone
mad.The clipping LED is constantly on, and in the LCD displays a message "LO
BAT" and numbers that doesn´t make sense.

Has anybody experienced this problem. Any battery inside this amplifier?
Obviously this happens now that I have to get some results for the next
week.

I have unplugged everything except the power cable.

Thandks in advance, Claudio.

I've never seen an error like that.

Do you still get it when you have a model cell plugged into the
headstage or just a resistor between the headstage earth and the
signal pin? What about if you unplug the headstage from the back of
the amp? I've seen something similar that was caused by a broken
headstage. When you unplugged the headstage, the amp started behaving
again.

I'm also wondering, are you sure it is saying "LO BAT". Just because
A's and T's are are hard to write on your standard LCD.
