CALIBRATION of the x0.1 RANGE
LOW VOLTAGE / LOW NOISE HEADSTAGE
(SEC SYSTEMS with Adapted Amplifier)
This headstage has an output current range of

15nA into maximum 100 M

, and the noise and bias current
are reduced by a factor of 10 compared to the standard headstage. Therefore, it is recommended for whole
cell patch clamp recordings.
Current related signals:

CURRENT DISPLAY: X.XXX pA (100 = 100 pA)

HOLDING CURRENT: X.XX nA (100 = 1 nA)

Input sensitivity: BNC labeled 1 nA/V i.e. 1V = 1nA
BNC labeled 0.1 nA/V . 1V = 100 pA )

Output sensitivity: 1V/nA-100V/nA, with 1 V/nA (= 1 mV/pA) 100 pA is 100 mV.

BRIDGE BALANCE: standard as indicated at the front panel (100 = 100 M

)

R
EL
mode display: standard as indicated at the front panel (100 = 100 M

)
The potential input and output signals are not affected.
