Bath Headstage - Warner OC-725C User Manual

Control Description
7255DI Differential Probe (Optional)
This voltage probe is designed for applications where two oocytes share a common
bath or where the voltage drop across the solution resistance is to be measured and
subtracted from Vm. The headstage housing is approximately 2 cm longer than that of
the 7250V PROBE and has two additional inputs; CIRCUIT GROUND and V DIFFERENTIAL.
When the two inputs are shorted, the probe functions exactly the same as the standard
single ended 7250 PROBE.

Bath Headstage

The BATH PROBE is housed in a 2.8 x 3.5 x 4.2 cm
aluminum enclosure. Inputs are two 1 mm pin jacks
labeled I SENSE and I OUT. The case is electrically
grounded and a pin jack is located on the side for
connecting to shields.
A plastic plate with two screw mounting slots
is attached to the probe base. The BATH PROBE
connects to the control unit with a 6 pin connector
Current Electrode Cable
A two meter shielded cable is supplied with a 2 mm pin jack on one end to mate
with the electrode holder and a 3-pin connector on the other end to mate with the
instrument. The electrode holder has a handle for
mounting in a micromanipulator.
Model Cell
The model cell supplied with the OC-725C is useful
as a training aid and as a calibration and test device.
It has connections for the voltage and current probes and to the bath clamp allowing all
aspects of the amplifier's function to be tested.
Comments
Connecting to Line Power
The model OC-725C is supplied with a 3-conductor power cord. One conductor provides
a connection between the instrument housing and the earth ground. Safe operation of
the instrument will be assured provided that the ground circuit in the power outlet is
wired correctly and is connected to earth.
