Rear Panel - Warner OC-725C User Manual

Control Description

Rear Panel

The line power connector and fuse are located on the rear panel. Operating voltage is
specified on the MODEL/SERIAL NUMBER sticker applied to the rear of the instrument.
The rear panel also contains Ve x10 and GAIN TELEGRAPH output BNCs, the ALARM
switch and instrument GROUNDS.
NOTE: Verify that the instrument is wired for the proper voltage
before connecting the line cord.
The Ve x10 output BNC monitors the voltage of the current electrode (x10) when
the CLAMP MODE SELECTOR switch is off
The GAIN TELEGRAPH output BNC provides a DC voltage indicating the gain setting of
the instrument. The output varies from 0.2 to 2.6 volts in 200 mV steps as shown in the
appendix.
ALARM switch - Activates or deactivates the OVER VOLTAGE current electrode audible
alarm.
GROUNDS - Both CIRCUIT and CHASSIS grounding posts are located on the rear panel.
CHASSIS is common with the instrument enclosure and connected to earth through the
power line cord. A shorting link allows for interconnection of the two grounds. In most
experimental setups, separating the grounds will result in minimizing 50/60 Hz signal
interference from ground loops. However, trial and error will determine the best results.
NOTE: For safe operation, the ground pin on the power plug must
not be removed and the use of "cheater" plugs must be avoided.
Additional Components
Voltage Recording Headstages
7250V PROBE (Standard Version)
The voltage probe is an active headstage
housed in a 1.25 x 5 cm cylinder (dia. x length).
The probe body is nickel plated and epoxy sealed for corrosion resistance.
NOTE: The outer shell is electrically driven at the input potential.
The microelectrode holder mates directly to the 2 mm input pin on the probe body. A
mounting block and handle are also supplied and facilitate attachment of the probe to
a micromanipulator. The handle can be mounted either axially or perpendicular to the
probe body.
