LOCAL.
The LOCAL key is used to return the
instrument from remote control by
the IEEE-488
B U S
or the RS-232C op-
tional interface to front-panel con-
trol.

REMOTE
The REMOTE key is used to place the
controller under remote control and
to disable the front panel.
When

REMOTE SENSOR
ID
The REMOTE SENSOR ID connector is
connected to
the REMOTE POSITION
DATA output of a Model
8084
or Model
8085
Sensor Scanner or a Model
SW-10A ten-position switch.
This
input is called the REMOTE POSITION
DATA
and
allows
the
user
to
automatically call up different cu-
rves for different sensor/channel
positions when the instrument is
used with either remote switch (see
Section
3.9.2).
The Parallel input
data format is given in Table 3-5.
The user may supply to the REMOTE
SENSOR ID his own parallel BCD
5
volt signal referred to the DIGITAL
GROUND on pin
12.

HEATER
CURRENT
L I M I T
The DRC-93C Temperature Controller
has a current drive output with a
maximum current rating of one ampere
unless the optional
1 . 5
ampere out-
put (W60) was ordered, or the cur-
rent-limiting vernier has been set
at a lower value.
with the current-limiting vernier on
the back of the instrument, the out-
put current on the
MAX
scale can be
limited anywhere between
1
ampere
and the maximum current for the
10
-1 scale
(330 mA).
This allows
the user to limit the maximum power
to between 50 watts and
5
watts,
dependent on his requirements.
