STABILITY
OF OUTPUT
The
following
stability specifications
apply at the
standard
reference conditions noted
under ACCURACY
OF OUT-
PUT:
Model 341 A:
1 0V range
(whichever
is greater)
±0.0007% of setting or 5 uv per hour
±0.003% of setting or 15
uv
per month
1 00V range (whichever
is greater)
±0.0007% of setting
or 1 0 uv per hour
±0.003% of
setting or 25 uv per month
1 000V range (whichever is greater)

OUTPUT
CURRENT
0
to 25 milliamps at any output voltage.
OVERCURRENT PROTECTION
Automatically limits output current at any present level
between
1 and 25 milliamps via continuously variable front
panel control. Panel lamp
illuminates during limiting.
SHORT-CIRCUIT PROTECTION
At output voltage dial settings of 299
.99X (299.999X on
the Model
343 A) or less, normal operation is restored upon
removal
of
overload.
At output
voltage
dial
settings
of
300.000 (300.0000 on the Model
343A)
or above, the
instrument
trips
to STANDBY when the output
is
short-
circuited.
RIPPLE
AND NOISE (all
frequencies)
Model 341A:
60 Hz Line
-
Less than 100 uv rms
or 1 mv
p-p.
400 Hz Line
-
Less than
100
uv
rms or 2 mv
p-p.
Model 343A:
60
Hz
Line
-
Less than 50 uv rms or 400 uv
p-p.
400 Hz
Line
-
Less than 100
uv
rms or
2
mv
p-p.
SETTLING TIME
Model
341 A: Within
50
ppm of final output
in 5 seconds.
Model
343A:
Within
25
ppm of final output
in 5 seconds.
LINE REGULATION
0.0005% of setting +
25 uv for
a 10% line voltage change
from nominal.
LOAD REGULATION
0.0005% of setting +
25 uv for a full load
change.
ISOLATION
Either output terminal
may be floated up
to 500 volts dc
from chassis
ground.
REMOTE SENSE
Separate
terminals are provided
for sensing the
output
vol-
tage directly at the
load, thereby eliminating
errors due to
voltage
drop in the instrument-to-load
connecting wires.
WARM-UP
TIME
Model 341A: Within
50
ppm of
final
output
at
turn-on.
Within
1
5
ppm
of final output in 30
minutes.
Model
343A: Within
25
ppm of
final output at turn-on.
Within
5
ppm of final output
in 30 minutes.
INPUT POWER
