standard cellulose-filled molded phenolic switch form and 0,01 on
the mica-filled phenolic form used in the 510-G and 510-H units.
Max Voltage to Case: 2000 V pk,
Terminals: For 1433, low-thermal-emf jack-top binding posts on
standard.'¥4-in, spacing. Shield terminal is proyided, soldering
lugs for rear connection.
Mounting: 1433's in lab-bench cabinet, rack models include
mounting hardware; 510's complete with dial plate, knob, tem-
plate, and mounting screws,

Long-Term Accuracy: Our two-year warranty applies to the toler-
ances given below unless the resistor is damaged by excessive
current. These tolerances apply for low·current measurement at
dc or low-frequency ae (see below).
Over-all Accuracy: The resistance difference between that at any
setting and at the zero setting is equal to the indicated value
:=:(0,02%
+
2 mO).
Incremental Accuracy: See table. This is the accuracy of the
change in resistance between any two settings on the same dial.
Max Current: The
max
current for each decade is given in the
table below and also appears on the panel of each decade box
and on the dial plate of each decade resistance unit.
Frequency Characteristic: Refer to Section 3.
Zero Resistance (R

0.001
Q
per dial at
dCI
0.04
Q
per dial at
1 MHz; proportional to square root of frequency at all frequen-
cies above 100 kHz.
Temperature Coefficient of Resistance: Less than ±10 ppm per
degree C for values above 100
Q
and ±20 ppm per degree C for
100
Q
and below, at room temperatures. For the 1433's the box
wiring will increase the over-all temperature coefficient of the
0.1- and O.01-g decades.
Switches: Quadruple-leaf brushes bear on lubricated contact studs
of :Va·in. diameter in such
a
manner as to·avoid cutting but· yet
give a good wiping action. A cam-type detent is provided. There
areeleYen contact points
(O
to 10 inclusiye). The switch resist-
ance is less than 0.0005
g,
TheeffectiYe capacitance is of the
order of 5 pF, with a dissipation factor of 0.06· at 1 kHz for the
