9336 & 9337 Series
Precision High Value Air Resistance Standards
High to Ultra-High Value Laboratory Air Resistance Standards
GUILDLINE INSTRUMENTS 9336 & 9337 SERIES of
Resistance Standards are designed as very high stability
calibration laboratory standards for accurate resistance
calibration in air, between 10 M and 10 P. These new
resistors complement the 9334 and 9336 Resistance
Standards available from 1 to 100 G with many custom
and intermediate values for special applications.
These resistors are also suitable for use as calibration
standards for the Guildline 6500 Series of Teraohmmeters to
include the new 6520 Programmable Teraohmmeter. They
are also an excellent choice for the calibration of other high
to ultra high ohms measuring instruments and standards.
With a wide laboratory environment from18 0C to 28 0C, they
can be used as working standards or reliable, ruggedized,
transportable transfer standards. They are extremely useful
for the calibration of resistance ranges of multi-function
9336 & 9337 SERIES FEATURES calibrators and high accuracy digital multimeters, as well as
being used in more classical standards and calibration
12 Month Stabilities Low as 10 ppm laboratory applications where the need for high accuracy
high ohms values are required.
Wide Operating Range 18 0C to 28 0C
Resistance Range 10M to 100 G
The 9336 and 9337 Series of Precision Resistance
Standards can be used as laboratory standard or for
Hermetically Sealed portable applications requiring high accuracy with
ISO 17025 Calibrations Available resistance values from 10 M to 10 P.
Compact and Ruggedized The resistor elements are securely mounted to the inside of
Nominal Initial Accuracy < 2 ppm a rugged hermetically sealed, shielded, aluminium

The 9337 Standard Resistors are 3 terminal devices. The 3
terminal design minimizes the effect of current leakages
from the source and output connectors. The high stability is
achieved by use of a resistance divider network of the form
