1. INTRODUCTION
1.1. SCOPE
This document describes the operation additional temperature functionality provided by the T-
Option in the 6622A Series of Automatic DCC Resistance Bridge.
1.2. GENERAL DESCRIPTION
The model 6622A Series T-Option is and software and embedded software upgrade to your 6622A
Series bridge. This upgrade includes functions and features that optimize primary temperature
measurement, and calibration using your 6622A. These functions primarily include measurement
operation at higher speed and temperature conversion. The installation of the T-Option does not
change to resistance operation of the 6622A.

1 - Specifications are based on 20 second reversal rate, 100 µW Rspower dissipation and temperature of 23 °C ± 3 °C.
2 - Lowest possible RxRatio is defined as Rxlow = Rsx .08 and Maximum possible RxRatio is determined by Rxhigh = Rs x 107.5.
3 - Maximum Upper Range is limited to 134 kΩ for the T-Option on all models with the maximum Rsallowed as 10 kΩ.
4 - Ranges below 1 Ohm are only available for a Rsof 1Ω.

Notes:
1. The Relative Uncertainty specification is that measurement uncertainty of the 6622A
Series Automatic DCC Resistance Bridges and 2 times the standard deviation of the
sample set, but does not include the uncertainty of the Reference Standards. This
Relative Uncertainty specification is applicable after the measurement has stabilized
for the applicable Itest current applied to Rx, and for the reversal rate that is greater
than or equal to those in the recommended test setups in Section 3. To calculate the
Total Uncertainty of the Resistance Measurement, add the uncertainty of the
Reference Standard to the Relative Uncertainty.
2. The Relative Uncertainty specification is based on the Resistance Under Test being
connected across the Rx terminals and the Reference Standard being connected
across the Rs terminals.

3. OPERATING INSTRUCTIONS
3.1. FRONT PANEL OPERATING PROCEDURE
The 6622A Series T-Option provides temperature related option to the manual operation from the
front panel. The BridgeWorks-C Software User's Manual contains the operating instructions for
fully automatic software control of the model 6622A Series T-Option via its computer system.
3.2. 6622A SERIES T-OPTION RESISTANCE/THERMOMETRY MEASUREMENT
BRIDGE
The front panel operation of the model 6622A with the T-Option does not change for resistance
measurement. All relevant in depth information on this mode of operation can be found in the
OM6622A Operator’s manual. The following information describes typical displays and
corresponding menu descriptions for associated function keys for the additional functionality
provided with the T-Option. Figures 3-1, 3-2, and 3-3 illustrate the model 6622A Series menu tree
with the T-Option installed.
