6.4. Conductivity-Resistivity QC-Kit Test Plug
The QC-Kit test plug fulfills the requirements of the United States
Pharmacopeia (USP).
6.4.1
Introduction
The test plug consists of 2 high precision resistors for conductivity
and temperature.
The plug has a resistor of
5000
(+/- 1%) for temperature
181800
(+/- 1%) for conductivity.
NOTICE:
Keep test kit absolutely dry!
Several variables enter into the calculation of specific conductivity.
Values like the cell constant, temperature compensation algorithm,
cable length and temperature correction of the sensor are stored in
the memory of the conductivity instrument.
Test mode
For a quick and easy test, the AMU Rescon transmitter has the test
mode <Transmitter check> that enables testing without changing
any of these values. When leaving the test mode, all parameters
will be set back to their original value.
