SECTION 2 TURBIDITY MEASUREMENT
2.1 Operating Controls and Indicators
2100AN Laboratory Turbidimeter controls and indicators are explained in detail
in SECTION 3 on page 31. Also, refer to Model 2100AN operating features
illustrated in Figure 6 on page 31.
Close the cell cover and press the
I/O
switch on the back instrument panel to turn
power on to the 2100AN Turbidimeter. Dark detector readings are taken
immediately after the instrument is switched on; error code E7 may be displayed
if the cell cover is left open during power up.
2.2 Measuring Turbidity
Measurements may be made with Signal Average on or off, with manual or
automatic range selection, and with Ratio on or off. Normally, measurements are
made with automatic range selection, Ratio and Signal Average on. When Signal
Average is on, the instrument's microprocessor compiles a number of readings and
averages the result. The averaged value is calculated and displayed approximately
once every second.
WARNING
The 2100AN Laboratory
Turbidimeter is not intended for
use with flammable samples or
those containing hydrocarbons or
concentrated acids that might
attack the 2100AN components.
Conduct compatibility tests prior to
analysis if the sample to be
monitored is in question. ATTENTION
Le turbidimètre de laboratoire 2100AN n’est pas prévu pour utilisation avec des liquides
inflammables ou contenant des hydrocarbures ou acides concentrés qui pourraient
attaquer les composants du 2100AN. Effectuer des essais préalables en cas de doute sur
la compatibilité de l’échantillon à contrôler.
ADVERTENCIA
El Turbidímetro de Laboratorio 2100AN no está diseñado para usarse con muestras
inflamables o que contengan hidrocarburos o ácidos concentrados que puedan atacar
los componentes del 2100AN. Ensaye antes del análisis si existe duda sobre la
compatibilidad de la muestra que se intenta analizar.
WARNHINWEIS
Das Labortrübungsmeßgerät 2100AN darf nicht zur Analyse entflammbarer Proben
oder Proben, die Kohlenwasserstoffe oder konzentrierte Säuren enthalten, welche die
Teile des 2100AN angreifen könnten, verwendet werden. Wenn die Verträglichkeit der
zu bestimmenden Probe fraglich ist, sollten vor der Analyse Tests durchgeführt werden.
AVISO
O Turbidímetro de Laboratório 2100AN não é feito com o fim de ser empregado com
amostras inflamáveis ou aquelas que contêm hidrocarbonetos ou ácidos concentrados
que possam atacar os componentes 2100AN. Os testes devem ser executados antes da
análise se existe alguma dúvida com respeito à compatibilidade da amostra a monitorar.
